CAD Perfect® Conversion with CAD / CAM Services

CATIA pricing isn’t publicly fixed and varies a lot by modules, licensing type, region, and whether it’s enterprise-negotiated (which it usually is). But I can give you realistic industry ranges so you understand what “CATIA with options” actually costs.

Baseline: CATIA is Enterprise Software

CATIA is typically sold through Dassault Systèmes resellers with modular licensing.

You don’t buy “one CATIA”—you assemble a configuration like:

• Mechanical design
• Surface design
• Assembly design
• MBD (Model-Based Definition)
• Simulation
• Manufacturing
• PLM integration

Each “option” is a paid module.

Typical Cost Ranges (Real-World Estimates)

1. Entry-Level CATIA Configuration (rare in aerospace)

• Basic mechanical + assembly + drafting

👉 ~$5,000 to $10,000 per seat per year

2. Professional Mechanical + Surfacing Setup

• Advanced part design
• Surface modeling
• Large assembly tools

👉 ~$10,000 to $25,000 per seat per year

3. Aerospace / Full Engineering Stack (“with options”)

Includes things like:

• Advanced surfacing (Class A)
• MBD / GD&T integration
• Kinematics
• Advanced assembly management
• Manufacturing prep
• Simulation modules (optional add-ons)

👉 ~$20,000 to $40,000+ per seat per year

4. Full Enterprise / PLM-Connected Stack

When CATIA is bundled with:

• 3DEXPERIENCE
• Simulation tools
• Manufacturing planning
• Collaboration + cloud platform

👉 $40,000 to $70,000+ per seat per year (sometimes more)

License Type Matters A LOT

Named User (most common now)

• Per engineer license
• Annual subscription
• Highest flexibility

Floating / Network

• Shared pool of licenses
• More expensive upfront but efficient for large teams

Enterprise Agreements

• Custom pricing
• Includes support, PLM, training, cloud services

What Drives CATIA Cost Up

You pay more for:

• Advanced surfacing (Aerospace Class A)
• MBD / PMI capabilities
• Large assembly performance tools
• Aerospace industry templates
• PLM integration (3DEXPERIENCE)
• Simulation modules
• Manufacturing (CNC, composites, tooling)

Why It Feels Expensive vs SOLIDWORKS

CATIA is not just CAD—it’s:

• Engineering platform
• Digital thread backbone
• Aerospace-grade design system
• PLM-integrated environment

So you're paying for:

• Compliance capability
• Configuration control
• Multi-discipline engineering
• Lifecycle traceability

Practical Reality (Important Insight)

Most companies don’t buy “full CATIA with everything.”

Instead they:

• Start with a core CAD package
• Add only needed modules
• Expand as programs require

Aerospace OEMs like:

• Airbus
• Boeing

often have multi-million-dollar annual CATIA + PLM environments spread across thousands of users.

Bottom Line

• Entry use: ~$5K–$10K/year per seat
• Serious engineering: $10K–$40K/year per seat
• Full aerospace digital engineering stack: $40K–$70K+/year per seat

If you’re thinking strategically:

CATIA becomes expensive when you buy capability for the entire digital engineering lifecycle, not just modeling parts.

If you want, I can break down:

• CATIA vs NX total cost of ownership
• Or what modules you actually need for CAD services / reverse engineering / MBD work (so you don’t overbuy)

If your long-term goal is to build a high-end aerospace/defense CAD services practice focused on CAD remastering, MBD, PLM integration, digital twins, and sustainment programs, Creo is generally closer to the enterprise engineering workflows used in those environments, while SOLIDWORKS remains extremely valuable for serving a wider manufacturing customer base.

‍

And think of it this way, if my goal is to create a part or a good 3D assembly - SolidWorks. If however you wish a true interactive Parametric Design - PTC Creo. Creo is up there with NX and Catia for handeling complex assemblies. However, SolidWorks is used - and sold 5-1 vs. PTC Creo worldwide.

The choice between SOLIDWORKS and AutoCAD is less about which is better and more about what you're trying to accomplish. They were originally designed for different purposes.

