How would I draw these shapes?

[comical_wenger]

Hey guys, I am going through the family tutorials looking at drawing different shapes (extrusion, blend, sweep etc) and can not figure out how I would draw the shapes on a model I have made (I assume this would be done as a conceptial mass aswell?)

Here is a photo (its more the triangular parts at the front, i can do the boxy main part with a blend), help would be great....

they look like roof shapes to me with voids (parallel to face.)

the vertical shaped walls could be done by editing a wall profile?

Looks like a lot of roofs, so that's how I would probably build it.

[comical_wenger]

and how would that be done?

[Kiteman48]

Start with Rectangles in plan. Give them equal slopes for each triangle, in opposite directions.
Then Trim with Voids. When you get to valleys use the same void to trim the roof but mirror it. Use copy and paste in place to get exact alignment.

Another way would be to extrude from front to back and then cut at intersections.

It is a little complicated either way.

What it boild down to, is you're getting into a shape that is not Revit's strong suit.
You refer to creating a Family in your first post, but this is more of a Conceptual Mass.
Assuming you're in Revit 2010, this is a job for the Conceptual Modeler. You should be able to create an outline of your form in Plan View and then push and pull the vertexes and edges to get your triangles.

These shapes are trivial simple to build if you think of the space the roofs contain first. DaveP and I are probably saying the same thing. To reiterate:

Model the negative space to be covered with roof using a mass. Build multiple solid forms, being sure to join geometry to let Revit determine the intersecting faces. Apply roof objects using roof by face. You may have to create the center faces as separate roofs, depending on the acuteness of the incident roof faces.

I understand what you are saying by modelling the negative or inside space but the thing is im not really sure how I would do that. I can create the shape in plan I guess but not really sure how to do the vertex push/pull etc.

Its asking a lot, but if any of you have any spare time, could you maybe give me some step by step screenshots?
thanks so much!!

Roof with spot elevations. :)

I doubt Revit will create a roof on top of the mass without errors

I think you are prolly better of by either following Phil or create it as an inplace family

[comical_wenger]

how do the spot elevations work?

Hi

I have posted a little demo video for you.

I think this is what Phil means. Be aware that the more steep the slopes are the more thin your roofs get. They don't ofset the roof thickness.
