Hope to have your comments on whether there is anything wrong with my use of X-Form in the example below. Thanks!
1. "Section" is a 2-segment degree-3 spline with the knot controlled by the point "x%"
2. "Starting Surface" is created from two curves: "Section" and "Guide".
3. The two patches of "Starting Surface" can be adjusted by "x%".
x% = 40%
x% = 50%4. X-Form is created, without any modification to "Starting Surface".
x% = 50%5. When x% is changed to 40%, the X-Form surface patches do NOT follow!
x% = 40%
