As a 3d object to view ? You can draw an pline with inside outside arcs and extrude, so a solid curved sheet. It is possible to "subtract" a 3d solid shape from this sheet, the issue is that the plug to be used has be arrayed in a circular pattern. A tricky but doable task, the result will hopefully look like what you want, but don't dim the cutouts. This is opposite to what you want, but similar idea, some one else more experienced with solids will probably help. The lettering is extruded through a curved surface.

When you open a dwt it loses its name as a dwt and becomes a dwg, as suggested by @lastknownuser you can store a variable in the dwt using LDATA. A startup lisp can look for that value. ; inside dwt do this once (vlax-ldata-put "DWTS" "DWTNAME" "actualdwtname") ; autoload lisp (if (= (vlax-ldata-get "DWTS" "DWTNAME") nil) (princ "\nNot a dwt") (load "all the lisps here") )

I selected the leader and the mtext and ran the lisp, this is what it came back with. Text 171084.0; error: bad argument type: 2D/3D point: nil Things that may be of note: The leaders have "arrow" set to none. The mtext and leaders were originally a surface elevation callout that was exploded twice, once to become a block reference, and the second time to make a leader and mtext. If I just select the leader and execute the lips it says "0 found"