The Fundamental Difference

SOLIDWORKS

SOLIDWORKS is a 3D parametric mechanical design system.

It is intended for:

• Parts
• Assemblies
• Mechanical products
• Manufacturing
• Engineering analysis

AutoCAD

AutoCAD is primarily a drafting and documentation platform.

It is intended for:

• 2D drawings
• Schematics
• Layouts
• Floor plans
• General drafting

Example: Designing a Gearbox

In AutoCAD

You would typically:

• Draw views manually
• Create dimensions manually
• Manage changes manually
• Update drawings manually

In SOLIDWORKS

You would:

• Build a 3D assembly
• Create relationships between components
• Generate drawings automatically
• Update all views automatically when designs change

For mechanical products, this can save enormous amounts of time.

Parametric Design

One of the biggest advantages of SOLIDWORKS is parametric modeling.

For example:

If a shaft diameter changes:

25 mm → 30 mm

Associated features can update automatically.

In AutoCAD, many changes must be made manually.

Assemblies

SOLIDWORKS

Designed for:

• Machines
• Robots
• Industrial equipment
• Consumer products

Capabilities include:

• Motion studies
• Interference detection
• Assembly relationships
• Exploded views

AutoCAD

Can represent assemblies but lacks the same mechanical design capabilities.

Manufacturing Integration

SOLIDWORKS is built around manufacturing workflows.

Supports:

• CNC manufacturing
• CAM integration
• BOM generation
• Sheet metal design
• Weldments
• Mold design

AutoCAD is primarily a drafting tool and generally requires additional systems for these workflows.

Simulation

SOLIDWORKS supports:

• Stress analysis
• Motion analysis
• Thermal studies
• Design optimization

AutoCAD is not intended for engineering simulation.

Reverse Engineering

If you're creating CAD models from:

• Legacy drawings
• Laser scans
• Physical parts

SOLIDWORKS is generally much more effective because it produces parametric 3D models that can be modified and reused.

AutoCAD is often used to document the results but not as the primary modeling environment.

Product Lifecycle Management

SOLIDWORKS integrates with:

• SOLIDWORKS PDM
• Manufacturing systems
• ERP systems

This supports:

• Revision control
• Engineering change management
• Configuration control

AutoCAD can participate in these workflows but is not usually the centerpiece of them.

When AutoCAD Is the Better Choice

AutoCAD remains excellent for:

• Architectural drafting
• Facility layouts
• Electrical schematics
• Piping diagrams
• Site plans
• Legacy drawing conversion
• General technical documentation

Many industries still rely heavily on AutoCAD drawings.

When SOLIDWORKS Is the Better Choice

Choose SOLIDWORKS if you need to:

• Design manufactured products
• Build assemblies
• Create production-ready models
• Perform engineering analysis
• Generate BOMs
• Support manufacturing workflows

Examples:

• Machinery
• Automation systems
• Medical devices
• Consumer products
• Industrial equipment

Aerospace & Defense Perspective

For aerospace and defense work:

• AutoCAD is often used for documentation, facilities, and legacy drawings.
• SOLIDWORKS is commonly used by suppliers and equipment manufacturers.
• Large OEM programs frequently use:
  • CATIA
  • Siemens NX
  • PTC Creo

If your goal is to build expertise in CAD services, reverse engineering, CAD remastering, digital twins, and manufacturing support, SOLIDWORKS generally offers far more engineering capability than AutoCAD because it creates intelligent 3D models rather than primarily serving as a drafting environment.

‍

SOLIDWORKS and Autodesk Inventor are both powerful mid-market mechanical CAD systems. Neither is universally "better"—the best choice depends on your customers, workflow, and long-term goals.

Inventor

Often paired with:

• Autodesk Vault

Both provide:

• Revision control
• File management
• Change tracking

Aerospace & Defense Considerations

For serious aerospace OEM work, neither SOLIDWORKS nor Inventor is typically the primary design platform.

