Dave,
I am really stuck on creating the 2D floor plan for my home remodel project. I am totally confused by the the addition of grouping and how to add additional lines (walls) into the second group called internal Walls.
I end up with lines drawn on what appear to be layer 0 but not within the proper group.
I am about ready give up.
This cant be this hard

The units precision setting in Model Info (properly labelled “Display precision” in SU 2019) controls only how values are displayed on the UI. It has no effect at all on how values are captured internally for the model.
Enable length snapping, on the other hand, affects how a value is captured regardless of the display precision. The gotcha regarding length snapping is that it means what it says: you can start a line on an imprecise point and then have the length snap to an exact value, leaving both ends of the line on imprecise points! For that reason alone I never enable length snapping.
I’ll PM you. Maybe if we look at it together it’ll help.
The three edges that I circled are outside the " Interior Walls - Master Bathroom" group, but use the Interior Walls layer instead of layer0. There are also a lot of reversed faces. No doubt @DaveR will straighten out how you got them that way.
I agree it isn’t right, problem is I don’t know why it’s not right nor how to correct it.
I see a lot of things visually on the screen that I’m sure indicate what is wrong. I just don’t have the skill or knowledge to recognize what is being communicated.
Rick
The error you have made is you have assigned the edges to a layer rather than put them in a group that is assigned to a layer.
See here how I cut them and paste in place within the group when open for editing.
I should have also set the edges to layer 0 as well.
All raw geometry should remain on layer 0 and only groups or components assigned a layer for visibility purposes. Only groups and components separate geometry.
By the way, please don’t bury your questions in somewhat random threads. Create your own thread with a relevant thread title so that people will actually see it and respond. I only looked in this thread because I was curious why it had resurrected.
Its not!
There are a lot of odd things about the model, including faces that don’t have edges, and edges that don’t quite reach the nearby edge. Here’s a modified one, see if it behaves more predictably.
For the interior isolated walls I had to make those be a group before they would push pull in the expected way, then I exploded the group.
Thank you Box I appreciate the response and the suggestion on creating new topic thread.
Hi Colin,
Yes I agree there are a lot of odd things in my model. I see the irregularities but I don’t know how I created them. Everything was going fine until I finished creating the exterior walls and made them a group.
I also created layers for internal and exterior walls. I assigned the groups to their perspective layers.
It was when I started working on the interior walls that I began to run into problems.
I was able to draw one room worth of interior walls.
I grouped them as interior walls. When I grouped the one room of interior walls it seemed to block out the rest of the external wall edges which caused confusion as to how I was going to add interior walls to interior areas well outside the interior group area bounding box.
When I would try to add a line in edit group mode the group bounding box would close and lines would end up being drawn on some other space, be it off layer 0, in a different group, outside the proper group or on base layer 0.
The model was acting as though open group and edit group were not remaining open.
It was obviously not right.
Perhaps creating layers right away was the wrong methodology. Grouping for some odd reason is a concept I am struggling with. I seem to click along with fewer issues when using components.
Dave R has offered to get on line with me to try and help determine what it is that I am doing incorrectly.
Rick
Dave R is a great resource. Get a heads up with the Sketchup Fundamentals These are interactive tutorials from SU. They are really great with the basics. Well worth the time.
Thank you RLGL
I have been through them and will definitely revisit.
I am another end of rope user by the described problems and It only frustrates me more when I see these “operator problem” replies because I think this issue is not about just making sure the drawing is locked on axis but about what the application does without warning: approximating on snaps and breaking your planes with hidden lines! This should just not happen, and it is a program issue! It’s not “normal” operation when you try to close a face with a axis locked line and it snaps on the slightly crooked lines every time till you have to erase all existing lines on it’s path and redraw the orthogonality. THIS is what needs to be recognized and corrected, because NORMAL would be that a line goes where YOU want, not where SU wants. Hope the next versions will do off with this “feature” that forces faces to close even though not all its geometry coplanar.
I am confused about what you are seeing. A face by definition must have all coplanar edges, a face will not form unless that is the case. I understand learning new software can be frustrating, I was frustrated often when learning SketchUp many years ago. Now I use it daily, and like many other users it is an important component of my work process. The program works very well, and although you might not like to hear it most problems including those of the original poster are caused by operator error. The inference engine that controls the “snapping” you see is a core aspect of SketchUp for about 20 years, it’s not going away and no serious user of the software wants it to.
This forum is a fabulous resource in learning SketchUp. If you post a model that you are having trouble with here, or ask a specific question about how the software works, I guarantee you will get expert friendly relevant help with SketchUp. Do yourself a favor and let us help you, post a file that exhibits the behavior you are talking about here on the the forum.
Unfortunately this part isn’t true. The tolerance for coplanar faces isn’t as small as it is for coplanar edges. It is possible to have an apparently flat on the ground almost surrounding edge, draw the last leg, it fills in with one face. You can select the face, and know for sure it’s coplanar. But then draw a diagonal line, and now you have multiple faces on top of each other, because the edges were not exactly coplanar.
The recommendation is to turn length snapping OFF. In model units set display precision to the smallest unit on the list.
This is a great piece of software, but for some the learning curve is very steep.
I know about “flat” faces not being entirely flat, (one or several vertices out of plane), but I especially liked the bit about “upload your model so we can see what you are doing”.
I’ve occasionally come across this in a busy model. The plane can be sort of coplanar… you can close it by drawing many edges across, delete the edges and the face stays but it will never be secure from going non planar (if you leave it like that). But this isn’t common. Also there is the frustration when you are drawing just off axis–this is true. But there are only three axis so this isn’t common either. This is something that has caused people to ask for a temporary override of axis inference. Until then it takes some tricks to work around this situation.
Yes it’s confusing I guess, if you only work with clean modelling from scratch you might not encounter what we are talking about here (and you can see there are a lot of us, experienced users), but when you work on imported geometry these kind of issues seem to be unavoidable, and this is not a model specific misbehavior. I don’t have time to convince anyone here unless it’s one of the software developers in which I’m sure they know what we are talking about. It’s just a ■■■■ shame for such a good modeling tool to be so unsuitable for 3d printing. If it was just about modelling/ rendering, most of us went with it, but it’s time to let manifolds in the SU enviroment.
Thank you
I can remember almost abandoning the program after hours of frustration because my walls were all a mess. 2 things that help are
1 in styles change display to color by axis and look for black or off axis lines.
2 The plugin vector tools can force vertices to be co planer. I think there are Utube videos on both.
You can get there I am producing high fidelity Models of 5000 s.f. Houses now.
