How to cut a chamfer into a slab using profile-reveal family

[SGartz]

Hi, Revit newb here. 

I am trying to add a chamfer cut to a concrete slab.  I have created a new family using 'profile-reveal' and made a 25x25mm chamfer.  Now when I go to my slab and add the slab edge, instead of cutting the shape out it is instead adding the shape.  How to I create a slab edge that would cut the profile from the slab?

Try using a Slab Edge with a Profile Family that contains the chamfer.

...or an in-place void sweep to cut the edge.

Thanks. When I click on the slab edge and try to select another option I only have 'Slab Edge Standard'  could you explain what you mean.  Sorry, I am a newb.  I've had a good Google and I'm still none the wise, the penny hasn't dropped yet...

Are you familiar with Profile Families? There's one assigned to your Slab Edge Profile. Look under it's Type Properties and you'll see which one is assigned. Are there any others available in the drop-down box?  Check it out.

...you know, @SGartz: I would just use your Profile in an In-Place Component Void Sweep pathed along the Slab edge. You can then Cut the Slab Edge with it.  Have you done anything like this before.  Pretty simple.

See screencast for using a Slab Edge.  Of course, your floor footprint needs to be smaller than the final dimensions to accommodate the added edges.  Similar technique with using a Void Sweep, but subtraction instead of addition.

I do have those option, but that's where my new Chamfer I created is.  I just wondered if I could make this profile extrude a cut instead of a solid.

No but I can try this,  I'll experiment and void sweeps.  I'm an Inventor 3D man usually so I need to get used to a different way of thinking!

Thanks for the video. wow you are really slick on this!  I'll give this a go!

You can mark both @cbcarch and @barthbradley posts as solutions as well to be fair.

Here's using a void sweep in an in-place model to cut the slab.

Ah! I see! You're not actually adding a chamfer edge; your try to cut a chamfer edge.  No can do with Slab Edge.  But you can definitely use your Profile in an In-Place Component Void Sweep to cut the edge.  That's the way to go here.

Slab Edge with a Profile that has a chamfered corner. Click on slabs and apply.

Less messing around with Cut Geometry, in-place modeling of voids, etc.

Just my 2 c worth.

That is good idea to use void sweep in place, but I don't want to use it every time I need a chamfer. Isn't there a way to use a family instead that would automatically update itself depending on the edge shape or slope any?

How would one continue a finish around this slab edge nib?
