When unwrapping a cone, created with a "Fill Surface", it raises an error.
A cone, created with a "Fill Surface" needs to be unwrapped on a plane, but it raises an error.
The issue here is that a "Fill Surface" is not "Developable".
"Unwrap Curves" is used to unwrap curves and points from a conical, cylindrical or ruled "developable" face onto a plane.
To correct this :
- Use a Ruled face :
* Alignment Developable
* Start Filler Surface Type Generalized Cone (to match the lines connecting the arcs/circles)
* End Filler Surface Type Generalized Cone
- Unwrap Curves
* Select Curves
* Select Face
* Tangent Datum Plane
* Select Point
The same can also be done with a Cone.
