We have a new Family for putting recesses in slabs.

It can be found in \masterdocs\cad\revit\Waterman Library\Families\Slabs and is called W_GEN_Square Recess.rfa

Once loaded it will appear in your project browser under Geneeric Models.

Once loaded you can drag and drop it onto your slab, but, the trick is to select Place on Face from your options menu.

Once in place you can resize it by using the drag handles or via element propertes.

Turn a Ramp into a Slab.

Use the Ramp macro to define the ramp.Define a level slab using the same plan profile. This will give identically vertical corresponding points, which can then be snapped onto the ramp using the warping function.Snap by clicking the either the blue down or up arrow (but not the square grip though) and dragging onto the corresponding point.Don’t worry about the following warning message. Once all the points are done, it will correct itself.Delete the ramp to leave the slab only.Now walls can be attached to the warped slab, openings can be cut and floor finishes added.

A very big thank you to Darren Snook for putting this together.

Holes in slabs and Lift Shafts etc ......

If you need to create a similar hole in your slab on several levels ie. a shaft the tool to use is Opening --> Shaft Opening

You can define the bottom and top levels of the shaft in the Properties.

One of the big benefits though is that you can draw in some "Symbolic Lines" ie: a cross representing a hole in the slab.
These "Symbolic Lines" will then appear everywhere your shaft cuts through a slab.
