File Formats DRD Technology Can Read and Write 

We can take CAD models in a wide variety of formats, improve and/or repair the 3D geometry, if necessary, and then write it out in the format that our customer needs. The table directly below summarizes our capabilities in this area.

File Formats that DRD Can Accept		DRD's Geometry Transfer, Repair and Manipulation Tools		File Formats that DRD Can Create
ANSYS		ANSYS		ANSYS
Pro/ENGINEER		DesignModeler		Pro/ENGINEER
SolidWorks		Pro/ENGINEER		SolidWorks

There is a good chance that we have the same CAD system that you use since we have Pro/ENGINEER, SolidWorks, SpaceClaim, and UNIGRAPHICS. If we use your CAD system we may be able to deliver back to you the optimized design in the intelligent and parametric format of your CAD system. In any case, we can deliver to you an optimized or improved design.

If you don't have one of DRD's four CAD systems, there is still a good chance that we can successfully use your CAD system's geometry to make an ANSYS finite element model. Most of the PC based mid-range CAD systems are based on the Parasolid or ACIS geometry engines, and we have very good tools for working with geometry from these CAD systems. The following table may help you understand how DRD might work with geometry from your CAD system.
