units conversion - holes don't work!

Guys,

I am modelling a part in inches, and this part has tapped holes sized
2-56unc. Now I want to convert the units to metric to fit into my assembly.
Trouble is the holes fail. Is this because the holes are 2-56unc? Why can't
I have 2-56unc holes in a metric model? Any ideas?

I got it half working now. Seems it lost the reference to a hole axis during
the units conversion. I redefined it, and can now see some lines of the hole
(not all) in wireframe in the correct location, but in shaded mode the hole
surfaces disappear and I can only see the axis. This has to be a bug.

Check your accuracy, you may need to go much smaller than the default, This
worked for me when I had a similar problem.

 

I don't do it very often but we have a mapkey for changing a drawing to
meteric. I think it just loads a different drawing DTL file and
refreshes.
