Can an object automatically cut a wall using its material properties?

Hi, I want to model the insulation strip that gets placed in a window/door opening and Purenit "pedestal" that supports doors and large windows on the facade. Ive scripted a custom GDL object as shown on the attached images but forgot to remember that objects cannot automatically cut trough construction elements using the objects material priorities (they are not shown on the attached Autointersect table). Is there a GDL command that would make an object cut other AC tools (slabs, walls, ect.) automatically so I don't have to subtract these objects from the walls using SEOs?

Another question: does anyone have any examples/documentation of how to make an object a subtype of another object (like a door handle is to a door)?

The result I'm pursuing is to to speed up the modeling for construction stage. If I can make this custom object, maybe even the adjoining concrete reinforcments as part of a window that would be great because I could model and detail the whole assembly in one step instead of 3+. I would also like to schedule all the components (window, insulation, concrete, opening size) with accurate quantities.

Suggetistons much appreciated!

Thanks!

If this is not possible (making objects automatically cut trough walls, ect.) is there another way to making such parametric assemblies? Hotlinks maybe?

The materials of an object cannot cut a wall. But, an object modeled with elements as you show (vs coded with GDL - which belongs in the Developer > GDL forum) can have a Window or Door subtype which will then cut an opening in a host wall - ignoring all materials of the object and the wall - based on a slab with ID "wallhole" that is part of the object if the opening is to be non-rectangular or is not to be the external bounds of a rectangular object.

I just saw that your post notes that you've scripted your object (vs modeling with walls/slabs and doing a 'save as' as an object). I'll move this thread to the Developer > GDL forum if you want a scripting answer.

Make it a window subtype as Karl mentioned above.
You can also check an object I created which does almost everything you need (except purenit base), with additional plaster layer and ability to use it with corner windows. For further explanation you can contact me directly.

Okay, thank you.

Would cutting a wall with an opening first, deduct the materials and then placing your object into it work ?

Miha, how do you place your object in the project? Using the object tool, via window settings (selecting the appropriate closure type) or something else?

Thank you for sharing

With window tool.

I used an approach similar to your recommendation in a renovation scenario (demolishing existing door, making a "virtual" new wall and placed the new door into it) which worked, was a bit messy (layers, schedules, display options), but acceptable because it was a specific situation. In the current case I'm looking for a more "minimalist" approach that would work in many circumstances.
