Hello:
I would like to show a little experimental script.
First my model in FreeCAD.
Second the model in DOE-2.2
I've not included the shades, materials, layers, schedules, ..., ..., ...

Re: BUILDING DESCRIPTION LANGUAGE
interesting... I never looked much at DOE2... Does your script build the "boxes" out of the walls?
gbXML seems to work a bit like that too, I had began to work on an export script but it didn't go very far yet.

gbXML
I was thinking to write a translator for EnergyPlus (really I was planning a workbench)
Both, EnergyPlus and gbXML are family ...
Re: BUILDING DESCRIPTION LANGUAGE
Sorry for highjacking ...
I have never worked with neither DOE2 nor gbXML. Just some question ...
- These languarges describe a building with volumes (spaces).
- You are generating the DOE2 from a modell off walls and slabs?
If both are true such macro could be adjusted to create building openstreetmap data because this is volume space driven too. Something what is in my mind for years, because I have a ifc of any real building we do at our office.

Re: BUILDING DESCRIPTION LANGUAGE
I was looking the openstreetmap project.
I used the arch spaces tool (with the two options 1.- from boundaries 2.- from a base solid object)
The arch spaces tool is designed for interior volume ( I think so ...?)
If you need the exterior envelope of a building, an arch structure (like a boudbox) extruded from a Dwire is sufficient.
This seems trivial
This other seems very difficult
I'm generating the model from the interior face of the walls, that they are coincident with the spaces definied.
I don't see the Osm3d manual, where explains the model description of the building (Exterior faces, I understand)
My macro includes a basic mechanism for calculating vertexes of faces polygons, azimuth, tilts, ...
Link the page with the Osm3d geometry model

Re: BUILDING DESCRIPTION LANGUAGE
Hi!
It's a bit off topic, but talking about energy analysis and 3D FOSS, I suggest Vi-Suite, a free software plug-in for Blender, an interface to EnergyPlus, Radiance for lighting simulation and other interesting features.
p.s. Thanks so much for your great work with FreeCAD and the FOSS comunity!

Re: BUILDING DESCRIPTION LANGUAGE
Interesting, so my question is: how deep this application is integrated into blender? how easy a blender plugin can be ported to freecad?Giulio wrote: I suggest Vi-Suite, a free software plug-in for Blender

Re: BUILDING DESCRIPTION LANGUAGE
Thanks for these links
I was not aware that there are already such many informations on lod2 free available.

Thank you for your idea. I didn't know it.microelly2 wrote: Interesting, so my question is: how deep this application is integrated into blender? how easy a blender plugin can be ported to freecad?
My problem with Blender script is that I don't know the blender API. It's a little different, but sometimes I've obtained useful solutions from there.
I've written an Energy+.idd reader. Now, I can create instances of "EpObject" in FreeCAD.
I've begun with BuildingSurface:Detailed and it works very well.
The problem is that there are 757 different objects. A wide variety of fauna.
do you have previous experience with e+ simulations?
Thank you for your interest and comments.
I see the synergy ...
