Precast split floor to hollow core slab.

edgarsceplis09 — Tue, 16 Jan 2024 22:08:11 GMT

Hi, i need to split my 300 mm Generic concrete floor to hollow core slab. I marked my floor as structural element, i founded a hollow core slab family, and when i try to split. I got a error message: Hollow core slab with invalid thickness. Change the selected template family in Config or adjust the thickness of the slab to match. Maybe someone can help to solve the problem? I tried to make my generic floor 500,1000mm and thats didnt help.

Please review the following;

It appears you can only use 200mm a slab thickness with the OOTB Families!!!

I did have a play and placing in a 200mm and then editing afterwards to 300mm and clicking Cancel will give an output but probably not a full solution.

As a Caveat, if you do not need to use it for Precast Design but more Structural representation i would recommend using a Structural Framing System with Precast Structural Framing Components as this shows the oblong voids as you would expect with deeper slabs
