Tricky Chamfers

jimmberry — Sat, 28 Aug 2021 03:53:21 GMT

I'm hoping to get some advice on how I can chamfer the zig-zag edge so that they form a point at the center like represented in the photo. I have a bunch of these to do so I'm hoping a pro can give some workflow advice on how to tackle it without a zillion planes.

I've attached a sample f3d file if anyone wants a closer look.

Thanks for any advice...

Like this?

Create midplane.
Split body with the plane.
Chamfer the top edges.
Discard the bottom body.
Mirror the top body.

If the pointy bits were all the same size and aligned with each other, then one simple sketch will do the trick:

If they aren't the same size or aligned then each point will need to be created individually with either a sweep:

or a loft:

Sweep version is in the attached file.

Zen garden rake?

If you are designing different versions of this shape I recommend using the power of Parameters and Patterns in Fusion.

I designed with 2 sides of the teeth arced, if you want a straight tooth edit Sketch1.

Elegant! My ends on the real model were a bit different but i just had to create an offset plane and do the drawing like you did. Then snip-snip!

Thanks this really helps me think about the workflow.

I only have about 6 months of fusion experience under my belt.
