I have dowloaded electronic component 3D CAD models from "3D Control Central", "Snap EDA" and "Ultra Librarian". I use them in the Altium Designer.
I curious to know what are the free relatively simple tools that can be used to create these 3D CAD models? I usually download a .STEP file of the model and then put it into Altium Designer using the 3D Body Placement feature.
On the 3D content central, the models are available in a lot of different formats. These are IFC 2x3 (*.ifc), IGES (*.igs), Inventor (*.sat), IronCAD (*.sat), JPEG Files (*.jpg), Mechanical Desktop (*.sat),
Parasolid Binary (*.x_b), Parasolid Text (*.x_t), Pro/E Part/Assembly (*.prt), Revit (*.sat), SDRC I-DEAS (*.step), SolidEdge (*.x_t), STEP (*.step), STL (*.stl), TIFF (*.tif), Unigraphics (*.x_t), VDA (*.vda), VRML (*.wrl) and Edrawing Part/Assembly (*.eprt). These are very numerous.
What I often need to do is to change some aspect of a 3D model downloaded from these websites. This could be required to create a new component's model or to make correction to an existing model.
