Hello, If you need a segment starting from (Xa, Ya, Za) and ending to (Xb, Yb, Zb), then use [curve 2] and set coordinates with two lists of three elements. With this solution, you needn't [rotateXYZ] or [shearXY] objects and can make your segment growing from nothing to the desired length. Have a look at [curve] object. ++ Jack
