Hello,
really missing possibility importing background from autocad, sketchup, google earth.

Possibility importing 3d objects from autocad/sketchup.

Drawing here is really tough thing.

Already asked by many users !

However it is not simple: unlike most 3D programs, the PVsyst shading 3D data are constructed with a very strict structure (the "native" data are elementary objects with their sizes and position/orientation, which are reconstructed and repositioned by the program at each execution). This structure is very difficult to reconstruct from other unstructured data in an automatic way.
Unless we ask the user to construct his objects in Autocad with very rigid rules, which withdraws 99% of the interest of the Autocad import facility ! (and checking the topology and the integrity of these data would be a titanesc work).
On the other hand, architect drawings usually include many details not relevant for the shading calculations. Then PVsyst cannot deal with too complex objects (the calculation time grows with the square of the number of elements), and will probably have to simplify the drawings.

However we will start soon to study the possibility of a link with Sketchup. If it is really feasible, this should not be available before several months (autumn ?).

Andre,

Apologies for double posting this one, however I think it is more useful that I post this to the forum rather than to your individual email account.

Rather than importing geometry directly into PVSyst (which as you've noted below, will be near impossible), the function to import a 2D .dxf underlay would be very useful if a drag and drop and snap functionality can be incorporated. This still allows all of the geometry to be built within PVSyst and to the PVSyst rules, but allows us to easily locate objects relative to one another, which at the moment is a cumbersome task.

This is a similar approach to what is taken with the majority of building energy simulation programs (i.e. IES Virtual Environment, DesignBuilder) which have very strict geometry requirements. This probably isn't easy to implement, but I think it is a sensible middle ground between no import capability and full 3D import capability.

Happy to elaborate further if necessary.

Thank you for the suggestion, it is really very interesting.
We will study such kind of possibilities, when the Import from Sketchup will be quite ready and released...

Bonjour,

moi aussi j'aimerai importer des batiments modélisé dans sketchup 3D /dwg/dxf puis implanter mes champs PV.

cela simplifierai bien le temps passé.

je sais qu'il existe Le format IFC (Industry Foundation Classes) qui est un format de fichier orienté objet utilisé par l'industrie du bâtiment pour échanger et partager des informations entre différents logiciels.

Avez vous une date prévisible (annoncée en automne) de la sortie de la version intégrant cette fonction ?

cordialement

Je reviens 5 mois après, as t on des nouvelles de l'évolution de la possibilité d'intégrer du 3d depuis dwg ou sketchup !
surtout avec l'apparition des lasermetres 3D

Hi there.
As you said "Already asked by many users ! " but still there is no progress in that direction.... do you have an update about this highly requested feature?

Another vote for the import ability!

As an intermediary option, you could make the specification for the Shadings Scene or Helios3D import files open source, as currently we're forced to look at rather expensive proprietary providers. You've mentioned before that at least some parts of the program are written in Delphi and I for one would be quite willing to try homebrewing some import code while you sort out the details. Obviously we would then take on the risk of inaccurate input. Indeed, this was something I considered for my dissertation several years ago!

James

PS - Off-topic but really pleased with today's update to the Module Layout page, thank you

Any updates regarding the possibility of importing 3D models from sketchup?
Last year I found a sketchup plugin in the pvsyst system folder and tried it with success but then I couldn't import the generated file in pvsyst and I was told you were working on that.
The plugin is still there in the new versions but there is no other progess in this field.
If sketchup is not going to happen, could we know what other software is more probable for such a capability?
Thanks in advance for your time.
Best regards.

Hi all,

anything new about this ?

there is a lot of free .lsp to extract points coordinates from dxf / dwg format to csv.

that would be a good start to have such a feature that can import 2D or 3D from csv. even we have to redesign the faces of the polygon.

well thx for your reply,
