Solution
You can usually find 3D CAD models of NI hardware on the
dimensional drawings page. This page provides documents in a variety of file formats that are compatible with most commercial third-party CAD software.
Please note that while the 2D dimensional drawings are available for most parts numbers, the 3D models are not always available. If this is the case and the product you are looking for does not have a 3D model, you will need to create your own 3D model using your preferred third-party CAD software. The 2D dimensional drawings should contain all the information you need to create the 3D model.