Most major aerospace and defense organizations rely heavily on:

• CATIA
• Siemens NX
• PTC Creo

However, SOLIDWORKS and Inventor are frequently used by:

• Suppliers
• Tooling companies
• Fixture designers
• Equipment manufacturers
• Small engineering firms

For a CAD Services Business

If you're offering:

• General mechanical design services
• Product development
• Equipment design
• Manufacturing support

SOLIDWORKS often provides the broadest market reach because of its large user base.

If you're targeting:

• Autodesk-centric customers
• AutoCAD-heavy organizations
• Factory and plant equipment projects

Inventor can be an excellent fit.

Practical Recommendation

If your goal is to build a CAD services business that serves a wide range of manufacturing clients:

1. Learn SOLIDWORKS first.
2. Add Inventor if you encounter Autodesk-centric customers.
3. Develop expertise in MBD, PLM, CAD translation, reverse engineering, and CAD remastering.
4. If you plan to pursue aerospace and defense programs, invest heavily in CATIA and Siemens NX, since those platforms are more commonly associated with high-end digital engineering, digital twin, and lifecycle management environments.

‍

Choosing between CATIA and Siemens NX depends heavily on your industry, customers, and workflow. Both are considered top-tier CAD platforms for aerospace, defense, automotive, and complex industrial products.

than many traditional CAD environments.

Reverse Engineering and CAD Remastering

For legacy equipment projects:

Both platforms perform well, but NX often has advantages in:

• Scan-to-CAD workflows
• Manufacturing integration
• Digital twin programs
• PLM connectivity

CATIA remains very strong when the deliverable must match aerospace customer requirements.

Aerospace & Defense Perspective

CATIA Advantages

‍

If you think we are at how Ironman ran his CAD system, no. However...

‍

Yes—AI-driven CAD design is already a reality, but not in the sense of a fully autonomous AI that can replace experienced aerospace, defense, or mechanical engineers.

Today, AI is most effective as a design assistant, helping engineers create, optimize, analyze, and document designs faster.

Where AI Is Working Today

Generative Design

Engineers specify:

• Loads
• Constraints
• Materials
• Manufacturing methods

The AI generates multiple design alternatives that meet those requirements.

Examples include:

• Autodesk Fusion
• Siemens NX
• PTC Creo

Typical applications:

• Lightweight brackets
• Aerospace structures
• Heat exchangers
• Additive manufacturing parts

CAD Automation

AI can:

• Create standard features
• Generate parametric models
• Automate repetitive drafting
• Suggest dimensions and constraints

Tasks that once took hours can often be completed in minutes.

Reverse Engineering

For legacy equipment remastering, AI can help:

• Interpret scanned geometry
• Recognize holes, fillets, and pockets
• Convert mesh data into CAD features
• Classify parts

This is particularly valuable for aerospace and defense modernization programs.

Design Optimization

AI can evaluate thousands of design variations and optimize for:

• Weight
• Strength
• Cost
• Manufacturability
• Thermal performance

Engineers still define the objectives and validate the results.

MBD and Documentation

AI can assist with:

• GD&T recommendations
• Drawing creation
• BOM generation
• Technical documentation
• Compliance checks

What AI Cannot Reliably Do Yet

AI still struggles with:

Complex System Design

Examples:

• Aircraft subsystems
• Missile systems
• Naval systems
• Industrial machinery

These require engineering judgment, trade studies, certification knowledge, and domain expertise.

Certification-Critical Designs

Organizations such as Federal Aviation Administration and the United States Department of Defense require rigorous verification and validation.

Engineers remain responsible for approving designs.

Understanding Real-World Context

AI may optimize a bracket for weight but miss considerations such as:

• Maintenance access
• Tool clearance
• Supplier capabilities
• Field repair requirements
• Program-specific standards

Human expertise remains essential.

Aerospace & Defense Outlook

The industry is increasingly adopting AI for:

• Generative design
• Automated CAD remastering
• Digital twin development
• Predictive maintenance
• Engineering knowledge retrieval
• PLM data analysis

Major companies such as Boeing, Lockheed Martin, Northrop Grumman, and RTX are investing heavily in AI-enabled digital engineering workflows.

The Biggest Opportunity Right Now

For a CAD services business, the strongest near-term opportunity is not "AI designs everything."

