Parapet or Something Else?

Anonymous — Wed, 13 Nov 2019 22:48:30 GMT

Hi Y'all,

I'm currently working on modeling an existing building for my work and am having some difficulty with the roof line. The roof (I believe) is actually just a "flat" roof with a parapet around the tops of the walls.

In the images attached you can see shingling that goes around the top and down the side of the building and around the windows. The idea from our client is to change this out for standing seam and cut the line above the windows. I've notated where we're cutting the line with red in the attached images. What is the best way to model this? I'm thinking as a parapet, but perhaps there's a better way?

There is also brick detailing on the front of the building that I need to duplicate notated with blue lines. What would be the best way to model this? A line based family?

Thanks in advance for your help!

You could model it using the Roof tool as well.

And just make the offset negative so it sits on the side of the building?
I was originally going to do it as a roof but wasn't sure about how to have it interact with the wall?

You can model it as a fascia.

Just looked up a video on this. Seems like a great idea! Thank you.

Any idea's on adding the decorative brick arches to the front of the building?

Modeling it as a Roof is just one approach. May or may not be the best approach. I figure it's probably stick-framed. Rafters and soffit. I'm thinking of something like this:

It's basically that. We opened up one section a couple weeks ago when we were onsite to see if the CMU block continued up underneath it - of course it doesn't. But it is definitely a soffit.

Sweep.

Yeah. It's a mansard roof. Ever been to Beverly Hills, CA. They're all over the place.

FWIW: The simplest and quickest way to model a mansard in Revit is to use the "Cutoff Level" property -- at least for the initial construct.

There are multiple ways to model the brick arches:
- Wall with edited profile
- Roof by extrusion
- In-place model extrusion or sweep
- Family (wall/face host), if you need the arches to be parametric

Spent plenty of time in L.A. but I guess not so much in Beverly Hills specifically.
This was brilliantly easy! Thank you.
