Hey everyone! First post here and was having an issue following along with a tutorial that uses Fusion. Everything was going smoothly until I had to perform a fillet with extra point set and linear blend. It keeps showing a weird result where I added the point set as you can see in the image. When I do the same function on a extruded rectangle with no chamfer it works fine. Not sure what's going on or if maybe I'm struggling with something super basic. I included a shot from Fusion tut.

Hi Dan, can you please post the .3dm model file with the object before you're trying to place the fillet?

Here you go. First one is not boolean union.

Hi Dan, thanks for posting the file.

Is this the edge you're trying to fillet?


It's pretty subtle but I happened to notice these edges were looking a little darker than the others:


That's an indication that there are actually multiple edges being displayed on top of each other instead of just a single edge like you'd want to have. I zoomed in to the corner area and the problem is that there are few really skinny surface fragments in that area:


So there are actually several little tiny edges and surfaces in that back and corner area and that's what is going to interfere with getting a fillet running through there.

Maybe some of the pieces were just barely not aligned when doing a previous boolean step. It can be good to make things that you are going to boolean union to push a little ways through each other before doing the boolean instead of making things that just barely skim right over the same surface area.

Yep, that's the one. Thanks so much for the fast reply. So, I fixed boolean problem I had but I'm still getting sudden angle at New Point Set with linear blend. It seems to be and issue, for me, when trying to do it on a chamfered surface.

It looks like it starts out on the opposite corner as a small piece and then gets really skinny as it goes further up and around:

Yeah that looks like a bug in the variable radius fillet with linear blend. It seems to be ok without linear blend enabled.

It looks like maybe something to do with the fillet extension not being right. I'll take a look at it and see if I can figure out what's wrong. Fillet bugs can be very difficult to figure out though.

Appreciate your time and effort, Michael!

In the meantime I tried this workaround that seems to be okay. Instead of extruding a circle and then boolean merge my shape to it I just extruded the curve, applied regular fillet and then chamfered. Next step was a flow command and then another boolean merge to fix the minor distortion. The bend gives the fillet a little wonky-ness but at least I can move forward.
