How can i loft from a non-planar 3d sketch curve to a single point. Basically this would be analagous to perspective projection lines from the 3d curve to a single point.
I tried this and it worked ok for me when using surfaces, trying to go straight to a solid failed with the error "cannot knit sheets together". It must have something to do with the the complexity of the 3d sketch.
Attach your file with the example profiles....
I have no file to attach since i am creating this. Basically, think of a triangle sketched on the surface of a ball. The triangle is a non-euclidean one made of three arcs. I want to make a cut in the ball following projection lines, each from a vertex of the spherical truangle to the center point of the ball. I know i can loft from a triangle on a plane to a point and make the cut that way. But for the spherical triangle that would mean first mapping the points to a flat plane before doing the cut. I was wondering if i could do this easier by directly doing a lofted-cut off the spherical triangle.
My actual cut is more complex than a triangle.
Hello Mark, ..you can do a surface/solid loft between a face and point.....in this case I have both a face and curves.. if you only have th curves, you can make a surface using Fill, Boundary, Loft.... mage/file attached.
Thanks for the tip! Maybe you could look at the file I created with a different approach. Two lofted-cuts were made with composite curves. Lofted-cut 1 worked as i wanted it but not so for Lofted-cut 2 which removed the opposite material instead of creating a pocket/hole. Un-suppress Lofted-cut 2 to see the problem. Why??
Hey Mark,.. what is happening is ZTG (zero thickness geometry) or sharing a singular point with both cuts.. and in this case it's flipping/inverting the cut at the center to the outer side (a valid result) because the center cut is not allowed and it faults( ZTG).
Sorry but suppressing the first lofted-cut does not change the behavior i get with the second lofted-cut??
