Conversion from I-DEAS to PRC is not supported yet :(

I-DEAS (Integrated Design and Engineering Analysis Software) is a computer-aided design software package. It was originally produced by SDRC in 1982. I-DEAS was used primarily in the automotive industry, most notably by Ford Motor Company and by General Motors. Now it is owned by Siemens PLM Software. Many I-DEAS technologies formed the basis of the NX system.

PRC (Product Representation Compact) is a 3D file format that can be used to embed 3D data in a PDF file.

This highly compressed format facilitates the storage of different representations of a 3D model. For example, you can save only a visual representation that consists of polygons (a tessellation), or you can save the model's exact geometry (B-rep data). Varying levels of compression can be applied to the 3D CAD data when it is converted to the PRC format using Adobe Acrobat 3D.
