AR-CAD LLC provides motion simulation, engineering and graphics software for companies using CAD (computer-aided design) systems in their operations.
Their software products can be stand-alone or work as add-ins or customizations in other computer-aided design programs like AutoCAD, Inventor, Solidworks, Alibre or SpaceClaim. The company specializes in developing motion add-ins, which allow customers to create machines or mechanical processes within their CAD systems and see visualizations of forces and motions in play based on physics. Users can then experiment with many configurations and spot problems before actual fabrication.
A 20-Year Difference-Maker
AR-CAD has relied on the combined power and simplicity of Cincom® VisualWorks® as its technical advantage since 1991. The ompany co-founder began using VisualWorks that year as the basis for creating an object-oriented dynamics simulator in computer-aided design. The advantage was immediately obvious.
AR-CAD developed its own CAD offering, “freeCAD: 3D CAD with Motion Simulation,” which had a graphical user interface. In 2005, that product would be adapted as a motion add-in for Alibre CAD. In 2010, a motion add-in was crafted for Inventor CAD, and one was also completed for Solidworks CAD. Additional advances were made in creating a motion add-in for SpaceClaim CAD, which also included other customized add-ins developed by AR-CAD.
A die automation CAD was also created with VisualWorks. The code is open source at http://askoh.com/stcad.
3D Multibody Dynamics is a complicated field. There are only about five software options available, and they were developed by large teams of programmers using Fortran or C++. I was able to develop one by myself using VisualWorks entirely.
