Generate SLA lines
The tool is used to check the placement of frames on 3D terrain. It is an indicator on what PVcase based the frame generation upon. If the generation calculation is correct - the pink lines should reach another frame row at some point.
After pressing Generate SLA lines button select if you want to draw up indicative placement lines for the entire PV area or for selected frames. Then you can easily use the tool to remove generated SLA lines.
🛈 Important thing to note: This tool does not represent the shading from the frames - rather it represents the so called 'shading limit lines'. These lines show the parts where the shading limit would intercept the next frame above it at the height of that frame.
