All of the CatiaV5 models seem to import into ANSYS using metric units, even though the Catia users have their Catia
environment set to an inch system. Why is this?

As per our development, CATIA V5 uses mm as their length unit internally and in their files. We use the data from their file directly. ANSYS does have a scaling command, VLSCALE, which should allow you to change all the volume dimensions. Issuing ALLSEL, /PREP7, CSYS,0,
and then VLSCALE,ALL,,,1/25.4,1/25.4,1/25.4,,1 should rescale the volumes to inch units.
