I set 27 points and snap to them in exact same order to create curves from degree 1 to 11:
then I moved same control point for each curve by exactly the same movement:
Now I want to intersect each couple of curves with identical degrees (intersect the two with degree one; then intersect the two with degree two; then intersect the two with degree three and so on until intersect the two with degree eleven)
Generally when I create a copy of curve and move just one control point of the copied version, and then intersect the curve with its’ modified version, I supposed to see witch parts of the curve remains the same an witch parts change under the influence of that one control point: I supposed to see the range of influence of control points; ok?!
But it doesn’t work! I don’t know why but I can show you one example!
I considered post selecting and pre selection and it makes no difference!
at the end:
- Is my approach good enough toward Exploring the range of influence of control points
- What’s wrong whit intersection command??
