I have been having trouble drawing non perpendicular parallel lines to define a shape to push pull edit. When I close the lines, the shape does not highlight. When I zoom in to very large scale, I find that the lines do not meet, or that the 6± sided geometry is not in the same plane. Attached is Sketchup file that gives an example. To try to keep on one plane I drew vertical square with the snapping of the axis through other shape so I could define the intersection of edges by drawing a new line at that intersection. When I try to copy that line to create the parallel shape, I have trouble getting the copied line to be exactly the same plane.
My query is for tips on drawing on planes that are not aligned with blue, green, red axis.
Also, is there a way to program the snapping so you draw lines at different angles that are commonly used.
