 +And beyond this, if you want your kml __maps__ and 3d outputs to be generated correctly, you will also need to get the wall line orientations correct.  The yellow tick mark on the left of the line as you draw it must point towards the passage side of the line.  More on this on the [[drawingchecklist#wall|drawing checklist]] page.  You can adjust it with ''-reverse on|off''.
