curtain wall area not correct

agroni

Hi,
I am having a bit of a problem with extracting the area from a curtain wall.
It is modeled as one piece in Archicad and exported as an IfcCurtainWall as an IFC2x3. In Solibri it shows the area of only one side, but not the other?
The parameter that I chose is gross area.

Any idea of what is happening here?

Hi @agroni

I was able to reproduce this issue with the file cw.smc of a curtain wall I drew using the chained poly-line, which results in an L-Shaped single curtain wall.

Solibri is only calculating the length and area of the longer side of the L-Shaped wall.

I’ve sent this to our development for investigation. Would you be able to split the curtain wall into two separate lengths so that 2 curtain walls will exist with their individual lengths/area?

Hi,

I’m looking forward that Solibri one day corrects this issue too

By my experience it happens to all elements that have more than one plan or chapes in two axes.

While we wait my suggestion is to calculate the area of the child elements (plates, doors, windows, …) that are in the curtains walls. This child elements might have a small overlapping with the frames but I believe it can be a good way to control the total area.

@john-lipp
thank you for investigating this case.
There is always the possibility to built bits and pieces. The point of modeling polygonal elements helps quite a lot in the early design stages, where components must be changed multiple times.
Therefore, the possibility to extract the correct data from such components would be helpful.
