Tricky!

Good solution OSTexo,

I come across this problem occasionally too and there is no easy way to solve it with conventional tools.

Your post is very clear and easy to understand.

VERY COOL, OSTexo !!!


I took the easy way out .... lol

Not what I exactly wanted but I can live with it.

I like your solution better.

Hello,

Glad I could assist. I'll have to keep this technique in mind in case I run into a similar issue with filleting.

I down loaded a trial version of ViaCad and stumbled my way through to get something close to what I have in MoI. It gave the same result as MoI
but it did allow me to radius the outside edge (0.5 R) where as in MoI, it tried, but it didn't finish the deal ...

Hello jetblast,

You could keep that fillet that MoI generates and use it to Trim away and delete the undesired part of the solid. Then try to Join that fillet to the rest of the surface to see if it's watertight.

Hi jetblast,

> where as in MoI, it tried, but it didn't finish the deal ...

It looks like MoI's filleter got confused in the part of the process where it cuts away space in the main object.

When it runs into an error like that, it still returns the fillet surfaces that it was able to generate so you can use them, like OSTexo mentions above you can probably use the Trim command to cut the main object and then join the fillet into place in that case.

The geometry library that ViaCAD users does tend to handle a lot more fillet corner juncture type cases than MoI's though so it's not a bad idea to use it to assist with filleting like that.
