Conversion from Simlab Composer to Unigraphics is not supported yet :(

Simlab Composer is a visualization and VR creation software by SimLab Soft. It is applied in creating renders, building VR scenes, and running simulations.

Simlab Composer provides users with a possibility to import, visualize, render, and animate 3D CAD models, share and collaborate, automate and improve visualization and simulation workflows.

Unigraphics is a former name for Siemens NX, an advanced CAD/CAM/CAE software application suite. However, veterans are still using the Unigraphics name.

In 2002, the new version of Siemens Unigraphics, merged with I-DEAS software, was released and called NX, which means "Next Generation". In fact, it was the last version of the software released under the Unigraphics name. All further releases became known as NX. So the addition of I-DEAS functionality to the core code of the Unigraphics has become the basis of the existing NX product line.

Siemens NX / Unigraphics use a .prt extension, which contains 3D CAD parts.
