I have been noticed a difference between version Rhino 8.8 and Version 8.15 when it comes to import blockinstances from a dwg-file. When my college imports a blockinstance with UserText on the BlockInstance fro a dwg using Version 8.8, the Usertext will be imported just fine. When I import the same file with Version 8.15 the UserText on the blockinstance is missing completely.
No, there should be a bunch of Usertext entries. I am not in the office today to test with the version 8.8. Tomorrow I can tell you exacly which Usertext is missing.
If the Autosad Attribute doesn’t have a default it isn’t being processed on the import. It’s (expression) there in the block but doesn’t have the UserText to read.
