For example, freeform modelers allow the user to “sculpt” objects out of a digital base mesh just as a sculptor would use clay, while solid modelers start with a blank workspace, and users add and subtract geometries to create new features. It is difficult to speak on every type of CAD software, as some programs specialize in application-specific directions. Reverse-engineering existing products using imported real-world 3D scans.Determining clearance issues/motion of an assembly.as well as generative-based design for optimization Simulating stress, thermals, aerodynamics, etc.Documenting databases of common/industry-standard part models.Managing assemblies by cataloging a design’s bill of materials (BOM).Creating renderings for products in development.Creating and preparing designs for AM applications (3D printing).CAD finds uses in nearly every industry now and is used to perform such tasks as: Thanks to powerful computers with CAD programs installed, users only need electrical power to create models that are more accurate and more detailed - all made in less time than with traditional methods. CAD software was invented to increase design productivity, as previous design techniques required lots of fabrication using physical materials. Image credit: Gorodenkoff/ What is CAD/CAM Software?ĬAD software allows users to plan and digitally build the geometry, size, and framework of a project as well as define its material and functional properties. There are numerous types of CAD/CAM software available that pair well with 3D printing technology, so this article will help those interested in CAD software find the best ones for 3D printing applications. With the recent popularity of additive manufacturing (AM) technology, CAD software is now more valuable than ever as a means of planning and printing models using 3D printers. CAD software allows users to digitally represent 3-dimensional projects, and this software is incredibly versatile as a design, analysis, and manufacturing tool.
