Hi @Niranjan Das Sharma

I am not clear on your exact question. Anyway, if the elevator object bothers you, you could place cabin without the shaft, so you could model the slab and walls independently and thus have more control over the merging of your building materials.

Also you could take a look on this help article about element intersections if you need to:

They could be in the same layer and the layer Group Intersection Number is set to zero in the layer settings.

If so, they will not trim automatically.

Or they could be in different layers and each layer may have different layer Group Intersection Numbers, in which case they will not trim automatically.

Layers must have the same number for elements to trim.

Both have same group intersection number - 1. Both are reinforced concrete. - same material

It is very hard to say what is happening just looking at images.

Is 'Clean Wall & Beam Intersections' on? (I am guessing it is).

Sloping roofs will not connect to other elements unless you manually tell them to (right mouse click > Connect).

Yes got it.. i used roof without any slope to make a flat roof

I worked on another clean file with default template and with roof element its showing the same issue. With a flat slab its working perfect

I wasn't thinking you had used a flat roof as a slab, but that would explain why the 'flat slabs' were not trimming either.

Thanks for letting us know.

Barry.
