    Sketch points over Reference points, not coinciding

    John Christensen

      I'm trying to use reference points created along a curve to place various sketch segments and sketch points.  I can get the reference points located, and also any number of sketch types located using the same points, or so it would seem, (lines, arcs, etc), yet the two do not match.

      The reference points are accurate.

      The sketch points are not.

      Yet they should be because they are supposedly using the same points.  One array gets the refpoints, same array creates the sketchpoints.

      If I could get past this part, there are number of other applications where I could use this format, if only it were accurate.

       

       

       

      'Precondition:
      '   1)part is open, close all sketches

      '   2)pick on a spline from either an edge or sketch


      'Post condition:
      '   1) reference points are located along curve
      '   2) sketch points are located directly over reference points
      '   3) currently there is a locating error for sketchpoint locations ??
