Truss Visibility Issues

[mrice.47661]

Thought I'd get this approach out there since I just spent a good 3 hours trouble shooting my issue and finally found a viable solution:

To get some LH joists to be visible in our architectural reflected ceiling plans, I had to go in and edit the truss family. Set your work plane to one of the default center planes and draw an "invisible" model line vertically. Then set up a reference plane above & below the reference level plane, constrained with a locked dimension (I used 9'-0" just for reference ... I haven't completely vetted what the fall-out of different offsets would be just yet). Then load the jury-rigged truss family back into your model - and voila - the trusses should appear correctly in plan.

This is a technique I'll use from time to time when making custom families from scratch if I'm having trouble with graphic display issues. It essentially gives Revit something to "cut" (the invisible model line) and that is apparently the lynch pin for getting the truss to display correctly.

Hopefully this is useful info for someone some day. Or perhaps even Autodesk - who could in theory add this invisible line to the stock truss families.

wild guess, check you lower floor plan underlay settings. if set to your upper framing level then the truss would show up to this level. I downloaded your truss and framed a upper level and it worked OK for me, did not apear in lower level.
Except when is used upper level as underlay, then it appeared. Then I could not clear underlay out by setting to none..?

I looked at this for about 2 hours, and think it is a bug with any truss with a curve.

Please see the doc file for description

a bow truss (or barrel truss, - I think any truss with a curve)
will appear in plan views below it if the arc is less than some factor I cannot understand.
Or.. shallow arcs will not show up in plans below, more complete arcs will.

furthermore, it is not consistent, you will see that one truss only shows half....

extensions on trusses are even more unpredictable, sometimes they will show, other times they will not