It's using AI to accelerate:

1. Legacy drawing conversion
2. CAD remastering
3. Scan-to-CAD workflows
4. Feature recognition
5. MBD creation
6. PLM data migration
7. Digital twin generation

These areas can often achieve productivity improvements of 2×–10× while still keeping engineers in control of the final deliverables.

The most successful engineering organizations today are typically combining human engineering expertise + CAD platforms + PLM + AI assistance, rather than attempting to fully automate the design process.

‍

PLM (Product Lifecycle Management) CAD data is important because it transforms CAD files from isolated design documents into controlled engineering assets that can be managed, shared, traced, and maintained throughout a product's entire lifecycle.

Without PLM, you may have excellent CAD models but poor control over revisions, approvals, manufacturing releases, and long-term sustainment.

What PLM Does for CAD Data

A CAD file by itself tells you:

• Geometry
• Dimensions
• Assemblies
• Design intent

A PLM system adds:

• Revision history
• Change management
• Approval workflows
• Bills of Materials (BOMs)
• Configuration management
• Supplier collaboration
• Manufacturing release status
• Traceability

Common PLM platforms include:

• Siemens Teamcenter
• PTC Windchill
• 3DEXPERIENCE
• Aras Innovator

Why It Matters in Aerospace & Defense

Configuration Control

A defense program may have thousands of parts and hundreds of engineering changes.

PLM answers questions such as:

• Which revision is approved?
• Which aircraft received the modification?
• What parts are interchangeable?
• Who approved the change?

Without PLM, those answers often require manual investigation.

Engineering Change Management

Changes happen constantly.

Examples:

• Material substitutions
• Weight reductions
• Supplier changes
• Obsolescence replacements

PLM tracks:

Original Design
     ↓
Change Request
     ↓
Engineering Review
     ↓
Approval
     ↓
Release
     ↓
Manufacturing Update

Every step is documented and auditable.

Digital Thread

PLM is often the backbone of a digital thread.

It connects:

Requirements
    ↓
CAD Models
    ↓
MBD
    ↓
Analysis
    ↓
Manufacturing
    ↓
Inspection
    ↓
Maintenance

This allows data to flow across departments instead of existing in disconnected systems.

Legacy Equipment Sustainment

For older military and industrial equipment, PLM becomes even more valuable.

When reverse engineering or remastering legacy equipment, PLM helps preserve:

• Native CAD models
• Engineering drawings
• Inspection data
• Technical publications
• Maintenance records

This creates a long-term digital engineering repository.

Risks of Managing CAD Without PLM

Organizations often encounter:

• Duplicate models
• Lost files
• Incorrect revisions
• Uncontrolled design changes
• Manufacturing mistakes
• Audit failures
• Knowledge loss when employees leave

A common problem is multiple engineers working from different revisions of the same model.

PLM prevents this through controlled check-in/check-out and release processes.

Business Benefits

Faster Engineering

Engineers spend less time searching for files and more time designing.

Reduced Manufacturing Errors

Production uses approved, released data.

Better Compliance

Supports standards and regulatory requirements.

Lower Sustainment Costs

Critical for aerospace, defense, energy, and transportation assets that remain in service for decades.

Why It Matters for CAD Service Providers

If you're offering:

• CAD conversion
• CATIA services
• Siemens NX services
• Creo services
• Legacy equipment remastering
• MBD creation

then PLM knowledge can significantly differentiate your business.

Many aerospace and defense customers are not simply buying CAD models—they need:

• Controlled engineering data
• Configuration-managed datasets
• MBD-ready deliverables
• Digital thread integration
• Digital twin foundations

In those environments, the CAD model is only part of the deliverable. The real value comes from delivering CAD data that is structured, traceable, reusable, and fully integrated into the customer's PLM ecosystem.

‍

PLM is not easy or quick to setup, but in many cases is very important to most companies who manufacture and build something.

An effective aerospace and defense CAD workflow is typically built around digital engineering, configuration control, Model-Based Definition (MBD), and strict compliance requirements. The goal is to create a complete digital thread from requirements through manufacturing, maintenance, and sustainment.

