I have run into a small issue when importing Revit-blocks into Rhino via the dwg-export in Revit.
The issue being that an ID number appears in the block definition, when imported into Rhino, although the very same block does not have that ID number in Revit. It is problematic, because the block in Revit belongs to one big family and that family is split up into smaller groups, when imported into Rhino. Ultimately this results in a lot of unnecessary extra work, as I cannot seem to merge the blocks in the BlockManager in Rhino. Thus I have to manually exchange all the groups of blocks apart from one group in the family and then make copies from that group, so I end up with just one family in Rhino, when applying block edits.
Can this really be the case or am I missing something here?
