Curtain wall components (mullions / panels) assembly code #412

Open WillemdBr opened 2 years ago

WillemdBr commented 2 years ago

Hi,

When a wall is drawn with a curtain wall, and walls and windows are the Curtain panels, those panels should be classified differently, using the Assembly code. In IFC these components always have the same Classifications, which is the Assembly code assigned to the curtain wall. So the IFC doesn't use the Assembly code assigned to the curtain panel components.

Can this be fixed with the IFC exporter for Revit, or is this a IFC specific problem?

Regards,

Willem

I think this should be fixable, if I understand correctly that the panels and mullions are using the Assembly Code of the curtain wall instead of their own. We will try to reproduce this.

Thanks Angel. And yes, you've understand it correctly.

I don't see this happening in the latest code - I exported a curtain wall with a wall type in one panel and glass in another. Both had assigned assembly codes. On export both of those codes were there. I'll try it in 2022 as well... {edit} Same thing in 2022. Willem, which version are you using? or maybe I misunderstood the issue.

Hi @parrela, I'm using version 20.3.2.0 for a Revit project which is still in 2020. @AngelVelezSosa Can this version be fixed? The project on which we're working on is a government project which has BIM guidelines such as the Assembly code.

TEST.zip Here is the R20 file so you can test.

@parrela can check to see if this is still a problem in 2022/3. We won't be doing any (non-critical) 2020/2021 updates, especially for export, since the workaround is always to temporarily upgrade to the latest version and export from there.

@AngelVelezSosa I can't reproduce this in 2022 or 2023.
