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

nTopology is a versatile, industry-leading data preparation and STL editor software for Additive Manufacturing that allows you to convert files to STL, repair errors, edit your design and prepare your build platform.

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.
