Working with Unigraphics (UG NX) Made Easy


Unigraphics or NX is one of the world’s most advanced and integrated CAD products developing program. NX offers a huge value for engineering companies of all sizes. It simplifies the design of complex products and speeds up their product launch.

NX software integrates principles based on knowledge, industrial design, geometry, modeling, advanced analysis, graphical simulation, and simultaneous design capabilities. The software has effective hybrid modeling capabilities by integrating feature models based on constraints and clear geometric modeling. In addition to modeling and standard geometry components, it allows the user to design complex free-form shapes, such as aerodynamic surface and variations. It also combines solid and surface-building techniques into a single powerful tool.

Unigraphics is easy to use compared to other software only after you know the basic software operation.

It reduces NC programming and machining time.
Improves finishing, accuracy and quality of the surface.
It reduces production time and errors.
It increases the success rate of a new machine implementation.
It maximizes the use of manufacturing resources.
This software saves time and gives you the right dimension to analyze and simulate the problems. A complex structure can be easily evaluated using this software. That’s why it gives a true picture of all the products that are designed before it’s actually done.

  1. Laws and Law Curve are two ways you can control model parameters in NX CAD. Learn how to use the Law Curve function, and you can control the area of a swept surface using these various methods.
  2.  We all know how to zoom, pan and rotate around models. But what if you want to view a model from inside the model? You can use this method to show a correct perspective view from inside a vehicle, a building, or a ship.
    This technique uses two NX functions – creating a camera and setting the center of rotation. Remember that the camera location and perspective are stored with the camera definition, but not the Rotate Point.
  3. Journal files are important; learn how to get started with Journal files, by taking small steps:
    Record a simple journal
    Edit that journal to increase its capability
    Use provided example journals to cut and paste even more capabilities
    Journals have been around for a long while.
  4. Create a high quality single surface from a boundary of curves or edges with the new Fill Surface command in NX. This command can be extremely helpful when importing data from STEP or IGES and the boundaries are not completely closed.
  5. You can use Rib Command in NX to add a thin-wall rib or rib network to a solid body by extruding an intersecting planar section. Ribs are created based on a planar section of curves. The section can be any combination of curves.

  • A single open curve with no other curves’ endpoint connected
  • A single closed curve or spline
  • Connected curves may be open or closed
  • Y-junctions

Simulate Complex Products with CATIA Product Animation?


When speaking of animated graphics, movies and film clips, it would be futile without mentioning the animation feature of CATIA (Computer-Aided Three-Dimensional Interactive Approach). However, before that, it is imperative that we skim through CATIA and its distinguishable features.

CATIA is a multitude application, which stretches over system engineering, electrical engineering, and product animation. CATIA is one of the global leaders for providing solutions that cater to product specification and end-consumer experience. The application is employed by various corporations in leading countries to come up with solutions and products for consumer benefits. CATIA has the innate ability to customize product and solutions that match the happenings in our daily routine. Their ways are innovative, orthodox but relevant to the contemporary scenario. During the development of the model, the application takes into account the aging experience, architects behind the systems, design engineers and all the stakeholders that help in construing the formation of the digital world.

CATIA delivers the unique ability not only to model any product but to do so in the context of its real-life behavior: design in the age of experience. Systems architects, engineers, designers and all contributors can define, imagine and shape the connected world.

One of the foremost thing that this application entails is that its socio-environmental contribution while developing a structural design. With the help of product animation, one can easily develop a robust 3D reporting dashboard for business analytics, on-time coexisting schema, an alliance with everyone, even remote employees. The product animation experience of CATIA provides an unforgettable experience for both existing and seldom users. CATIA ensures that the design specification, modeling and imitation trait also utilizes the maximum potency of everybody. The application not only ensures that the development of the structural design is well engineered but also visually impactful for those designers, associated with the systems and electrical engineering background.

