This should be simple, but I can't figure out how to place exposed beams under my sloped roof assembly. It seems my only option is to pick a beam from the structural design bar and than place it on a plate height level (see left side of attached file). I'm not able to slope the beam from the level it's placed on. Rotate on the toolbar did not work.
The beam was placed in the project from a library family (.rfa). Can family element even be sloped?

A beam has to attach itself to a working plane which is currently your level placed. You can create a sloped working plane in a section or elevation view and label it. Then when you go back to a plan view and select the Beam command there will be a pull down selection box in the "Plane" top bar menu to select your named reference plane to attach to.

Create the reference plane first!
Thanks Rythmick, I appreciate the help.

Rythmick, one other question? How do I vertically cut the ends of my sloping beams? I tried to do that by editing the family, but it did not seem to work.
Thanks

You can use a void in the family editor.
Not sure what you are trying to do but I've created exposed beam rafters quite easily using the roof tool to create the beams. You can make one beam then array, copy or mirror the rest. A roof by extrusion in a section would give you the existing roof lines to work from.
There are other methods also, like making them from a curtain system, using blank panels and beams for the mullions.
You can make the beams with in place solids and voids also.

I don't fully have a handle on the void tool. I can see using the void tool on the upper portion of the sloped beam, where I want to cut it back to a verticle cut, but than would I use use the extrusion tool to add to the bottom of the slope beam, where I need a verticle cut aligned with the roof overhang?
You can specify a plumb cut while in roof mode, can the same thing be done for the individual beams?
Thanks again for the help.

You would need to make the beam longer so you could use the same void proceedure. You could set that up as an extension in the family.
You can control the void angle cut by creating an angle parameter with the void. I am not aware of a family sketch tool that would default the void line to vertical at any angle.
Consider using the roof tool to create your beams as I mentioned above. Then you would have the vertical cut control.

Editing the beam in the family editor worked, thanks. Now how do I get it to display on my model? I uploaded the beam with the end cuts back into the project, but the model did not update. So I earesed one of the beams at the section view, redrew it on the plan view, and it displayed as before, square ends and not verticle cut.
what did I miss?

Okay, this is weird. I'm stretching the beams to align with the roof overhang, and instead of stretching, it adds another piece of roof beam on the otherside of the void creating my verticle cut.
The family editor has 3 reference planes at each end of the beam, when looking from the front. Is this a case of to many reference planes? My voids are at the edge of the center reference plane on both ends. Neither end comes close to reference plane Left and Right at the farthest ends.
I'm not entirely clear on the fine points of the family editor. I'm looking for a tutorial that explains more than what comes with the Revit tutorial.
