Filleting a Booleaned Hole

[braddewald]

I've always had this problem and decided I'd reach out and see if there was a simple solution. I've attached some images that illustrate the problem. Basically if you want to fillet an edge you have to be using an Editable Poly. But if you convert an object with a "hole" in it to an Editable Poly you end up with an edge across the top face as seen in "slide 3." Then when you fillet the hole's edges the verts around the intersection there get all jacked up. Is there an easy fix?

 

EDIT: By fillet I obviously mean a chamfer with multiple segments.

Personally, I avoid booleans, as much as possible, as MAX is vey bad in that area. It works vey dirty and bad, as you see.

The only clean solution is to stick with pure editpoly modeling, sad but true...max is a meshe modeler, not solid modeler, thats way so many bugs you'll find with booleans.

Its simple wrong way for max, better change the way you go, as you will make circles with no good solution.

Thanks for the quick reply. Yeah I kind of figured this would be the answer I got but I'm still holding out hope. Booleans are terrible in general but it's hard to beat the speed. Luckily most of the time these types of objects don't get too close to the camera so the sharp edges I get aren't the end of the world. Still, if anybody has a better option it'd be much appreciated.

You need to connect your inner cut verts to your outer edge verts. Then remove that diagonal edge to get a nice clean surface that chamfer will work correctly on.

 

For the images you posted, it'd be much better (and faster) to just inset the top and bottom faces and then bridge them to cut the hole.

this is more involved but it allows a cleaner fillet. (can be cleaned up further to have quads)

This could be made in less than a minute with edit poly modeling. Personally I would throw a turbosmooth on top and add a couple edge loops to control the hardness of the corners. Either way it would be super simple.

 

Another option would be to add the fillet you want on the boolean "cutter" object before doing the boolean. As others have said it is advisable to not use the booleans, Max is so easy and powerful to create these shapes already.

to Fillet the Booleaned Hole. If you did Boolean to a Box, then Select Booleaned Polygons in Editable Poly, then try Bridge tool or delete those, and go with Border Option. do Bridge from Border Option That's it. Thank you

Wow, that actually worked! Thanks!!
