I have 5 different trusses on my project. Everyone I made needed to be "fine tuned" for one reason or another (some a lot). After adjusting them and getting them right I locked the truss envelopes and went into the floor plan to move them around for 24" centers and to multiply them where needed. As soon as I moved the first one, I noticed in my truss cad detail that the truss changed back to the way it was originally when first made losing all the changes I made even though I had the envelope locked. Is this the way it should work? What's the use of having the "envelope lock" if as soon as it is moved it changes back? Please tell me there is a work around to this or did I approach correcting the trusses all wrong?
