I have run into a problem with tagging joist elevations using the beam annotation tool. It appears that the "top elevation" tag does not work for joists.
I have a sloped roof system with wide flange beams and LH joists. I have created beams on the column lines, joists between. The beams are offset down to create the slope, and then the beams supporting joists are dropped an additional 5" for the joist seat using the "z-direction offset" tool. This allows connection betweent the joist and the girder to be maintained in the analytical model while the geometry is right for the joist seat. I then went through and tagged all the beams using the beam annotation tool. I set the beam elevation to display "top elevation", to not show when the elevation is zero, and to show elevation tags at each end of sloped beams. The beam type tag appears everywhere, but the elevations only appear on the wide flange beams.
When I switch the elevation display to "actual (selected) elevation" the joist elevations appear. The problem with this is that the beam elevations appear at the level offset, rather than the top of geometry. So the beams that are dropped the additional 5" for the joist seat are tagged at whatever the elevation offset, 5" above where they should be. Currently I''m tagging my project in two steps, selecting all the beams and tagging elevations with the actual elevation tool, then selecting all the beams and tagging with the top elevation tool.
I would like to know why revit is doing this. I'm currently working in 2013, and the last project I did with sloped joists did not have this problem. It seems like the top elevation tool does not work at all for joists in coarse view. In fine view I can select the top of the chord, but when I cycle to fine view the elevation disapears. This seems like an error in the way the joist family acts, but I'm not sure how to fix it. Has anyone else run into this problem? Any thoughts would be appreciated.