The end-objective of CATIA is creating an evolutionary process that moves in line with the  organiz

ation’s mission statement, objective and target market. By keeping in mind the consumer behavior, the structural designs are modified accordingly, devoid of the fact how complex and sophisticated is the modification. It is another challenge how CATIA simulates the complexity of the product through graphical animation. The application is on a constant paradigm shift that lays great emphasis on how the firms conceptualize a change, design and execute new products and solutions by constantly imparting acceptable deliverance and incorporating the valuable feedback of end users.

Uses for 3D Scanning and Types of 3D Scanners


Uses for 3D Scanning and Types of 3D Scanners 

Quite simply…anyone who needs a faster, easier way to make…well, ANYTHING!  As long as you have something physical to start with that can be scanned, and there are virtually no limitations as to size, location, or position, as long as you have the right scanner for the job.

Here are some examples:

Hollywood movie makers and video game animators regularly use 3D scanning and 3D printing for characters and special effects.
Hospitals and dental labs use these types scanning devices to create digital models body parts and teeth in order to make perfectly fitting prosthetics and dentures.
Museums and galleries use 3D scanners to make replicas of everything from artifacts and statures to dinosaurs.
Architects and Designers can avoid spatial conflicts when remodeling anything from factories and schools to houses and bridges by using a laser scanner to scan and plot the existing construction, then creating a Building Information Model (BIM) to remodel virtually.

  • Hobbyists of all types use small, inexpensive “hobby” 3D scanners to make everything from teacups to robots.
  • Surveyors use 3D scanning to monitor coastal erosion, slope deterioration, buildings, bridges, power stations, refineries, dams, railway infrastructure, topography and more, depending upon what they’re surveying. If it’s solid…they can scan it.
  • Forensics analysts, whether they are recreating a crime scene or a crash site, 3D scanning helps them determine what happened.

With so many different uses for 3D scanning, it’s not surprising that there are different types of 3D scanners:

Laser scanners

Laser scanners can be hand-held or mounted and can make use of one or more these technologies:  triangulation, time of flight and phase shift.  Through “laser triangulation,” laser scanners calculate the exact shape and size of an object. “Time of flight” is based on the laser light impulse which is sent by a scanner to the scanned object. The distance to the scanned object is calculated according to the time that elapses from the moment of sending the laser light until it is captured by a special sensor in the scanner.  “Phase-based scanning” utilizes a constant beam of laser energy that is emitted from the scanner.  The scanner then measures the phase shift of the returning laser energy to calculate distances.

Regardless of the method, the scanner creates a point cloud on the object, and the 3D laser scanner reconstructs the shape of the object. The colors of the object’s surface can even be determined if color data is also collected. 3D scanners function similar to the way cameras function. However, cameras only capture the X and Y axis, while 3D scanners are able to calculate the Z-axis (distance information) relating to the object as well.  They then produce a high quality, 3D image of the object.

3D White Light Scanners

3D White Light Scanners, also known as structured light scanners use a “white light” source such as halogen or LEDs to project a pattern (like a blanket) of pixels that deforms when it strikes the target surface. A 3D reconstruction of the object is created from measurements based on the deformations of the light pattern. Their operation is based on visible light technology and sensors (mostly CCD cameras). Such cameras make possible to obtain the high precision data used for creating the digital 3d model.  The scanners of this type are often equipped with several sensitive elements.

One of the advantages of white light scanners over laser scanners is that the light emission used for digitizing the object is harmless to the human eye, while laser light can harm human eyes, and care must be taken when using a laser scanner.

Photogrammetric scanners

Photogrammetric scanners are older technology and photogrammetry has been around as long as modern photography.  Its primary use is in mapping and topography.  By comparing multiple photographs, these scanners enable the recovery of the exact positions of surface points, as well as. motion pathways of designated reference points located on any moving object, on its components and in the immediately adjacent environment.  Photogrammetry may employ also use high-speed imaging and remote sensing in order to detect, measure and record complex 2-D and 3-D axis.

By utilizing multiple images of the object the photogrammetry software detects the common points to form a 3D model.

