PTC offers a Direct Interface with Modeling to import / export 3D Data from Modeling / ProEngineer. this is based on the neutral file format. Additionally - since Version 16.50 - Modeling offers to store ProEngineer data (.g / .g.zip) files to be loaded into ProEngineer. And this Interface will be enhanced with CoCreate 17.0 which will offer you a 3D data interface to and from ProEngineer. you may contact your Sales team to get more details on this new function. 2D - DXF/DWG or MI Data.
