Ok, now were getting somewhere!

The *.Obj from Hex file does get confused, however it is easily fixed in C5's Vertex modeller. However I cannot explain how a Hex saved *.car file will not open in C5 Pro. As mentioned earlier, files saved as 3DS and Amapi files have not caused any problems when imported into C5 Pro.

has anyone else foud a problem between file transfer of a *.car file from Hexagon into Carrara?

Many Thanks to Zikeo
