Another fillet question / example

Hello, all.
I have been following the current discussion on converging fillets. Here is another.




I managed to fill in the red area using a network - but I have no idea how to blend in another fillet along the yellow line. It does not have to be a large fillet; but it should not be square either.
Suggestions anyone?
Ron

Here is a 3DM. Not original starting point, but close.

Hi Ron, MoI can make a fillet in a situation like that, see the attached 3DM file:






But it will help the filleter a lot if your base model you create has a cleaner structure in it - on your model the side walls are fragmented into many strips and seem to taper inwards by some tiny amount, that kind of stuff is not good for filleting...

Yep, looks like MOI can fillet everything around it.

Then the way you'd get the additional fillet you're showing with the yellow line would be to select this entire chain of edges like this:



Then the filleter will be able to put in a corner juncture at the ending point:




But again this requires a cleaner model structure in order to work, there isn't much chance that the filleter is going to be able to do anything on the sort of squiggly network surface that you've got in the corner area right now. Probably the best bet for putting in something on your current model without rebuilding it to a cleaner structure would be to slice away some space and then use Construct > Blend to put in some smooth pieces, filleting is not going to be likely to work on spots bounded by squiggly little pieces.

EDIT: Didn't see Andrei's post saying the same thing...

Hi, Michael.
Thank you. It didn't start that way. Most of those mods came after the main fillets were complete. I made some divisions in some surfaces to make the network filler; and I also broke up the tapered sides to add a perpendicular section and blended the two surfaces. It's a mess - but it worked for a quick rendering. :-)

Thank you, Andrei !
I appreciate the advice from both of you. I will start fresh, and try to get a clean result in case they need mold drawings later.

Hi Ron,

Yeah unfortunately though filleting is much less tolerant of such things than rendering is...

Here is the "final" result of rebuilding. Not quite as clean as Michael's example, but it is a true solid with no known errors.
The sides are at 3.5 degrees draft angle; except for the rear 8mm, which are perp to the front faces.

Ron, very simple, is not it? :)
I notice at last time that a lot of peoply try to make simple things in very complex way and model become messy and it is very hard to work with.

I think the basic approach have to be:
1. Make base shape.
2. Trim it and modify.


You have to look on things from big to small, from silhouette to details etc... FROM BIG TO SMALL!
If you have to model some object, make first it without any details just base shape and then begin to make details. And when you start to make details also make it this way from base shape to detail e.t.c.. I see people some times moving from details to big forms and trouble begins. It is wrong way if you model from reference, you see all model and have to plane how to move from big to small.

I can allow to move from small to big if you make concept art and really did not know where you will be after 5 minutes :) But after that sometimes you have to go back and reapair/rebuild you geometry.


And the general rule is: ALWAYS TRY TO FINDE THE SIMPLEST WAY TO MAKE THINGS.
