I received some drawings created in Revit and converted to regular DWG file and something strange happened when I invoke NCOPY function from Express tools set:
I don't see any copied object and nested object not highlighted (see attached etransmit to check it). Actually NCOPY not working at all on these files and in a same time working properly on rest files, created in Autocad
I use acad2013 64bit I checked it on above versions and return the same issue
Probably somebody knows the reason for this issue?
