Conversion from KOMPAS-3D to PRT is not supported yet :(

KOMPAS-3D is a flexible 3D modeling system that allows creating models by several methods, including the following ones:

Bottom-up modeling using finished components. Top-down modeling by designing components to match specific designs. Modeling based on layout drawings, such as kinematic diagrams. Or any combination of these modeling methods. These approaches allow creating editable associative models easily.

The KOMPAS-3D system has powerful functions for managing projects of thousands of sub-assemblies, parts, and standard library products. It supports all the capabilities of 3D solids and surface modeling that have become the standard among medium-level CAD/CAM programs.

A PRT format is used to store components of 3D CAD models. It may contain lines, surfaces, textures, dimensions, and metadata.

The .prt extension is mostly associated with the Siemens NX Part (PRT) file type as an acronym for "part". PRT files may be exported to various standard CAD and 3D modeling formats (e.g. OBJ and STL) in addition to being utilized natively in Siemens NX.

The PRT file is also a part created by PTC Creo Parametric 3D software. In PTC Creo, project part files can be combined in a single assembly file with an ASM extension.

Despite the same extension name different CAD software produce PRT files differently, i.e. PRT files produced with Creo are not the same as PRT files generated from NX.

The PRT extension is also compatible with Dassault Systèmes SOLIDWORKS.
