Conversion from SOLIDWORKS to Unigraphics is not supported yet :(

SOLIDWORKS is a modeling CAD and CAE program by Dassault Systemes which runs on Windows. It is built on Parasolid kernel. SOLIDWORKS user base covers a very wide range of manufacturing market segments, such as aerospace, transportation, electronics, machinery, medical, etc.

SOLIDWORKS users are capable of drawing 2D and 3D sketches, creating models and assemblies, adding notes, dimensions and tolerances.

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.
