View Full Version : Changing Beam Joins
Is there somewhere I can change how my beams join to one another. It looks as though they join to centerlines. I need this for a sloping roof condition. I have sloping steel beams (approx 5/12 slope) terminating into horizontal beams creating a shed roof condition for a clearstory/ light monitor. I want the top flanges of the beams to come together, but they do not because Revit assumes I want to joint these at the centerlines.
Hopefully this image is more clear. Basically, I want the join condition (blue grip) to be on the right side of the beam flange.

You might be SOL with RAC, which has always been limited in how it handles structural connections. Can you try not allowing the beam end to join?

You can fiddle with the end, dragging the blue dot of the sloping member in plan so that its dragged out to where you want, but it wont cut itself to join properly in section. Then the bottom most piece of it will be past the flat member, so to speak...
Ahh, structure in RAC, hehe...

Typically I'd drop the non-slopping beam, and add a shim or a bent pl to the top of the beam to pick up the deck. You should be able to adjust the end offset in the "z" direction to accomplish this. The end join function in RS won't do what you are asking either. You need to simply drop the flat beam.
I did manage to change where it was joined by pulling the grip in section view to the correct location, but the graphics rot as far as how the members come together - all hail the filled region and detail lines.

You could also try making your own w-shape in the family editor, and then use voids to cut the ends. I did this on a (residential) project with steel in it. Making your own steel shapes is like making your own doors in Revit.

Framing is still quirky in my opinion.
The only way I could get my framing to go exactly where I wanted was to place refernece planes, isolate and then move the grip. Technically this leaves each member floating rather than joined. but as you noticed, the joining functions are not the best.
