Structural Floor Slab with Multiple Slab thicknesses

[brad_witt]

This is a wish list item for Autodesk. My company models a lot of parking garages with two way slopes. When the structural engineer designs two or more different floor thicknesses there seems to not be an easy way to add points, and slope the floor with all the different thicknesses sloping together. It would be nice to be able to create a single floor slab and be able to create different thicknesses within that single floor. See the attached image for an example.

You can work your way around this by modelling different floors/slabs with different thicknesses. 

and I totally agree with you it would be highly beneficial to be able to manipulate different thicknesses within one floor object, but the way the developers might add this feature might allow changes with sketch lines and boundaries which is the same procedure as modelling multiple floors/slabs each with its own thickness.

Correct. That is the only way to accomplish the multiple thicknesses in a design is to model separate floors. 

When I saw the improved split lines and fold lines with R23 then it tells me that it could possibly be done and is headed in the right direction. When you have two different slab thicknesses as their own independent element, when you need to create the slope and the thickness change is in the middle of the slope it take a lot of time and effort to get the elevation at the transition aligned.

Of course you can do it with a single thicker floor and use shaft tool to shave it off to create thinner area.

Thank you  ToanDN. Any suggestions as to how to accomplish this when the slab is sloping?
