Convert A3D to STEP

Amapi 3D format (.a3d) is somewhat old and the program itself is discontinued for years so you will not find many current programs that still support this particular file type. Nonetheless with the help of some dedicated converters like 3D Object Converter it should be possible to export a3d files to something else, for example to the STEP product data format (.stp, .step) via a3d to step conversion.
