Gdl components ifc mapping

Ahmed_K — Sat, 10 May 2025 13:52:24 GMT

Hello,

In our national standards, we should set a separate classification for some windows and doors parts, like sunshades, lintel, sills.

Since gdl objects have only one class by object, is there a way to set a class (by selecting the class from a list or write it manually ) , and map that value to ifc ,

Any other idea is welcome,

Thanks

This is a big missed opportunity that GS is not tapping into, lets call them "assemblies", where we can manage relations between elements properly.

I have no other workaround than recommending to actually place different elements as discrete objects, even tho the effort and modeling cost raises tenfold. 😞

Absolutely agree,

Actually, i use propreties as a secondary classification of components, but it leads to errors if you don't be carefull with your model.

or GS please just make a link between properties in gdl with the properties in the project: if the object has a property "myProperty" and "myQuantity" whatever the names it would give the input for the property in th project (a special deriving command in the calculated properties should come), otherwise "" or "0".

Same thing for the gdl commands - with the same logic.
