We are cleaning up our block library drawings and came across a stubborn
drawing that will not purge out the following. A block named GENAXEH and dimension styles AM_ANSI, AM_ANSI$SF and AM_ANSI$SH.
So far we tried purge all, wblocking the drawing, dxfout and dxfin, copyclip the drawing into a new drawing. All methods tried still have the block and dimstyles in the new drawing.
I just found out that even if I draw just a new line and copyclip it into a new drawing, it also carried over those dimstyles. Any ideas or experience with this issue would be appreciated.
