The tutorial below if for Revit 2009, if you are using Revit 2010 try the new interactive video tutorial above!

A slab toe or a slab edge" as its known in Revit 2009 is one of those hidden away commands that isnt obvious unless you know where to look. The basic process for creating a slab edge is as below.

• Firstly go into a 3D View, you will probially noy have a good view of the slab as other components such as walls etc get in the way, to help us get a good view of the slab, we must hide the other components.

• Select all the elements you wish to hide, (press Ctrl to add components tio an existing selection) them goto the bottom bar abd click on the Tempororaly Hide/isolate button that looks like a pair of glasses. Click Hide Elements (higlited below).

• You should now have a clear view of youe slab (as below). The hidden components are still there, but hidden in view, we know there is hidden components because the screen edges turn blue to higlight the fact (as below). This menthod of hiding components is not the same as the Hide in View Command, the diffrence being that the objects we have just hidden are still there in view and will still print in the view etc. This method is used to make navigating around your model easier.

• Rotate to a good view of your slab (underside is best), then select the Floor Slab Edge tool from your design bar (as shown below).

• Select the slab edges that you want to apply the slab edge to, working your way around the slab. Ensure that you pick the bottom edge of the slab, as highlited below. Revit will let you select the top edge, but the dimentions and offsets will not work properly.

• That is the basic process of adding a slab edge, however you may notice the material needs adjusting to match your slab material to make the slab and edge one monolithic structure with teh same hatch.

• If you cut a section you may notice that some of the walls do not connect properly with the slab and slab edge as below, to fix this we must use the Join Geometry tool, and select the objects to join, i.e. Slab & Wall, Slab edge and wall.

• Once you have used the Join Geometry tool you will get a correct cleanup as shown below.

• if you have lots of walls, you can also use the Join Geometry tool in 3D view to select and cleanup your components (as below).

Theis is the basic method for adding a slab edge, you can modify the size and shape of the edge by going into its properties. The slab edge is a profile that Revit Sweeps around the edges you specify, you and create your own profile shape if required.
