Hi,

I'm trying to model a roof/ light tray profile. I have been able to figure out how to model the pieces with the flat bottom plane and sloped top plane using the point edit tools (although it is hard to be exact as they don't seem to snap to anything...)

However, I can't figure out how to model the upper roof that has a sloped bottom plane and flat top plane. Any suggestions...Am I just missing the edit points? They only show up along the top edge.

AFAIK you can't use both the standard slope and the point edit tools (which are only on the top) so what you're asking is not possible. You could use a void to cut it if you want, or use the methods below.

I'd do it one of three ways-

-Standard generic family, wall hosted, for the entire light shelf. Perhaps could be nested with the window. Most time up front but if there are a lot of them would be the easiest to revise.

-In-place roof family done as a sweep or extrusion. Acceptable if this occurs in only a few places in the model, but would be a serious pain to revise unless it was all done using a profile you could change.

-Model upper portion of eyebrow as a roof and lower portion as a ceiling, and use a wall or fascia to connect. This is the "model it as it's built" method but is probably the hardest to edit quickly down the line if there are multiple instances. Also easiest way to get multiple finish and substrate layers to show up in section if necessary.

Thanks for the suggestions...It would be nice if you could change the orientation of the objects, i.e. allow the top plane to be flipped to be the bottom plane...I'm sure that has multiple other issues....

I like the 3rd suggestion once the design is a little more set (detailing, dimensions, etc.). For now, I'll either try the first suggestion (can that be an in-place (live in the model) family or do I have to create at it as I would any new family). What about massing? Could that be an option?

If all else fails, I'll just move into Sketchup to do some quick studies and then take the final profile back to Revit.

Thanks

An in place family is fine as long as it only occurs once - you can't do instances with in-place families so if you copy it makes an entire separate family. If you have multiple windows with the same shelf I highly recommend making a separate family.

It's also inadvisable to use massing for actual physical objects, for a variety of reasons you can find out by searching the forums. You could use massing to make a form that you make walls roofs and ceilings out of, but that seems a little too complicated.
