Question about efficiency in modeling
-
Ah yes, many other modeling systems are based on triangular faces. I hadn't realized you need to export the SketchUp model to one of them. However, to prevent your bottom face from being over-triangulated you will need to isolate it from the rest using Groups or Components. Otherwise where the walls touch the floor will break up the floor even if you draw the line across the gap, and the export will therefore cover it with a bunch of smaller triangles.
-
SO I need to seperate every face which sticks to other faces by for example groups and do such lines/faces like shown in the OP to simplify faces?
Well sounds like alot of extra work. Do you happen to know if there is a plugin for that? Atleast for the seperating task?
-
If problem is triangulation surface you can use Triangulate faces by Tig
-
It's not that hard to organize your drawing with groups. For a rectangular floor you just draw a rectangle (Or rectangular prism for depth) and group (with a hot key). Go along and build your walls above. Group them so they don't interact with other touching geometry (Like the roof). Grouping (or using components) makes modeling easier.
Whether the program you are going to recognizes the groups is another question--or does it just add all the intersections anyway. if it does not keep the groups independent, then only draw visible faces.

I currently work on my models with the help of your feedback.
Now I noticed something like this:
If I connect the planes on the left and right, some kind of clipping happens and looks quite ugly. Is this likely to happen in other engines, too? I dont know which engine I will use so I cannot test it...
-
Sorry, I can't understand from your post quite what is the problem. Is the image intended to show the "some kind of clipping"? If so, I don't see it. If not, maybe you could post an image that does show it? The arrow on your image points to an edge. Without seeing the model, I can't tell you why this edge is visible or what will happen if you erase it - quite possibly there is a small misalignment.
-
Yea I am talking about this hidden plane. To fight "overtriangulation" in the engine I thought connecting the light planes on the left + right to a single plane.
I will stop doing stuff like this and continue on my model. Once I finish it I will upload it here and you might give me tips on problems you notice, okay?
But this will not happen soon as the model is far from being finished.
-
Good. Glad you are making progress.
There is probably an internal wall under that top surface and perpendicular to it. Why not continue with your project (WIP) and post the model, and ask how to do things? In this case what do you want to do? Get rid of that light-colored line? I think there's an internal face you need to delete.
If you don't know what renderer you will use, it's hard to say what the result will be, but most likely it will look quite different than in SketchUp. Fretting about the appearance in SU might be a waste of time, before you see the results in the renderer. Divisions in coplanar faces are generally not visible in a renderer, if the material is the same.

Now I noticed something like this:
If the surfaces are really "coplanar" & "pasted" & same color / Material and the "edges" not enabled (if it can) in the render engine
all will be rendered as a same surface!
(Remark the differences between images 2 - 3 with or without edges! 3 seems more light! )
It's the case in the fabulous free real time Visualizer!

Erase the edge and that hidden plane should go away.
