Stitched up a surface model in MDT2004 because it would not stitch
up in Inventor (one surface was twisted, amoung other problems).
So, once I had a Part created in MDT, I thought the best way to translate
it would be directly opening the MDT file. Opened fine, but I could not
pick any of the features to mate against. So rather than inserting numerous
workplanes, axes, etc, I tried using Step to import the file without healing,
stitch or promote options and Inventor now recognises flat surfaces as flat,
cylindrical holes as holes, etc.
So why does Inventor not see these flat surfaces and holes as such when
directly opening MDT files? THis may of course only be a problem with
imported geometry and not native MDT geometry, but still, one may wish
to keep in mind that STEP from MDT to IV8 may work better in these
non-native cases.
