Problem I can't really describe in subject line

Most of the times an intersection of the face and the lines will separate them again. (Make sure that the scale of the model isn't too small)
Yes, I know that sometimes that will work, but I'm talking about the times when nothing works. When you intersect shapes frequently the face intersected cannot be selected but most of the time just drawing along one of the lines fixes that. But there was no intersecting in the situation I'm talking about. Nothing but drawing lines and curves on a planar face, and up to a point you can select faces just fine, but then suddenly none of the faces can be selected. And this last time it was working just fine, I had already erased the faces I needed to erase, but when I saved it all of the erased faces came back and could not be selected no matter what I tried (both on the model still open and the saved model).
And yes, I always make my models extra large to maximize their workability.

When this sort of problem happens to me I use "generate faces" from context menu (I have a shortcut for it), selecting all lines and that makes every face deleteable again. The thing is you have to do that and you shouldn't. I can't believe the pissed I'd to have to redo that to my faces everytime I'd load a model.
Must be a plugin (or extension, whatever) I can't find it anywhere within SU 2015. Are you referring to one of these two plugins (although they don't say "generate" faces, only "create" or "make" faces.

I've used TIGs Add Faces plugin for this.

"Generate faces" is an item added in the context menu by Fredo's "Tools on surface" plugin.

Maybe I'm missing something, but I can't seem to find "Generate Faces" anywhere in Fredo's "Tools On Surface" menu

Sorry I was meaning to say that but forgot. Thanks Massimo

It's not on the tool menu. You have to select some edges on the model and right click on it.

Oh. Unless there's still more information that I need to use this feature correctly, but don't have, this will not be of use to me. If I have to click on each edge, I'll just use weld, but the last model that had this problem had a huge number of edges that would need to be selected. Simpler to just start over.
Thanks for the suggestions. Just another SU quirk to add to my ever-growing list

I can reproduce what you are getting but scaling a square by 100, moving one corner up on the blue by 1mm then scaling down again. This means the face is not coplaner by only 100th of a mm so SU puts the face back but it is out by enough for the edges not to intersect the face correctly.
So my guess is it is tiny inaccuracies in your model, you do such precise work and nudge vertices around a lot, so perhaps in this case you are working at too large a scale. -
Do you have the automatically fix my model box checked. I'm guessing you might.
It could be that there are small errors in your model and the autofix is causing this behavior

So my guess is it is tiny inaccuracies in your model, you do such precise work and nudge vertices around a lot, so perhaps in this case you are working at too large a scale.I think I understand what you are saying, but not sure it would apply to my modeling techniques. Yes, I do use a large scale with my models, but I don't scale them back down again as you seem to be suggesting. They are large to begin with and they stay that way. And sure I know that if I move a corner up by even the tiniest bit it will no longer be coplaner, but, again, that is not something I would do.
In the case of this last instance, everything was fine, I had deleted all the areas I wanted to, no problems. But as soon as I clicked on Save the deleted areas became undeleted and unselectable. On both the open model and the one I had saved. There was no going back, it was done and nothing could undo it.
I think when this happens again I had better just walk away from it for a while, a long while, and when I've run out of new cusswords and my blood pressure has dropped to a reasonable level I'll come back and work on another model for a while. And hopefully that one will progress the way it should, without something weird and inexplicable happening to it.
Yeah, I know Sketchup is free and all that, and problems are going to occur with any program. I just want them to be problems that I can solve. Not have to grit my teeth and somehow live with.
Things were so much simpler before technology took over the world.
I have thought long and hard about the possibility of just getting rid of my computers, making a clean break of it. And I could live with that, except for one thing - information. I am so used to finding any sort of information I want almost instantly, I just don't think I could go back to actually using a library and phone books and all those archaic stone-age sources of information I used before the dang internet.
Oh well. I'm gonna take a nap.
I long for the 60's, they were fun.

Is there any possibility there is hidden geometry floating about that is creating havoc.

No, I'm certain that was not the case.
The next time it happens I will post the model here. Until then life goes on.
I truly appreciate your efforts

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.

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.
@hellnbak said:

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.
