Digital model

[MEURVILLE]

Good morning,

I would like to import a digital model from the REVIT software onto PVSYST. The format of this mockup is IFC.

How can I import this model, because PVSYST only specifies the 3DS, DAE or PVC format?

Is there a particular procedure?

Thanking you,

[Stéphane Metz]

Hi Meurville,

The IFC format is not supported by PVsyst. As mentioned, only 3DS, DAE, H2P and PVC are supported.

The solution is to convert your IFC files into one of the supported formats (DAE or 3DS) with a dedicated tool such as Sketchup.

Thank's

Good morning, 

we have the same problem. Although we were able to create a usable DEA file with Sketchup, it unfortunately produces an error message that PV modules must be at least 2-3 cm apart. 

When importing, the objects representing modules are doubled, the planes are less than 2 cm apart. What do I have to change so that the objects are not duplicated or the layers are further apart?

best regards

Michael

Hello.

PVsyst reads the DAE file and import the content of it. You should check the scene in your source software, adjust it (add space between the tables if needed) and regenerate the DAE file to import it again in PVsyst.

If you cannot (or don't want to) add more space in your source software or modify the scene in PVsyst, you can modify the following advanced parameter in "Settings > Advanced parameters":

 

If you still encounter issues, you can deactivate those checks from the shadings scene in the menu "Tools" :

Please make sure to carrefully read the warning displayed when disabling the check as disbaling it can give incorrect shadings calculation.

Greetings everyone,

We are designing a bus parking garage in Revit 2024 and would like to specify PV panels on the roof. Using Lumion we generated DAE file and tried to import it into PVsyst, but couldn't do so due to the DAE file large size. Having said that, what's the largest DAE file size compatible with PVsyst?

The second question is about the best workflow for PV system design in PVsyst:

Should PV cells be placed on the roof in Revit, Lumion or PVsyst?

Dear Obulshteyn,

 

I suggest designing your PV panel in PVsyst. After that, you can press "Ctrl+G" to view the position of all your PV tables. Once you find the right position, you can extract this data and redraw it in the software of your choice.

ok, thank you, but first the DAE file needs to be imported into PVsyst, correct? If so, could you respond to my first question: "Using Lumion we generated DAE file and tried to import it into PVsyst, but couldn't do so due to the DAE file large size. Having said that, what's the largest DAE file size compatible with PVsyst?"

Who can resolve this issue?

Dear Obulshteyn,

 

There is no maximum size limitation for importing a DAE file or other files. The ability of your computer to open the 3D scene depends on its configuration (whether it is powerful or not) and the complexity of your drawing—does it have a lot of faces or objects? This could be a limiting factor.

To clarify, could you please send us your DAE file at support@pvsyst.com? This will help us identify why you're having issues importing and reading it. Also, I’m not familiar with Lumion; could you explain what it is?

The DAE file referenced above is 276 MB so it cannot be sent via email; is there another way to get you the file? Lumion is just a 3d rendering software: Industry-Leading 3D Rendering Software | Lumion - Lumion 3D Rendering Software

Dear Obulshteyn,

 

Maybe you can send a screenshot of the scene in Lumion. However, I suspect that your scene contains multiple objects, which PVsyst has difficulty opening.

The purpose of the 3D scene in PVsyst is to calculate shading on the PV surface. If your Lumion project includes elements that don't impact the PV surface, I suggest removing them.

You need to simplify the drawing as much as possible, as excessive details add complexity and could be one of the reasons it fails to open in PVsyst.
