Hello

 

I am trying to adjust a list someone else created and I am wondering where he/she found "DIN Berechnete Fläche" (DIN calculated area). When i type it in search tab it is not shown ....

 

Anyone knows? 🙂
Thank you!

Hi Laszlo, thank you for all this recommendations on how to build the wall:) It would make sense, but requieres some work, which I would like to avoid. I also like to keep the wall as a wall element as a whole. May I ask btw, why do Curtain Walls and Railings not extract from the Wall? It doesn´t work even if they are built of material, which have higher priority? I am asking because the railing would make the most sense to me, because it is easeier to change then individual colums.

 

So about the wall with columes, that looks like this

I still prefer the idea , where I simply define with the formula on lists how much % should be calculated as wood and how much % as insulation. We don´t need to draw so detailled in the plas, but only seperatly as a detail and that is much faster.

 

I will learn more about Property manager formulas and try to figure it out 🙂

If you use a composite wall then using expression based properties to sub-divide a single skin volume in a 1:9 ratio might not be possible, or, better said, not easy, as properties are based on an element level, which in your case is the whole composite wall. 

While you can extract each skin data in schedules, this is sadly not possible with properties.

I think you'll have to follow @Laszlo Nagy  advice and model this studs to get the desired result within Archicad. Or export the wall skin schedule to excell and divide the insulation volume with a formula into two separate materials.

Thank you Miha and Laszlo for your explanation! Now I am convienced and will model the wall with colums 🙂

The reason Curtain Walls and Railings do not subtract themselves automatically from Walls is that Priority-based Connections are not implemented for them, that feature works automatically only for the intersection of certain element types, likes Walls and Columns, or Walls and Slabs:

So, in such a case you would have to perform Solid Element Operations to subtract the geometry of the Curtain Wall or Railing from the Wall.
