Figure Library Symbols Not Visible When Placed on a Drawing

Issue: Symbols from the Figure Libraries ‘disappear’, figures do not insert when inserted into a drawing, only the center part appears OR only the outer ring appears.  This could occur when copying entities from one drawing to another, and some or all of the entities are not visible when pasted into the target drawing.

Solution: Set the layer that the figure is on to visible.  Simplest way is to turn all layers so all entities are visible by going to Modes, select Design_Mode or All Layers On:
