Hi,
Thanks for the advice. I should have mentioned that I have made everything into components already. It does help though, to put the components into layers.
The warning mentioned is "Constrained on 1 from point." It shows up as I am about to complete a line. What does it mean exactly?
I've reviewed my geometry and found little slivers of added thickness in the walls caused by not using the push/pull tool correctly (most likely). Once the extra lines were removed so the faces were on the same plane, the redrawn lines resulted in the faces appearing as expected. SketchUp is soo smart and I'm not.

Hi,
I've been using SU 8 for about a month now (on a mac). It is a useful, wonderful program but very frustrating too.
I'm trying to create a gable end (roof) in 2D so that I use the pull tool to extend it over the structure. The basic shape is easy but when I try to modify it (to add eaves and notches for the rafters) I see this warning. What does it mean???
The additions I make don't seem to be on the same plane as the basic shape because after adding the lines, no face appears. I've hid the underlying entities (Walls, etc) so they don't interfere with my connections but maybe they are anyway. Any tips.
Thanks
