Can you please help to get path object's side points via SKILL, without using dbConvertPathToPolygon()?
As far as I know, dbConvertPathToPolygon() is desctructive and this task should be done without damaging the layout design.
Creating copy of design is also not preferred as there are many cells to be scanned and performance will highly slow down.
One way to do this would be to use rodId=rodNameShape(?shapeId pathId). Then you can use the various handles on the ROD object to find the coordinates of the left or right sides, say.
I have done similar thing but for a different purpose so I am sure you can also use this method.
You can by skill draw 2 new paths whose centerline is exaclty on the side edges of the original path.
using leCreatePath use the pointlist from the original path and give an offset value of + and - halfwidth of the original path.
you can then return the pointlist of the newly created paths before deleting them. You can then return the pointlist as 2 separate sets or combine them as if it is describing a closed polygon.
I hope it helps.

Sorry for late response, just had chance to switch to this project again.
Thanks a lot for help with rod objects and the script you've sent via support service.
It helped me much to build the procedure collecting all edge cooridnates of path object.
For future reference, I'm copying it here:
procedure( GetPathPoints( pathId )
let( (rodObj leftEdge rightEdge)
rodObj = rodGetObj(pathId) || rodNameShape(?shapeId pathId)
; add the start of each segment
for(seg 0 rodObj~>numSegments-1
leftEdge = cons(rodGetHandle(rodObj sprintf(nil "startLeft%d" seg)) leftEdge)
rightEdge= cons(rodGetHandle(rodObj sprintf(nil "startRight%d" seg)) rightEdge)
) ; for
; add the last segment
leftEdge = cons(coord leftEdge)
In reply to lrl12skdev:
I liked your idea and the approach. The only thing I can't use it this time is that I should deal with design on edit mode while I need to get all working on read-only design too.
Anyway the approach is really creative and can be used in other project I'm working on.
