This is similar to question posted on 1/12/2007. I am exporting
complex geometry out of solidworks and saving them as
IGES/STEP/ACIS. However, when I reopen the IGES/STEP/ACIS files
with solidworks, I get an error: No solid data in file. I am trying
to find out whether the complexity of the geometry is the problem.
The IGES/ACIS and STEP formats are easier to import into other
software that I am using.
