Hi
I would like to generate a surface which is curved in two axis. Could you give me a hint how to solve this problem? See also the linked model with the defined profiles / paths: http://a360.co/2qQnKxg
Thanks, Kurt
Create curved surface
Accepted solution
With a few edits to the file, the Loft worked ok,
While not significant things, were the sketches derived from imported data?
In sketch 1, I found projected geometry, where there was no source, and no error,
I found two mirror constraints, and nothing mirrored..
Sketch 3, at the sharp end had some strange (to me) geometry too.
That said, to make the Loft work,
Edit sketch 1, draw a point at the widest part of the curve, and drew a construction line from the point.
With Sketch > Break, I broke the curve into two pieces.
Edit Sketch 2, added a vertical line from the mid Spline point, to the base.
Created a 3 point Plane for Sketch 3, from the two points in Sketch 2, and the new point in Sketch 1.
Fixed Sketch 3 on the new plane, deleted the old one.
Loft as a solid, will need more edits, but Loft as a surface has enough to succeed as it is.
Patch > Loft, Sketch 2 to point in sketch 1, used the 3 rails.
Sorry if the Sketch 3 reposition is not correct, you should be able to place it where you do need it if required.
File attached, Might help,
Hi davebYYPCU
If I go through your loft example, then I everything works fine. 🙂 But I'm not able to do it by myself. 😕
Could you please point me to the issue?
Thanks in advance,
Kurt
Gooday Kurt,
Quite a few issues, Sketch > Project > Intersect, will become your friend, for loft corners.
As I don't know your design intention, I have taken a few pics, and try to explain why Fusion will not loft for you.
The section marked with x, lower rail, is a duplicate rail, on top of itself, and causing selection problems.
The sharp corner in the top area, is not allowed as a rail, but can be used as it is, if you change to profile sketch1, then Sketch 2, with top of sketch 3 as rail.
You can't select the left half of Sketch1 as profile, because it is not shaded, need to correct that.
You can not loft anything except my preview at the moment because sketch 2 corners are not connected to Sketch 1 at both ends, need to be fixed.
When fixing Sketch 2, you can then get the kink in sketch1 to work by lofting A half of Sketch 1, to all of Sketch 2, with Sketch 3 as rail.
If you change Sketch 3 to go right across and break Sketch 1 at the top and bottom, you can get one piece Loft.
For now...
Will see if edits can get it done the way I think it can work....
Gooday Kurt,
Found more duplicate lines in sketch 1, fixed that by having one curve in all positions,
Cut the top and bottom curve at the centre line, then moved the Sketch two end points, to the intersection points.
Lofted with out sketch3 rail and looks like it will work as expected.
Might help....
