I am a revit structure newbie (long time autocad user)... We are doing a project that has bar joists brg. on cmu ICF and CMU walls.. the joists are higher on one end and slope to the other end... I can get the joists to slope if I do them one at a time, but if I try to do a system of them they are level with the floor.. 

 I will say I am very frustrated in learning revit, I am the head cad guy at our firm and I have read mastering revit structure and am just struggling in general.. People I talk to either love it or hate it.. 

any idea of being able to do these as a system..

you can put a reference plane and use it to create your beam system.

another way that I've done it (don't know if its a good way or not) is un-pin the joist and give the correct elevation in the properties window (start & end elevation). hope this helps

First thought- create a reference plane defining the geometry (slope) you want the top of your bar joists to adhere to.

Just re-name your reference plane (in the element properties box) after you've drawn it.

After you've renamed it- simply select the reference plane from the design bar when placing new beams and joists.  It will draw the joists along that reference plane.

In terms of making chages- make changes to the reference plane, not the individual joists.

You can also use framing systems to slope framing.  If you go to a section and select the system (NOT the individual framing members) you'll see a 'reference plane' show up.  You can rotate this reference plane by disjoining it (an option on the design bar) but I would not call this a preferred method.

Does that make sense?
