IFC plot

in General

Hello!
I'm trying to find out whether there's a way to add to an ifc project made in Bonsai all the information that the Finnish government and the National Land Survey will require from all the projects submitted from 2026 onward. Has anyone yet modeled with Bonsai a plot with all its GEO properties (elevations , topographic elements etc)? If yes, I'd love to know what your workflow has been. Also, is there a way to import official maps into Bonsai/Blender?
Thank you so much as usual, you guys are all so very helpful! :)

    Hi, for which branch of construction you plan to create Ifc?

  • tessafktessafk

    Hi! The idea is to be able to submit the ifc plan of the building plus the plot with its elevations to the system to get the permit to build..

    Do you have an example you can share? This doesn't sound difficult. I use

    • blendergis to set up geolocation and import shp maps
    • cloudcompare to create meshes from las scans and import as obj
    • Sverchok to generate contours
    • Bonsai to turn it all to ifc elements

    This screams for youtube tutorial!

    This is a project made with the traditional Blender tecniques, but yes basically I would need to create the same plot but IFC, with the right coordinates, elevations etc.

    A tutorial would actually really be amazing!

    I haven't forgotten or ignored you guys, I'm writing a guide here:

    Note you can also extract contour lines from CloudCompare from just the point cloud, although it will be in raster. But depending on your workflow it might do the trick as an underlay. Tools > Projection > Rasterize

    Also on the topic of contour lines, here's a wonderfully simple shader based approach https://blender.stackexchange.com/a/212767/86891

    @JanF, I'm having trouble opening the guide you created.

    Yeah the whole wiki is down right now.