1. Requirements and Program Planning

Before CAD modeling begins:

• Capture system requirements
• Define design standards and CAD conventions
• Establish configuration management procedures
• Define security and export-control requirements (ITAR, EAR, CMMC, etc.)
• Create part numbering and revision schemes

Common tools:

• IBM DOORS
• Jama Connect
• Siemens Teamcenter

2. Master CAD Modeling

Engineers create authoritative 3D models using:

• Parametric design
• Top-down assembly design
• Skeleton models
• Design templates
• Standardized libraries

Typical CAD platforms:

• CATIA
• Siemens NX
• PTC Creo

Best Practice

The 3D model becomes the authoritative source of truth rather than the drawing.

3. Model-Based Definition (MBD)

Instead of relying solely on 2D drawings:

• GD&T embedded in 3D model
• Surface finish requirements
• Material specifications
• Manufacturing notes
• Inspection requirements

Benefits:

• Reduced drawing creation effort
• Fewer interpretation errors
• Better automation

Example standards:

• ASME Y14.41
• SAE International digital product definition standards

4. Product Data Management (PDM) / PLM

All CAD files should be controlled within a PLM environment.

Workflow:

1. Engineer checks out model
2. Makes changes
3. Submits for review
4. Approval workflow
5. Release to production

Common systems:

• Teamcenter
• Windchill
• 3DEXPERIENCE

Critical capabilities:

• Revision control
• Change tracking
• Effectivity management
• Audit trail

5. Simulation and Verification

CAD models flow directly into analysis.

Structural

• FEA
• Fatigue analysis
• Vibration analysis

Thermal

• Heat transfer
• Environmental testing

CFD

Tools include:

• ANSYS
• Abaqus
• STAR-CCM+

6. Manufacturing Digital Thread

CAD feeds manufacturing directly.

Outputs:

• CNC toolpaths
• Inspection programs
• Additive manufacturing files
• Assembly instructions

Typical workflow:

CAD → MBD → CAM → Inspection → Production

This reduces rework and manual data entry.

7. Configuration Management

Especially important for defense programs.

Every change should be:

• Documented
• Approved
• Traceable
• Reproducible

Processes:

• Engineering Change Requests (ECR)
• Engineering Change Orders (ECO)
• Configuration audits
• Baseline management

8. Legacy Equipment CAD Remastering

For older DoD platforms:

Scan

• Laser scanning
• Structured-light scanning
• CMM measurement

Reconstruct

• Create native CAD geometry
• Repair topology
• Build parametric features

Validate

• Compare CAD to scan data
• Generate inspection reports

Deliver

• Native CAD files
• MBD models
• Updated BOMs
• PLM-ready datasets

This is often called:

• CAD remastering
• Technical data package modernization
• Digital twin creation

For aerospace and defense work today, a strong workflow is typically CATIA, NX, or Creo

‍

Some of our most fun projects are taking someone’s sketch on a napkin, and transforming it into a manufacturable part. Yes, we can turn your sketch, idea, or dream into an engineered CAD file. Our team will go through engineering simulations, Design for Manufacturing (DFM) best practices, and tough calculations to make sure our designed part will work perfectly for you.

Allow our team at CAD/CAM Services to be your on-call engineer. We love going back and forth with inventors and dreamers like you, and our goal is to provide 3D CAD files and 2D manufacturing drawings. With our help, you can start building your dream part, assembly, or product today.

A CAD conversion is when our team of engineers takes your sketch, physical drawing, existing CAD file, 2D CAD file, or idea and transforms it into a professional 2D or 3D CAD file. For instance, you can send us a picture of your legacy drawing, and we can create a 3D CAD model from scratch in your favorite CAD program (like NX, CREO, CATIA, SolidWorks, etc.).

‍

A CAD conversion takes many shapes, and our engineers are able to perform most of the CAD conversions that you can think of. As long as you want high-quality 2D or 3D CAD files, then CAD/CAM Services can help.

