I have a survey drawing that I am working with that is not allowing ACAD2k to Copy & Paste.
What I have found is that some objects have Te DXF codes pairs in a strange order.
This may be nothing to do with the problem.
I was able to use Express tools 'Copy To Layer' to create new objects, so that means we
can create our own Copy & Paste Routine.
Also to get around the WBLOCK not working & use my EntityMaker.lsp which creates a lisp
file that when run will create the copies of the objects.
In this particular drawing I can Copy & Paste the New objects, but in the Test.DWG posted
in this thread even the new objects I created could not use Copy & Paste.
Just some of my observations.
