Re: 3d model
Bala, Simplified Solutions Inc has an IDF_2_3D STEP model service.This gives the Electrical Engineer access to an MCAD tool.
As part of that service, they provide a FREE 3D PDF file. This might be what you can use.
They also sell a STEP Model that can be imported into any MCAD tool.
Finally, you also have the option to get a board ...
