I am new to Blender and I am looking for this information: Length of path or how it might be called. I want to create a ball with a rope twisted around it, and the length of the rope should stay the same. But if I take a path/curve and twist it, it changes it’s length. I found out, that in Blender 2.49 there was a “PathLen” button, and clicking on it revealed the length of the path, but I cannot find this one anymore in Blender 2.74. The information “length” is not important to me, it is the length I want to preserve! On a blender programming site I found use_preserve_length - is it possible to tell a structure to keep it’s length while bending it??
