Planes that do not close

To check your model for off axes lines, open the Styles window, select the Edit Tab, select the first cube (hover over it and it will say Edge Settings). Now go to the bottom of the window and find.COLOR. It should say ALL SAME. Click on the drop down and pick BY AXIS. Doing so will make all the lines in your model that are on Axis the proper axes color, those that are not will remain black. Fix the black ones by erasing and redraw them making sure they remain the proper color.

Just be aware that this facility in SketchUp works “to within tolerance”. That is, it will color not only lines that are perfectly aligned with axes, but also ones whose ends are on axis to within SketchUp’s cleanup tolerance. It is possible to get lines colored that are far enough askew to cause issues with things such as pushpull and forming faces.
