Cannot sketch on lofted faces

Anonymous

Hi together,

 

I'm relatively new to Fusion 360, so maybe there is a better way to do it. I want to create a solid body between the two sketches.

I used Loft between both sketches. And then wanted to draw sketches on the surrounding faces, this is possible on one face, but not on any of the others. Using the Curvature Map feature, I cannot see any non-planar faces, so why can't I sketch on any other side faces?

that's just the way loft works.  There may be some subtle mis-alignment that causes the rest of the faces to be created as spline faces.

 

Because the faces are nearly planar, you can create a workplane through 3 points on the other faces, and sketch on that plane - it should be pretty close.

Lofts create NURBS surfaces. in Fusion 360 you cannot sketch on NURBS surfaces. You can only sketch on analytical geometry. E.G. faces that are created by extrudes.

Scratch that. Jeff is right! That loft should create procedural geometry if - and that's the if in this case - the sketches are accurate.

See the Attached file (I simplified things a bit removing dozens of duplicated dimensions).
