CAD Conversion Tools

VTube imports STEP and IGES file formats. They are universally supported by all solid model CAD packages. However, in some cases, you may not have access to STEP or IGES files. To convert from other CAD formats to STEP, we have tested and recommend the following program.



The premium version of 3D-Tool includes a converter that converts the native models to standard file formats like STEP. The program is also excellent for measuring any geometry available in the model.

At least these formats can be converted:
