Lock Truss Envelope and Webbing not working?

[Design20]

Just upgraded to X15.  I don't know if this is a bug or not, but when I check "Lock Truss envelope and webbing" on a floor truss and then I move or copy the truss, all my manual edits are lost.  I've tried all the various combinations of those four checkboxes on the Truss spec dbx, and I can't get my edits to stick around.  can anyone tell me what I'm doing wrong?

Didn't look at the file, but were your edits to the envelope or to the chords?

I edited the chords/web members.

 

One thing I figured out is if I create a truss, lock the web, multiple copy, then edit the truss, only one truss with that label changes (not even the first one weirdly).  if I then check "Force truss rebuild" on all the trusses with the same label, my edits are reverted back to the default, BUT if I hit undo, all the trusses with the same label change to what I had edited.  So I'm pretty sure this is a bug, but at least there is a workaround, albeit very specific and clunky.

The truss envelope can be edited in section view.  In truss detail view, you can edit the envelopes and chords.  In my experience the only edit that  sticks when copying   a truss is an envelope edit that's been locked.

When I looked at your plan, and then your saved section - I edited that floor truss via the CAD Detail (removing the cross members).  Made a copy and it retained the edits.  Is that what you are after?  

 

This was a simple edit where the truss was the same length.  More extensive edits would be required as the truss lengthens or has other changes.

Scott,

 

I tried it again today, and everything worked fine and as expected.  I have no idea what I was doing wrong or differently before.  weird
