With the CATIA part design application, users can transform rough sketches into extremely accurate 3D mechanical parts.  This software offers a variety of efficient design features, which in turn allows us to tackle a range of projects. From simply assembly components to advanced gears and drives, CATIA gives us the ability to accommodate the specifications of clients at any scale. Here is a brief rundown of how we utilize part modeling in CATIA.  

Getting Started With Part Modeling in CATIA

CATIA’s feature set covers a range of tools that correspond roughly to the functionalities of other leading CAD software. Here is what users can expect from CATIA.


CATIA Part Modeling Features

  • Creating a Pad. In many other applications,you will find this feature under the EXTRUDE command, but when part modeling in CATIA the PAD option is used to extrude a 2D sketch into a third dimension. The part design software gives us the ability to set limits for extrusions and to choose which direction the sketch is extruded.


  • Creating Multi-Pads. This option allows us to extrude multiple profiles in the same sketch with individual extrusion values set for each profile. However, profiles used for Multi-pad extrusions cannot intersect with each other. The intuitive part design interface allows you to select and adjust each profile minutely for added convenience.


  • Create a Pocket. The Pocket command lets us remove material from an existing 3D model, thus creating an effective pocket of space in the design e.g. creating a cylindrical hole in a solid 3D block. Just as when part modeling in CATIA for an extrusion, the tool allows you to set the direction, depth, and dimensions of the pocket. Like the PAD option, the Pocket command will allow you to adjust these qualities in multiple profiles across a single sketch.


  • Create a Shaft. As the name suggests, this tool is used primarily for creating shaft-like parts that revolve around a central axis. If the axis is already included in the sketch then you will not have to select an additional axis for modeling. While you can create shafts from sketches featuring multiple profiles, the profiles will all need to be extruded in the same direction from the axis. CATIA also offers options for creating grooves, threaded holes, and standard-shaped holes.


  • Create a Rib. This part modeling tool is used to extrude material along a guided curve. In other design software, you may see this feature pop up under the SWEEP option.


  • With the assembly tool, you can combine two or more part models to create a completed assembly. We can use either the top-down or bottom-up approach to designing assemblies in this environment. With the latter option, all parts are created separately and mated together, while in the latter the entire design structure is created as one whole.
