need to get side points of path object

armen

Hi All,

 

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.

 

Thanks,

Armen

  • Hi Andrew,

     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)
        leftEdge=nil
        rightEdge=nil
        ; 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(rodObj~>endLeftLast leftEdge)
        rightEdge=cons(rodObj~>endRightLast rightEdge)
        foreach(coord rightEdge
            leftEdge = cons(coord leftEdge)
        )
        leftEdge
        )
    )

     

    Thanks again,
