Solid 3D models, available from Omnetics Connector Corp., have been created as STEP Files (.stp) to be inserted\imported into a variety of different CAD programs (e.g. ProE, Solidworks, Inventor). By having models available in the design stage, engineers and designers don’t have to create them, thus saving a lot of time and effort. It will also decrease "guessing" errors because the 3-D models are created to size with all available termination options. Once imported, users can move and manipulate them within the design and position them where needed to check for size constraints.
