BIM to 3dsmax: divide/split up a wall/floor/roof composition in parts?

Hey all,

I'm trying to think out a workflow from BricsCAD BIM to 3dsmax.

What I'm running into is that a wall with a composition (inner and outer material) is one solid object in 3dsmax. Thus, when assigning a material it is used for both the inside as well as the outside. Is there somehow a possibility in BricsCAD BIM to divide a wall/floor/roof composition into separate parts?

Are there any people here using a workflow from BricsCAD BIM to 3dsmax?

    What, really? AFAIR that's not so in Twinmotion. The other day someone said that SketchUp surfaces are not 'proper' surfaces as they have two faces so that they can have different materials assigned.

    Hmmm…not sure what I'm doing wrong with regards to twinmotion (via datasmith), because over there the same thing happens?

    Right … maybe I haven't actually tried that. So - it's a real problem.

    Hello.

    There is no way in Bricscad to split a 3D solid into multiple solids based on the plies from the BIM composition.

    Maybe using a specific 3DS Max plugin would help.
    Something like this one - https://www.frogsinspace.at/?p=4168
    Although, I couldn't find anything related to this approach.

    Hi,

    BIMDECOMPOSE will split a solid according to it's plies, put all solids in a block and classify that block as the original solid. The new solids get the same rendermaterial as used in the composition of the original solid. But the new solids are not bim classified and do not have a composition.

    There is no roundtrip, you can not recompose the wall and maintain its properties.

    Thank you Virgil and Piet,

    I've tried both suggestions, but the both don't give the desired result at the moment. The IFC-plugin loads the project correctly, but no plies are visible. I'll consider e-mailing Josef asking if he sees possibilities to create this feature. Maybe it depends on how the composition is written in the file?

    BIMDECOMPOSE creates the seperate plies, but it also deletes windows and doors that are in a wall compositon. Not quite the result one is hoping for when decomposing the solid ;-)

    Many thanks for thinking with me on this one!

    hi Joris,

    BIMDECOMPOSE creates the seperate plies, but it also deletes windows and doors

    That sounds like a bug but if you BMUNLINK first all doors and windows it works (they are no longer linked to the wall, and an actual subtraction is created)

    Hi Piet,

    I'll report it as a possible bug then. I'll try your BMUNLINK solution also and keep you posted here.
