I have a deck floor that is flat. When I say it’s flat I mean it’s flat. I used inference locking religiously. It does form a solid face. There is no hidden geometry and when I scale it the only handles are the ones that show up when scaling a 2d surface… That being said, when I try to draw a squar…

As usual, there are two things to address here: defects in the model you have built, and possible problems with your workflow. We can say little about the former unless you share the model. And without watching over your shoulder as you work, we can’t with assurance say much about the latter. As …

Fair enough. I have no problem allowing that I messed something up… my question then becomes… why does the surface show as and, for the most part, behave as flat? Does sketchup just flatten things within a certain margin of error? Seems rather counterproductive if it does because any further work on…

Yes, SketchUp does make faces when the points are “near enough” to being in the same plane. If it didn’t do this it would be worse as the tiniest difference between two floating points numbers would make face creation fail almost every time. I don’t think it moves vertices though to make your surfa…

[image] 5pl1n73r: Does sketchup just flatten things within a certain margin of error? More the opposite: SketchUp decides the points are “close enough” and leaves them alone while creating the face. @McGordon is correct. The explanation is somewhat technical. Except when the points lie perf…

I’ve had the same problem even when drawing on any of the primary axial planes. Draw a face using the rectangle tool, even forcing the plane with an arrow key. Move it a bit on axis. Pushoull to make a wall. Try to draw a rectangle on it to make a window or door opening. Often fails to cut the …

Thank you all for your explanations and information. I looked back on some other similarly large and complicated models I have done and found that I had been able to keep them at absolute zero. I must have messed up somewhere on this model. Happen to remember the name of that extension? Sounds usef…

[image] 5pl1n73r: Happen to remember the name of that extension? Sounds useful Enoroth’s Flatten to Plane can do it: https://extensions.sketchup.com/en/content/eneroth-flatten-plane There are probably others.

I have absolutely the same problem, I came here in dusgust looking for answers. Now I just drew a rectangle on green and blue axis only, put a hole (circle) on it, expanded it to size on the green axis, and it doesn’t ‘cut’ for a better word. Click on the part and it highlights the whole lot and jus…

Share away if you can, will take a look tomorrow for you.

I did not expect such a fast answer, I am very sorry but I am about to travel for business and won’t be back til Monday, thanks for the fast reply. BTW, share what, the file, picture?? Mark
