Just last week I opened our AC 12 template and there seems to be a corruption in the .pmk file we use as our title block. All the curved lines now have arrow-heads. When I open the original in Plotmaker, everything is fine.
If I import a new copy of the file, it comes in with the arrows- same thing when I tried saving a copy of the plotmaker file and importing it.
I don't know where the bug is- with plotmaker or with ArchiCad.
Any ideas????
