Problem with several orientations and azimuth - shading 3D view

[JaviBrave]

Hello everyone.

I'm learning how to use Pvsyst v6.70 and I have a trouble related to shadings field with 2 orientations.

I have tried many options to solve this but It makes no sense for me. Please need help.

I add the 3D shading views:

https://ibb.co/6rd4sJ9

 

Also the compatibility system-shadings given by Pvsyst:

https://ibb.co/9b88mTj

 

 

It sames easy to see both orientations of the PV modules (azimut 0º and 45º). Both have 45º tilt.

How it is possible this happens? It's an easy correlation between azimut 0º and 45º. In the 3D images it makes totally clear. Where did the 10.8º come from?

 

I add the System Overview to make myself more clear:

You have defined an orientation #2 with Tilt = 45° and azimut = 45° but no PV 
array has been attributed to it.

Please double click on fields #2 to #9. In your system summary you can see that no orientation was defined for them: they have orientation #-1 instead of #1 or #2. So please open the objects and select the relevant orientation.

[JaviBrave]

I just don't understand. It has to be a bug.

I see what you tell me about the orientation #-1 in the system summary.

However, in each field between #2 and #7 it is 0º orientation which matchs with the orientation #1 defined in its menu. Also, for fields #8 and #9 it is written 45º orientation, just as orientation #2 in "Orientation" menu. Those orientations can be clearly seen in the shading views.

 

If I delete the fields #8 and #9 and also delete orientation #2 (45º). There is no problem with fields #2 to #7... The problem appears if I try to set different orientations.

 

Sorry if I have newbie doubts but I cannot keep trying without solving this.

 

Thank you.

There may be a bug indeed. You can send us your project (export it via the main window > File > Export projects) for review.
You can also try the following: within the 3D scene there is Tools > Orientation management, which can allow you to assign tables to a specific orientation.

[JaviBrave]

I have seen this menu Tools/Orientation management but it has no sense for me either...

I upload the project to wetransfer. If you prefer other type to send it to you I can change it.

Thanks in advance.

@JaviBrave Here is a quick gif of the procedure, hope that helps !
