Problem I can't really describe in subject line

Hmmm, it does seem like there is an issue with a simple surface intersect.
This is flat and average size and it still forms strange cuts and overlapping faces.I can reproduce your example ...

This is flat and average size and it still forms strange cuts and overlapping faces.I tried reproducing your model and it did all the weird things yours did except it kept deleting the center diamond face. The big difference between this and the problems I have had is that this one (at least for me) is easily correctable by drawing over some of the lines. Was that your experience?
How did you come upon this, just tried different things until you hit upon this one? What (if anything) does it tell you about what is happening, and why?

what it tells me is it's a bug, where 'on face' isn't the same as 'on plane'...
none off them should need to be 'moved' onto the face, that's where I drew them...
this is even more of a pain on 'curved' faces because "how do you align back to the face?"

No, coincidentally while reading your question I was working on a mechanism that needed that shape, or at least I was working out the layout that way and stumbled across this particularly stubborn group of edges.

Like Driven It tells me it is a bug, but a bug that has been around for a long time and sort of gets swept under the carpet. Generally you can work around it by reintersecting or welding etc, but as I see it, a line on a face should cut the face and if they don't then it's a bug.

Best guess about the whatever.???
I'm not sure that this is even what you are all talking about but
There is a [break edges] fcn that shows up in the [Edit Menu] and it does not show in the [Plugin Mgr] and defaults to [Break Edges] checked.
It exists in the View/Toolbar dialog but there is no way to get rid of the default except by invoking the on/off from the icon.
It will default back to cut line mode on when SU is re-opened again.
Maybe this is at least part of the fun.
SU 2015 PRO latest version.
Drives me crazy as no way to remember whether a line will cut a line or not on SU open.Y'all figure

dtr, I think you'll find that's a plugin not a default option.
From memory Julia Eneroth has something like that. -
Hi Box
Right it is a plugin but might be part of the problem if it is loaded.
Thx

Group the geometry and explode it.
It might them merge correctly.
It's to do with twisted-looped [à la bow-tie] forming faces' perimeters... -
Go to styles, edit, and add a checkmark to Display Endpoints.
If you have BreakLines=on the endpoints will appear at all crossed lines. If it is off then only at the end of each line.
WRT two faces that seem to be one (connected at one pont)... I've seen the same thing on numerous occasions. What I did was draw two more lines rather close to the point where the two faces touch thereby creating two small triangles. Delete one of those faces, erase the line for the other, finish by adding a line to close the face you just opened. Everything should be an individual face now.

Yes this has been around since the @last days. I only come across it when I've inserted a siteplan or similar from AutoCad. It used to be reported as a bug a lot, but I guess it's been grandfathered in as something that can't be fixed? Or maybe it just keeps being put on the "next time" list.
