Surface fillets on vertices

christian_petty

The fillet tool should be able to add rounds on a surface. Unless I am missing a feature, you have to split using a sketch fillet then delete the face.

@radianrad It should but an example would help. I will pull a ticket and reach out.

@radianrad
Do you mean filleting a vertex vs. an edge?

christian_petty

@lana yes vertices

I finally found the Creo feature I was trying to mimic: About the Vertex Round Feature (ptc.com)

NeilCooke

The vertex round feature never worked very well if the surface had too much curvature. If you want to mimic this now, you can thicken the surface, fillet the edges, then remove the thickened faces. A custom feature would be the way to go if you do this all the time.

@NeilCooke this is what @lougallo demonstrated for me and it looks solid. I’ll use this in the future.

Having to thicken, fillet and then turn to a surface isn't efficient. Would be a great feature to add.

@NeilCooke how would you approach a custom feature for this? I'm new to FS, but this seems like a good opportunity to learn.

Just code it like you model it - opThicken, opFillet, opDeleteFace - there’s more to it of course but that’s essentially it.

I put a link in the previous comment to what I have so far. I am wondering specifically how you would tackle finding the edges on the body that correspond to the points selected on the surface. qNonCapEntity seems useful, but is there a more direct lineage from sketch vertex to body edge?

NeilCooke

There are a number of ways that this can be done by looping through each selected vertex, but the most efficient way is to use a tracking query. This will find geometry that was created from other geometry, in this case the edges created from the thickened vertices.

Thank you, looks like that works well. Glad to see I wasn't too far off, but I'll look more into tracking queries.
