Single line font for engraving

Question asked by Mark Olsen on Sep 16, 2015
Latest reply on Jan 8, 2018 by Doug Seibel

Solidworks added a new single line font a few versions back.  Unfortunately, there is no way to project said sketch onto a non planar surface (at least that I know of).  So I created a macro to do it.  It requires a sketch with the lettering in it, and the lettering must be 'dissolved'.   Select the sketch, and all faces to project onto, run the macro and a 3D sketch on the faces is created.  It does work, but it's really slow.  Anyone have any ideas on how to make it faster?

 

Thanks,

Mark

' Preconditions:
'   A 2D sketch and one or more faces must be selected (in that order)
'   The sketch must contain any sketch entities except blocks
'       Note: If sketch plane intersects any selected face, output is
'           unpredictable (especially if sketch segments intersect face).
'
' Postconditions:
'   A 3D sketch is created with each of the segments in the 2D sketch
'       projected onto the selected faces.  The 3D sketch is completely
'       unconstrained.

BTW, anyone know how to post code so that the formatting and coloring doesn't get messed up?
