Conversion from CADMATIC to Unigraphics is not supported yet :(

CADMATIC is a leading developer of digital and intelligent 3D-based design, engineering and information management software solutions for the marine and plant industries. CADMATIC solutions (CADMATIC Marine and CADMATIC Plant) are used for all kinds of ship, offshore and process plant constructions, ranging from luxury yachts to the biggest cruise vessels and offshore platforms in the world, and from food and pharmaceutical projects to the biggest power, chemical, oil & gas and pulp & paper projects.

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.
