Hi
I read Vectorworks's guide
https://app-help.vectorworks.net/2020/eng/VW2020_Guide/SolarStudies/Inserting_a_heliodon_object.htm
I have misunderstand in this part:
"The heliodon graphic displays true North at the top of the heliodon. Normally, the drawing is oriented to page North (true North, not magnetic North), and true North matches the top of the page, with no compensation required for proper sun position. If the drawing was not created with this orientation, use the Object Info palette to specify a Rotation in degrees from page North. North set here should match true North in the drawing."
What "true North" in this case?
If I use magnetic in real world, What they call for this kind of North?