We need to know source CAD and target CAD software. Since large quantity orders can be discounted by us you can provide us with the number of parts you need to be converted.

If you tell us the desired purpose of the conversion we can offer you some conversion options. We can also convert your files into vendor-neutral file types (.STEP, .STL, etc,).

Please email us even cell phone photos, and the rough size of what you wish scanned and converted sales@cadcam.org.

You get native Cad Perfect™ files with the full-featured model tree (where applicable, since some file types have no trees), and features can be fully parametric. It all depends on your goals.  We prefer to not translate any files. Our goal is to deliver to you a file that you do not have to touch. Our work is exactly as if you had reproduced that work in-house.

All the CAD file formats are listed on this page but bear in mind that we also work with exotic and legacy CAD systems.  After 31 years of providing CAD Services, we have run into almost any CAD file format.

We support all the modern CAD systems including SolidWorks, Catia, Siemens NX, PTC Creo, Inventor, Revit, AutoCAD, and many others.

Yes, absolutely. We can perform legacy CAD conversions.  Just send us some example files, and what CAD system we need to wind up in, and let us design the best solution for you.We have worked with old Computer Vision tapes, Anvil, and many other 1980’s systems.

Yes, we performed successful conversions from many local or exotic and ancient CAD systems. You can continue the development of old projects in modern software with our help.

Of course, we offer CAD migration services. If you want all the Cad Perfect™ files to comply with your updated company standard, just send us the guidelines and we will make Cad Perfect™ files which are perfect for you!

It is better to ask the following question:

What can you do that a software translator cannot do?

1. Verify files.
2. Update files
3. Fix files
4. Convert the CAD data to native intelligent CAD data with full feature trees.
5. Update data to the current CAD standards.
6. Work in the native PLM systems.
7. Correctly write scripts for this process as needed.

Model-Based Definition (MBD) is a CAD methodology where the 3D CAD model becomes the authoritative source of product definition, replacing or greatly reducing the need for traditional 2D engineering drawings.

What Is Included in an MBD CAD File?

An MBD file contains:

• 3D geometry of the part or assembly
• Dimensions
• Geometric Dimensioning & Tolerancing (GD&T)
• Surface finish requirements
• Material specifications
• Manufacturing notes
• Welding symbols
• Inspection requirements
• Product and Manufacturing Information (PMI)

Instead of looking at a separate drawing, engineers, machinists, quality inspectors, and suppliers can access all required information directly from the 3D model.

Common MBD File Formats

Many CAD systems support MBD:

• CATIA
• Siemens NX
• PTC Creo
• SOLIDWORKS

Typical file formats include:

• Native CAD files (.CATPart, .prt, .sldprt, etc.)
• STEP AP242
• 3D PDF
• JT
• QIF (Quality Information Framework)

Why Companies Use MBD

Benefits include:

1. Reduced engineering documentation costs
2. Faster manufacturing handoff
3. Improved quality and inspection automation
4. Better digital thread integration
5. Support for Industry 4.0 initiatives
6. Less risk of errors caused by outdated drawings

MBD in Aerospace and Defense

MBD is heavily used by organizations such as:

• Boeing
• Lockheed Martin
• Northrop Grumman
• United States Department of Defense

Many defense programs now require suppliers to deliver MBD-compliant datasets instead of traditional drawing packages.

Example

A traditional package might include:

• Part model
• Assembly model
• 10-page drawing package

An MBD package might contain:

• One 3D CAD model
• Embedded dimensions and GD&T
• Manufacturing and inspection annotations

The machinist rotates the model, selects annotations, and programs manufacturing equipment directly from the MBD dataset.

Skills Needed to Become an MBD Expert

If your goal is to become an MBD specialist, focus on:

• CAD software (CATIA, NX, Creo)
• ASME Y14.5 GD&T
• ASME Y14.41 Digital Product Definition Practices
• STEP AP242
• Model-based manufacturing
• Digital thread / digital twin concepts
• Product Lifecycle Management (PLM)
• Quality and inspection workflows

MBD expertise is particularly valuable in aerospace, defense, automotive, medical devices, and industrial equipment industries where companies are transitioning from drawing-centric engineering to fully digital product definitions.

