Ill redo the curve and repeat the process - then filleting should work.>>Do radius values of 0.5 , 0.6, 0.65, 0.75, work ok for you over there? Are any of those adequate?<<
Hi Tom, I loaded your last posted file and radius values between 0.55 to 0.9 seem to be working well with it now.
Will anything in that range do for what you're looking for or are you trying for a smaller value than that? I don't know at the moment why the smaller values aren't working, but I can investigate some more if you want.
After a quick look, it might be the same kind of problem on the other cutting direction, looks like slight creasing here:
Hi Tom, yeah it's pretty much the exact same thing on the profile on your cutting object:
If you tune up that curve so it's fully smooth with the lower line, and then make a new cutting block out of that, I'd think that should fully clean things up. A quick way to put in a smooth curve between 2 lines is to select the lines and then run Construct > Blend.
At some point I may modify the Edit > Join command to look for things that are nearly tangent and automatically adjust them to be fully smooth with one another but it's a bit of a delicate thing to do always because in some cases it can kind of change the shape too.
Hi Tom, I've attached a tuned up version here - I did an "untrim" on your main body to restore it to its original full shape, then deleted the slightly off round corner in the above screenshot and put in a curve blend in there instead and then extruded a new cutting block from that, then did the boolean.
With this attached version you should now have "all systems go" for doing any fillet radius along that spot.
That particular type of thing with things being only just a 5 degrees or so off from smooth tends to make filleting pretty cranky.
Thank you for the patience, your informations are really helpful. Impossible to come up with
a solution without it. Will have a look at the file - great !
Dealing with filleting I realized that it is not possible to round with a perfect circle - for example if
you have a distance of 2,00 it is not possible to fillet with radius 1,00 exactly but a bit smaller than
the radius needed for a perfect circle.
Hi Tom, the fillet will fail if it would cause a face to be entirely consumed away as would happen in that case. The fillet engine does not currently know how to handle that type of case.
