I am running AutoCAD 2012 and wanted to use a lisp program I wrote in 2011 to convert polyface meshes into 3D solids. My code correctly selects the polyface mesh objects and runs the meshsmooth command, but the mesh is not being converted. I can manually convert the mesh, but the lisp will not do it for me. The specific line of code I am having trouble with is as follows:
(command "_MESHSMOOTH" (ssget "_X" '((0 . "POLYLINE"))) "")
AutoCAD's command line output looks correct:
Command: (command "_MESHSMOOTH" (ssget "_X" '((0 . "POLYLINE"))) "")
_MESHSMOOTH
Select objects to convert: 1 found
Select objects to convert:
Command: nil
If I take out the last set of double quotes (shown below) and confirm the selection manually, it also works.
(command "_MESHSMOOTH" (ssget "_X" '((0 . "POLYLINE"))))
Can anyone duplicate my error on their machine? I have provided a polyface mesh sample
