Chamfer problem

Colleagues, good afternoon!
The question may be funny - but, nevertheless ...
I still can’t figure out how to make a chamfer so that it hits the touching edge exactly.
There is always some distance left. Maybe there is a way that I do not know about - so that when creating a chamfer, it automatically reaches the right place (which could be specified) and the bevel value is adjusted automatically?

Hi krass, it would be helpful if you could post the .3dm model file with the objects in it that you are showing instead of only a screenshot.

But it is normal in CAD chamfers and fillets that chamfers or fillets between surfaces at different angles to each other will be different widths.

Some explanation here:

You might need to use some method other than chamfer to get what you want if you are leaving some edges unprocessed. If you chamfer all the edges including vertical ones then you'll get juncture patches where pieces meet up instead of chamfer/fillet surfaces directly running into each other.

It's hard for me to know for sure what to suggest without being able to load the file and examine your particular case though.

Michael, hi! Thanks for the answer.
Perhaps I wrote a little confusingly and was misunderstood.
It's about this - I want that when creating a chamfer, it exactly docks with another plane.
Now this cannot be achieved - it takes a very long time to manually select the values - and still there is a distance.

How to avoid this "step" when creating a chamfer?

Hi krass it would probably be better to use a polygon modeling program to construct a faceted shape like this
because they are very focused on manipulating and matching things to make an "all quads" type structure. MoI
does not have that same kind of focus for working with faceted data.

For your particular case here though you can get what you are asking about by initially drawing in a line from
mid point to midpoint like this:







The length of this line is the chamfer distance that you need. When you run Chamfer snap
on to the ends of that line to get a chamfer like this:





That works because the distance you give to the chamfer command is then used to make offset surfaces and
the line that was drawn in was along a surface normal so it measured the needed offset distance.