Fill out our quote form, attach your files, or simply send us an email. Tell everything about your project, like the model purpose.

For smaller files < 15 MB you can simply email them to us.  For something larger, just drop them in any number of drop boxes like Dropbox, Google Drive, Microsoft OneDrive and others.  Or if you would like, just contact us for a private, hardened link.

It is fine to use most any time of compression such as  *.zip, *.rar, *.tar, *.7z, *.arc, *.LBR, and even *.iso images.

A direct email is sales@cadcam.org

We also use a hardened OwnCloud web file sharing platform for unlimited file transfers. We provide unique and very private Web Storage Portals, this also supports file syncing for extreme convenience for you. Because so much of our work is DOD or weapons design work, Security – and confidentiality is very important to us.

Yes. NDAs are a common part of our business. All data is yours – not ours, and treated as proprietary data and not for public consumption or use. Probably 70% of our work is under NDA agreements. We can generally get these signed within the day.

It depends on the scope of work:

• 2D drawings – small quantity, normally 48 hours.  We have several customers where they contract to us, keeping 4-8 drafters busy full time.
• 3D models – complexity dependent, but smaller jobs in 2-3 days. Some models we have spent months on.  Again, we have several customers where they contract to us, keeping 6-10 3D CAD designers busy full time.

Simple jobs have a lead time of 48 hours. Larger projects are delivered and invoiced weekly.

Yes, we did back in 2008. We started using Cad Perfect™ back in the early 1990s because all of our customers wanted only real Cad Perfect™ work. Back then the buzz words were terms like machine ready, or DXF Traceover and others.

The problem is, nobody wanted that. They all wanted drawings and models that they did not have to touch. Everybody wanted drawings just as if they hand redrew the work themselves.

Thus, Cad / Cam Services™ was the first company to start offering ONLY Cad Perfect™ work.

Yes we do, and have now for several years. In addition, we also support the industry specific plans as well.

The Presidential Policy Directive 21 (PPD-21) is a Critical Infrastructure Protection and Resilience United States directive that aims to strengthen and secure the country’s critical infrastructure.The goal of this directive is to reduce vulnerabilities, identify and disrupt threats, minimize consequences and hasten response and recovery efforts related to critical infrastructure.

The directive defines resilience as the ability to prepare for and adapt to ever changing conditions, terrorists, and withstand and recover rapidly from disruptions. Resilience includes the ability to withstand and recover from deliberate attacks, accidents, or naturally occurring threats or incidents.

The Department of Homeland Security has identified 16 different infostructures:

1. Chemical Sector,
2. Commercial Facilities Sector,
3. Communications Sector,
4. Critical Manufacturing Sector,
5. Dams Sector,
6. Defense Industrial Base Sector,
7. Emergency Services Sector,
8. Energy Sector,
9. Financial Services Sector,
10. Food and Agriculture Sector,
11. Government Facilities Sector,
12. Healthcare and Public Health Sector,
13. Information Technology Sector,
14. Nuclear Reactors Materials and Waste Sector,
15. Transportation Systems Sector,
16. Water and Wastewater Systems Sector.

This is both Government and private sectors.

If you are in any of these industries, this directive is important to you for many reasons.  Do you know where your critical sections are? Are they well protected? Are there concerns for Hazmat, security clearance requirements, and other concerns?  Can you quickly rebuild what might be lost?

The important part of this means that critical infrastructure must be secure and able to withstand and rapidly recover from all hazards. Achieving this will require integration with the national preparedness system across prevention, protection, mitigation, response, and recovery.

Depending upon when you catch us, yes, we can handle rush jobs. We often work over the holidays, Thanksgiving and even Christmas holidays. If you have a deadline – call us.

For years we have run three shifts of about 30 drafting folks per shift – allowing us to deliver work 3x faster, and seven days a week. Yes, we work 24/7, so you do not have to. The fun never stops here.

For 3D scanning, this is a different question. Because of the common setup work required, at best expect a 48-72 hour turn to be scanned. CAD or simulation services are in addition to that.
