I created a fillet for an inside corner, but the resulting curve is empty. Take a look at the attached pic. Seems like this should be a simple fix. Thanks!

is that a surface inside there?

if it is, can you upload the model in the state prior to filleting?

if not, in this scenario, you might have to run `MergeAllFaces`

prior to filleting.

Yes, they are surfaces. I’ve uploaded my model as requested. I performed a `MergeAllFaces`

prior to attempting the fillet again. Thanks.

Hi David – FilletSrf works on two surfaces, period - it does not care about maintaining a slid - it is a surface operation. What I guess you are after here is for all the purple things to be a single polysurface and then a FilletEdge on that vertical edge there. If all the planar faces are merged in the polysurface, as Jeff pointed out, it should work there. But there’s a bit of work to get all the bits into one polysurface first.

Yes, the one on the right is the desired outcome. So, what’s the trick in achieving that?

Nevermind. I unioned the solids together after dealing with some naked edges. Then I performed a FilletEdge and was able to achieve the desired results. As for the naked edges, I would up deleting the solid and dragging a copy into place. At some point I figure out naked edges; just not today. Thanks!