Coordinate-measuring machines (CMMs)

Coordinate measuring machines (CMM) are devices used for measuring the physical geometrical characteristics of an object. Initially, these machines consisted of manual probes that were either manually controlled by an operator or they could be computer controlled. Measurements are defined by a probe attached to the third moving axis of this machine.  Today’s probes may be mechanical, optical, laser, or white light.

Unlike other forms of 3D scanning that are “non-contact” CCMs must touch the scanned object in order to obtain the data about its geometry.  Moreover, this technology is not nearly as accurate as laser white light scanners.

The ROI of Outsourcing CAD

Why outsource your CAD tasks like designing, drafting, 2D conversion, 3D modeling and other activities that your engineers, designers or technical staff usually does? There are two important reasons: (1) cost savings; and (2) scalable workforce. img_offshore-outsourcing-in-simple01.jpg
Scalable CAD Workforce

Let’s face it, work doesn’t come through at a steady, predictable pace. Sometimes you have more design work than you can handle, and other times you’re looking for things to do. The fact is that if all of your CAD technicians are in-house, you need to manage their time and the workflow. This means accounting for errors that may occur if they’re too busy and wasted money that occurs when you have to pay them even though there’s no work for them to do. In either instance, you’re not making the best use of your resources.

One of the advantages of outsourcing some or all of your CAD work to a company that provides contract CAD services is that you have the benefit of a scalable workforce – one that you use as and when you need it, paying only for what you use.

Cost Savings

Outsourcing with an experienced CAD services company can save as much as 50% of the cost for in-house draftsmen while assuring high quality, accurate drawings, which minimizes the risk of onsite issues. This cost savings is as a result of these benefits:

Scalable workforce – pay only for what you use, when you use it
Up-front, transparent costs – no surprises
Increased drawing output with a lower cost per drawing
Eliminate hiring and layoff costs when coping with fluctuating workloads
Minimize in-house training needs
Reduce your investment in in-house computers and software
Reduce mark-up times by using the symbol libraries that a good CAD services company maintains
Finding the Right Company

The right CAD service company can provide economical and scalable resources that will you’re your company manage varying CAD drafting and CAD conversion workflow. Most organizations have seasonal or economic fluxes in their workflow which can result in the need to hire additional CAD technicians during busy seasons and lay-off during slower seasons. This shifting CAD technician population can result in difficulties in maintaining standards of drawings, continuity of workflow and can actually increase your organization’s costs.

CAD services outsourcing with a reliable CAD services contract source can provide cost and savings benefits, improve standards and quality of drawings, help you maintain flexibility in response to changing conditions, and maximize workflows.

A reliable CAD Services contract provider must maintain consistently high standards of drawings or they will soon find themselves with no customers. We like the Cad Perfect™ designation, which just about says it all. Cad Perfect™ accuracy reduces onsite issues.

CAD Services Flexibility

Outsourcing CAD requirements offer any company greater flexibility in responding to changing conditions. Whether you have one large project or fluctuating workloads, a reliable CAD services company should be able to work with you in a way that suits you, whether you want to outsource all of your drawings, drafting and conversion work on an ongoing basis, or only some of your work on an occasional basis.

Large Format Scanning | Small Format Scanning | Large and Small Scanning


CAD/CAM Services, Inc. uses the latest in large format scanners. These allow the scanning of up to 56″ wide media, with 54″ wide image width. We can scan up to 2,400 dpi and support both 256 grayscale (often used in Aerial Photography), and 42-bit high-speed color, with a thickness of up to .5″.Our scanners directly support most any raster file format. Including all flavors of *.tiff, *.jpg, *.PDF, and most others.

Typically the CAD files we provide include: AutoCAD .DWG, Intergraph .DGN, ERSI’s ArcInfo .001 coverage files. Raster scans might include .TIF (any flavor), CALS .GP4, .BMP, .PCX, and .JPEG for color and gray scale.

