Seems to me that as the edges are completed, the spaces are filled in. It is common working directly on CAD import to have to add “diagonals” and then the faces remain after erasing these. These are small inaccuracies with SketchUp dealing with 2d imports. I drew in missing edges and I did some “diagonals” and erased them in this instance and it works. But your drawing is missing so many edges. Why is that? You need closed loops to form faces.
And is there any easy of making faces easily for large scale projects?
And I have tried installing make faced plugin…it gets installed but it does not work well
So can I get help regarding it as well?
No, I don’t think so. Besides you need closed loops to get faces. When you have better closed areas Using ThomThoms plan tools may help. Work on a smaller parts at time.
These islands? They work OK for me in tracing over.
So there is not solution for making faces easily?
If there’s a problem with the inaccuracy of “flatness”
- You can take parallel projection standard “top” view. export a 3d dwg and import in SU again. Sometimes helps.
- You can use Sandbox “drape” command to drape the the plan onto a face. That makes a lot of the faces in this model.
But if you are just trying to get the few closed faces you have here, it shouldn’t take long. Most of them seem to work with tracing over. On the other hand the rest of the drawing is useless for making faces because there so few closed loops of edges.
Okay i ll try them out
Thanks for your help
I exported the edges to 2d CAD and re- imported and got all these faces (104) by drawing a rectangle in the plane of the edges (the ground plane it seems), select all edges and the face, then use contextual menu: “intersect faces/ with selection”. Makes me think the original dwg file import is very slightly not flat.
Still when I did this the curbs did not all separate out until traced over
These are typical problems in this process. Sometimes you get lucky with a very clean (and flat) import.
By the way Addfaces is pretty good but doesn’t work well on this model for me either.
I ll check out them in cad file
Don’t know if my one is any better than pbacot’s one, but you may as well have it. SketchUp had a duplicate component ID to fix, and an extension I use to repair the far away geometry fixed a lot of things. Then I use Eneroth Face Creator to do the face filling.

Nice one…Can i get to know what have you done for which the output has come out well
And thanks alot
And does eneroth face creator works for free??
Yes, and should work in SketchUp 2014:
Yes I’m working in sketchup 2014
What extension have you used for repair the drawing components which are far away
Here is the extension I used to fix the far away geometry. I’m not sure if it works in 2014:
It appears as SW Rescue My Model in the Extensions menu.
Okay thank you
FWIW I select all and explode any component and groups. I selected the visible elements then used the command Edit/ Invert Selection to pick the far away elements.
Before that I also purged unused, showed all layers and hidden geometry to see what was missing in the file.
ok thank you
