Cant create fillet on Manifold

[bobschulz1]

Hi, I cant create a fillet on this area. If I try in small sections the fillet doesn't seem to act correctly

If you want sympathy, I can give that easily.  If you want help or a solution, you'll need to attach your file, and let us know what version of Inventor you're working with.

Hi! I believe you are using Fusion 360, not Inventor. Let me move the thread to Fusion forum.

Many thanks!

1. Your fit point splines have too many spline points to have smooth curvature

2. Your sketches are under constrained and likely lack one, or more tangency constraints.

3. the fillet tool by default selects an entire tangent chain of edges. The points above might explain why that is not the case in your model.

4. You need to select all edges in a chain manually, if the tangent chain does not take care of that.

Thanks for your reply and I want to admit I am a self tough hack with autodesk. When I created the cutout I tried to make it as smooth as possible. Is this the curve that you think fusion is struggling with?

It might, but to sat for sure I'd need to have access to the design.

Please export your design as a .f3d file and attach it to the next post.

I appreciate your help.

I would start by fixing sketch 2.

here's the curvature comb on that curve-

got zoom WAY out to see all of it-

you have to many fit points on that curve.  you can probably do it with 5 or so.

Also, there is something wrong with the spline. After I deleted this point, the line disappeared. Odd, a point remains anyway.

At least the edge can be rounded now up to 0.07 in.

Thanks for your help. I never heard of a curvature comb. Do you have a recommendation to learn the tool better?