Small Format Scanner

CAD/CAM Services, Inc. uses Scan-Optics for our small format scanning. These $200,000 scanners are the largest, fastest, most accurate scanners on the market today. They provide the speed and turnaround our client’s demand, with the highest image quality possible.

The most common raster files are compressed *.tiff group 4. Proper indexing is always our largest concern for this type of scanning. We have extensive experience with Interactive Electronic Technical Manuals (IETM) and other such complex file systems and formats.

VRS – In 1998 Kofax introduced one of the industries’ best image enhancement tools we have seen to date. VRS technically scans an image in grayscale and automatically processes this for its image quality. VRS is smart enough to strip out dark and color backgrounds and still leave the text intact, producing a standard bitonal *.tiff gp4 image. You will only see this significant technology in the ‘better’ production scanners today. All of our paper scanners now support this technique.

The most common raster files are compressed *.Tiff group 4. Proper indexing is always our largest concern for this type of scanning.

Microfiche & Microfilm

Mekal produces some of the finest film scanners available. We use these and they support 16 mm, 35 mm, and microfiche. They support 200 or 400 dpi and both black/white and grayscale.

Aperture Cards

We use both the high-end Photo Matrix and Ideal/Contex aperture card scanners. These support 100-400 dpi scanning in both black/white and grayscale. We scan in excess of 250,000 cards per year.

Scanning Services

CAD/CAM SERVICES comes from a different perspective than most scanning firms. Because so much of our business involves CAD Conversion, we have to be able to see the images at their maximum potential. If we can’t see the image, we can’t convert it. Simply put, this is why we are forced to buy the best scanners on the market today. We simply can’t afford anything less than perfect image quality for our scanning and conversion clients.

It is not uncommon in our large format scanning to scan the same large format engineering drawing 4-8 times!

On bulk film scanning projects we work with you to determine how much Q/C is needed. Do you wish us to individually Q/C each and every image – or maybe every 3-5 images would be sufficient?

Some comments on Bitonal -vs- Gray Scale

This can be a tough question. Samples are the only way to truly answer this. Here are some factors to consider: 1) How good is good? 2) Grayscale will almost always look more like the original image. 3) Your human eye sees in color and Gray Scale, and your eye is better suited to ‘take out’ unneeded information. 4) Not all high-speed scanners can scan grayscale. 5) Grayscale scanning is 2-3 times slower to scan, and therefore more expensive. 6) The image size for Grayscale is 2-3x larger.

How do we scan for our own work? Generally, for full-size engineering drawings for raster-to-vector (also known as r 2 v, r to v, r2v) work we almost exclusively use Grayscale scanning at 300 dpi. Each project often uses different techniques and software conversion products and methodology for each document type. That is why we use software from Consistent Software (Wise Image), GTX (RasterCAD), Softelec (VP Studio), Hitachi (Tracer) and our own custom written and developed software. I.e.: Large format and aperture cards are often used in R/V projects, where the film is often used only for archival.

Image prep

This is often a very misunderstood concept. Somebody – whether it be your company or our firm – will need to often ‘prep’ your documents to get them ready to scan. For example, somebody will need to remove staples, unfold any sheets, possibly reorder them, and many other conditions. Think of it this way, when scanning small format paper, somebody must prepare the documents just as if you were going to run them through your document feeder at your copy machine. Which leads us to our next step indexing.


How are you going to find the images after they are scanned? Maybe in engineering drawings, the drawing number in the title block is sufficient? Don’t skimp here. Pay a little more upfront and get them ‘over indexed’. Why does a person put all that information in a title block? Why are drawings stored separate folders? It is there for a reason.

CAD/CAM Services can even go into each image and manually pull out any piece of information required. This data is often delivered in some type of database (often Microsoft Access) and imported directly into a document management system.

Document Destruction

Your secure documents can be professionally destroyed with our production shredding equipment. All documents are cross shredded to ensure complete destruction. We use the Federal Governments method for complete and secure document destruction.

Scanned images can be delivered via FTP, CD, 8 mm tape, and Zip drives.
