PVsol Premium - How to connect two buildings in L-shape with pitched roof when drawing from AutoCAD base plan

[Gigmolike]

Hello,

I am working on a project in PVsol Premium where I need to model two buildings connected in an L-shape. I have a base plan imported from AutoCAD, and I manually draw the roof outlines on top of it using the drawing tool (pencil). However, PVsol always assigns a flat roof to my drawn shapes, regardless of how I draw them.

I tried selecting the outline first and then adding a polygon edge (as suggested in some guides) to help PVsol recognize it as a pitched/multi-slope roof, but it still results in a flat roof.

My main issues are:

1. How can I draw two separate buildings and connect them so they appear as one L-shaped structure with a continuous pitched roof?
2. How can I make PVsol recognize my hand-drawn roof outline as a pitched roof (gable or hip) instead of always defaulting to a flat roof?

I have attached images showing:

• The roof type I want to achieve (two buildings connected in L-shape with a continuous pitched/tiled roof and solar panels placed on it)
• What I currently get (two separate buildings with flat roofs that do not connect properly, with a visible wall gap at the junction)

I am importing the site plan from AutoCAD as a background reference and drawing the building footprints manually on top of it.

I have also included image links below to better illustrate the issue and the desired result:

1. This is what I got - current result in PVsol:
2. This is what I tried to draw manually - my attempt: 
3. This is what I need - the desired result (these two images show exactly what I am trying to achieve):
4. 

Any help or step-by-step guidance would be greatly appreciated.

Thank you!

Hello,

Thank you for your inquiry.

To create this L-shaped building, draw several polygons and extrude the buildings one after the other. You deactivate the collision (right-click on the roof) and move the buildings towards or into each other.

The polygons must be rectangular so that PV*SOL recognizes them as a gable or hipped roof:

This tutorial explains how to draw an L-shaped building. To watch the tutorial in English, you can select the "English" audio track in the YouTube settings.

I was able to get the correct roof on the second part of the sketch right away — the program recognized it properly. However, on the part we are discussing here, it still does not work. No matter what I try, I only get a flat roof.

I am attaching the whole project and some screenshots. If possible, could you please tell me where exactly I should mark it and how to set it correctly?

Thank you very much for the quick response, I really appreciate it.

Hello,

Thank you for your message.

Please delete the fifth point of the polygon. The rectangular polygon may only consist of four points.
