Admittedly I do not create custom MVB's often. I am attempting to create a custom window tag. (Hexagon rather than diamond...)
In a new drawing, I have set the sscale to 1'-0=1'-0". I inserted the OOTB (AEC 6) window tag, exploded it, and changed the attributes for my needs. I created the custom linework within a 1" sqaure box, blocked it and attributes and all work fine.
What doesn't work is the size. When I selected the "definetag", and entered the insertion point, the block was created, but shrunk. It comes into new drawings at a very samll scale.
What am I missing?
