I have been using the pencil tool to draw squares on the side of my building in SketchUp and then add photovoltaics to those squares using the OpenStudio Plug-In. All the sudden, whenever I draw lines, they are more bold than the other lines I've been drawing and it wont let me select the scare to add photovoltaics to it. It almost seems as if the lines are behind the surface when you select the them. I'm not sure what made it so the lines started to be bold, or how to switch it back.
