I have version 16. My building is not square. The software seems to only allow walls to be built at right angles to each other. Does anyone know how to draw walls that are joined at other angles? Many thanks. Scotamoly.
I have v16 and just tried to create a trapezoid building. I found I had to turn off the 'ORTHO' switch. It is located on the right of the drawing options just below the lower toolbar. You can also find it from Tools->ProgramSettings->DrawingAids on the upper right quadrant.
