Unconstrain spline from plane
Unconstrain spline from plane
(OP)
hello.
If I've created a spline from the sketch environment.
Now the spline is constrained to that sketch plane.
How can I move any of its points out of that plane?
Or how can I remove that constrain to the plane?
Could you also explain me the difference between normal and perpendicular to the curve, please?
regards

RE: Unconstrain spline from plane
However, if you can sketch, in two perpendicular planes (they don't actually have to be normal to each other, just that it's easier to see what you're doing if they are) what the projected shapes would be, as I've done in the attached example, you can then create a single 3D curve by 'marrying' them together using the 'Curve by Combined Projection' method. Note that the new 3D curve will be associatively linked to the two planar (sketched) curves.

The resulting curve might have a "knot point explosion".
In Johns example, the 2 sketched curves are both degree 3 and 4 segments. / 7 poles
The combined curve is degree 3 but 29 segments / 60 poles.

I already knew that option but I think it's not what I'm loking for.
Who would you modify the projected spline curve points without editing the other two?
What I really wanted is a method to "extract" a spline from the sketch, convert a spline got with "insert->sketch curve->Studio spline" to a 3D "insert->curve->Studio spline"
