Shoulders and narrow ledges don't produce tool paths on Origin:
If a ledge is narrower than the cutter installed + the pocketing protective boundary tool paths will not be produced. On tool solutions include changing to a narrower cutter, and or changing the pocket to an inside cut.
If that does not solve the problem open the svg in a 2d vector editing package ( Illustrator or Inkscape ) and manipulate the pocket shape making it large enough to accommodate the cutter you wish to use.
I cant export lines.
The default "single solid body" export mode analyzes solid shapes, lines are not considered.
To add lines ( for online cuts or guides ) export the single solid body as you usually would, then activate the advanced button and export the sketch containing the lines.
First opening the single solid body svg in a 2d vector editing package, then copying and aligning the exported lines svg file will enable you to delete the unneeded geometry and color code the remaining lines as you wish ( stroke = blue for guide, stroke = grey for cut on line. )
