    Lock Offset Reference Planes without Dimension

    Is there any way to lock 2 reference planes without using a dimension?

    I'm thinking I could actually dimension it, but create a new dims style and hide it so it's not in the view? If that's even possible.

    Take a look at the image. I want the entire roof system to move when I adjust the level. But, I don't want the dimension to show up.

    I added a named reference plane and inserted my beams and purlins on it. That works as it should, but the roof can't be on a reference plane.
    I put the roof on a level and have one end to define the slope.

    If I move the level, the roof moves. If I move the reference plane, the beams and purlins move. Any ideas?

    This is one reason why I would like to lock offset amounts as stated in the other recent offset thread...

      I dont use a RP for my beams. I manualy adjust the heights with offsets to the level they are places on. I also use floors as my roof elements. My floors are attached to a level with a slope arrow line. The slope arrow line controls my roof heights off of a level.... I then will apply a offset to the floor depending on my floor types total thickness. Did that make sence? This way everything is controlled off of a level. I normaly have this level be TOS, FF, TOC, TOS @ 2nd FF, ect ect ect... It is not a live reference level so no plan views.

      just my 2 cents. Let me know if you get it. I can take some screen shots if you would like.

        I just stumbled upon how to do it!

        Okay, it's pretty difficult so to try to keep up. I'll type really slow................

        Delete the locked dimension. That's it! lol

        Once you lock a dimension and establish a constraint, if you delete it you get a warning to either unconstrain or leave the items constrained.

        It works perfectly and there's no dimension. Sweet. Also, if you need to unconstrain it later, there is an extra padlock where the dimension used to be. Just unlock it.

          I sort of get it. But what is the advantage of doing it this way?

          And why do you use a floor for a roof?

            You move your level and everything else moves with it, and your beams hold there offsets. Plus less RP lines all over my project. they get annoying.

            Roofs can not have a deck profile, that I am aware of. We only use a roof if it is curved.

              You can also do this to constrain EQ dimentions on bay spacing, if your not using beam systems of course. I tend to not use beam systems towards the end of a project.

                What if the height of the purlins change? then you are in trouble with this system of two reference planes locked by a dimension. Another approach is to set the work plane of each group of elements in the roof and structure assembly to the bottom of the elements above. Then if the first element moves (the roof level or slope), all of the elements below move along.

                  Oh, okay. I get it. The main reason I use a reference plane is because my beams slope 3/8" per foot. It's the way our roof systems are designed. Rather than figuring it out every time, I just slap a RP in there and place the beams on it with the Z justification to top, and the purlins with the justification to bottom. Then, I go to my plan view and offset my purlins whatever spacing I need and they stay on plane. That just seems easier to me.

                  Can you shoot me a screen shot of the floor with a decking profile used as a roof? I may start doing that.

                    DOH! Never thought of that. It doesn't give me an error, but I need to unlock and manually adjust the roof plane. See above, I was using one plane for both the beams and purlins. I think that's the issue. I add a plane like you suggest and see what happens.
