I’ve drawn the shape that you can see in the attached screencap. As far as i can tell, al the edges are co-planar in the red-green axes plane, and i was scrupulous in joining each edge endpoint-to-endpoint. But Sketchup won’t give me a face.
At the same time, you can see that I got a face with no trouble at all with the simple rectangle that I drew alongside as a test.
Hi , I suspect it not coplanar, Its good when doing what your doing to draw big rectangle and draw on that . It give the inference engine something to reference to.
If you look down and draw a big rectangle round it , it will show up the lack of flatness in your example …

So I just randomly started adding lines within your shape to fill the faces to narrow down the search to find where things weren’t working. I found these two stray lines, after deleting them and retracing other existing lines, the faces appeared.
I want to add if you’re finding a really particularly difficult point on the shapes try enabling endpoints and extensions. Both act as visual cues. Its helping with a plan I’m working on right now.
Simple version:
Sketchup gets confused by a big model with lots of copies of components. Reduce it. E.g. to draw a house of 1000 bricks, you only need draw the wall shapes, not copy & paste the 1000 bricks. You will then find faces draw easily & Sketchup runs faster.
