3DSMax Script for Moving Selected Shapes Vertices , Similar to Trim-Extend Behavior .
UPDATE 1 :
- Keep Shape Pivot in its Position .
- Make each Vertex Move on its Segment Direction .
UPDATE 2 :
- Tangents are not Moving with the Vertices , Fixed .
NOTE : the Script still not Perfect on curved splines , (the result not like real Trim or Extend) .
UPDATE 3 :
- Add another script (Spline Extend-Trim - No Grid.mse) , same as previous but without creating Helper Grid .
