Use case : Helios3D

PVsyst automatically groups the fields from their nominal orientation, which means that :

• fields with the same tilt and azimuth (with a tolerance of 0.1°) but with a different slope (because they follow the ground slope) will be grouped together
• domes will define two orientations, one for the front panels and one for the back panels
• the orientation tilt, azimuth and baseslope values are the average of all the fields linked in it

There is no maximum number of orientations in PVsyst 8 onwards which means that all fields of your H2P file will be grouped in orientations.

And the new orientation management tool allows you to group fields manually if you don't like the automatic grouping.

Reopening old variants

If you worked on Helios3D projects with older versions, you will be able to open them again in the newer ones and their orientations definitions won't change which means that you should get the exact same variant.

But if you import the H2P file once again in the shading scene, orientations might be different because of the algorithm that is now used.
