Beams who are locked to two beams on different levels

[Anonymous]

Hello all, I'm not new to the forum, I've just never made an account to actually make a post! 🙂

Anyway, I'll explain my question. I'm currently working on a home with 7 roofs, whichs the height of start and end variates in height. They're made out of steal structures and are like trapezium shape (a traingle with the top cut off). 

So there are two beams that are attached to certain levels (Beam A is on level 1, Beam B is on level 2, both completely horizontal). Then there are two beams who are connected to those two beams whichs means they are on an angle going from level 1 to level 2 (Beam S1 and S2). 

I want to make sure the beams on an angle (beams S1 and S2) are moving with beam A and B because they are the 'hosting' beam which are able to be changed.

I've tried to make it work with using Coloms and attach beam S1 and S2 to those coloms, then its works! But I don't want those coloms in all 4 corners since that's not the structural design.

So Is there a way to make Beam S1 and S2 locking to Beam A and B so that I don't have to change the height of those every single time I change the height of Beam A and B.

To make it more clear I've attached a project.

Hello,

Here column is used as main intersection point for the beams so if you change the height of the column it automatically reflects for beam as well, without using column we don't have any node reference for the beams.
Changing of beams heights on different levels can be done by manual method in the attached Revit model i noticed you are using start level offset better select two beams at a time then you will get "Change join end level offset" just enter value it works.

Disallow join for both ends of the A and B beams then S beams will move when A and B change elevation.

I tried both solutions. But both didn't make me get what I needed. 

What I just need is that my beam's A and B are changeable in height using the move tool on the level they're on.

It somehow works for all 4 corners of the rectangular roof except one corner, that one corner stays on its original location. Anyone knows how this happens?

In my screencast I'm showing the problem. I have to manually change the 'Start Level Offset' and then I can let the beams be changable by moving levels up and down.

But I have to do it exactly how I'm showing in the Screencast... Weird

In the screencast posted below I'm doing the things and steps I must do when creating a rectangular beam structure that I can change in height using levels specificly for that top and bottom part of the structure.

I have to change 'Start-/-end Level Offset' in order to make it stay on the level whenever I start moving it up and down..

So is there a way I can make the greyed out part of the reference plane be black text and not having to add up and take to make it being able to move.

See the video what I mean.
