Is there a good example 3dm file with ON_InstanceDefinitions in it? I’m looking at working on my own version of the cmdTestSirian.cpp example code posted a few days ago, but I don’t know of 3dm files to try it on!
On the plus side: I see instance references!
On the ugly side: My current code crashes on this file!
Gives me something to work on, anyway, thank you!
