Need help creating a complex mass ASAP!

[kim.74445]

If anyone can help me, I would greatly appreciate it! I've attached a sketch of what I am trying to model and I can't figure out how to do it using massing elements or walls. I need to create something that is flush at the building facade at 3 points as shown in the sketch, but then comes out about 2' at a point at the top above the building line. Please help!

Thank you in advance for any assistance you can provide me with!

There's two ways I could think to do it. The first is to create a mass and apply a wall "by face" via the mass. The mass can be made using extrusions and voids. Then simply click on the apply wall by face tool in the massing tool box and your should be good to go. Just a reminder that to edit the walls created by this method isn't typically very easy. You're better off editing the mass you created them by and then re-applying the create wall by face.

the second is simply the in place family tool. You could model the walls directly onto the face of the other walls. Use the voids and such to create your flush edges, etc. This method is a bit archaic in the sense that you're actually creating families. Be sure to assign the family category to "wall." Once created, simply join the new wall surfaces to the existing wall that's created, and any window penetrations will also penetrate the new mass/family you created.

Let me know if you need additional detail beyond what I described. Sounds like fun!

Cheers

The problem that I'm having with creating the mass, however, is that I can only edit it in a plan view. I did a solid blend so that I could modify the top and base independently, but I can't edit the elevations and change the cut profile or anything. I have no idea how to create this mass when I can't edit the mass in anything but a plan view!

You need to add more mass or void to modify the shape

Create this in Sketchup (free version) and bring back into Revit Massing and you are done.

I have no idea how to use SketchUp. Sad, I know!

here's an example of what you are attempting. Its about creating Masses of both Solids and Voids to get the shapes you are after.

Here's a trick: Solids and Voids can be placed on a plane created by a Ref Line. Ref Lines are different than Ref planes, and can be created while in Family Creation mode. This example was done as an in-place family mass. So here's the trick: Ref Lines can be rotated with geometry attached to them! If you create an Extrusion on a plane created by a Ref Line, you can rotate the ref line and the shape will rotate into a new plane. Ref lines have 4 planes: two to form an "X" with the center of the X being the "line" and then another plane at both endpoints perpendicular to the line.

Dissect the attached in place familiy, and it should help you out.

Oh, BTW, windows and doors wont cut both pieces at once, so you will have to do some editing to make that work.
