The .3dm files I save with the trial version 4.0 Moi will not open in my licensed version 2.0 Moi. Will they open after the trial?

Hi courter,

No, you will have the same behavior after the trial as you currently have.

The issue is that MoI v4 by default will write a Rhino v5 3dm file version. That's so it can support the new dimension entities and also have 64-bit chunk sizes so the file size isn't limited to 2GB.

You can modify this in moi.ini , go to Options > General > "Edit .ini file" button, and in moi.ini set:

[3DM]
Version=4

That will change it to write Rhino v4 3dm files instead of Rhino v5 3dm files (unless you have any dimension/annotation objects in the file) which will then open up in Moi v2 ok.
