I'm trying to create blocks but lines, polylines, circles, holes, and fasteners won't be included in the working set and when I list the elements it gives "occurrence path= /element name (identifier)" at the end of the description. Element name can be anything eg polylines, circles etc. Identifier can be alpha/numeric eg (438B). If I copy the offending elements they may lose the "occurance path" identifier. This is very frustrating and is severely slowing my work.
