How to hide these slab lines which is making my 3D view

Hi,

Can someone help me hiding these lines (slab edges)? I have tried to play around Visibility Graphics but didnt find any luck. Masking and Region doesnt work in 3D views. Please see the attached picture.

Join Geometry - in the correct Join Order.  

...if they still show, then either the Floor Edge is not  flush with the Wall Face, which is correctable by aligning, or the Materials differ, or the Wall Layer that covers the Floor Edge is too thin, or...heck, just post the file and we'll tell you exactly what's going on.

You need to set the floor boundary back behind the exterior finish layer of the wall, then change the Base Offset (or Base Extension - if you unlock the exterior finish layer) of the wall above the floor, or the Top Offset (or Top Extension - if you unlock the exterior finish layer) of the walls below the floor, to cover the thickness of the floor, then join geometry if you want a clean section cut.
