Hi Paul, yeah there's a newer version that doesn't use the ActiveX Scripting.FileSystemObject, get the one that says that it's for the Mac here:
http://moi3d.com/forum/messages.php?webtag=MOI&msg=5124.2

That one uses MoI's cross-platform functions for reading the file and that one should work on both Mac and Windows v4. I think that older version may only work on MoI v1 and v2.

Thank You Michael,
that ist the solution. I wasn't aware that the OSX version is also the one for Windows.

By the way: I tested the DXF-Layers -> MIO Styles function in the new V4-Beta, it it works well in my tests until now. Thank you also for that feature.

Best Regards, Paul

PS: I found some problems in Boolean Difference with some Objects (they should do, but they don't), also there are some request for shells and offset-functions, as I am trying to construct the fuslage of my plane. I will do that in another forum-entry soon.
