Hi guys,

I'm trying to understand the differences about trim height of truss system and z coordinates of hanging positions.

I can explain better with this example:

I draw a simple truss system with two hoist, then I select and change  the trim height of the system at 6 meters.....ok .

I convert my truss to an hanging position (T1) and in OIP I see  Z=6m

Then i change again the trim height of System (relative -1m entire system) but my hanging position still have the same value that is 6 meters.....but that isn't true, it is 5meters!

Also when I edit my hanging position, the Z coordinates of my trusses is -1

Now I have two reports about this truss with two different height coordinates ..........

I'm a little bit confused, which is the right approach to this???? there is a method to unified this measurements?

I hope I'm making clear.

thx

This is by design. The Hanging Position exists for when you need to group multiple elements into a single named position. Otherwise, you can attach lights, etc. directly to truss. The Hanging Position as a whole references the z height of the object. The Change Trim Height command is so you can change the height of the system inside the hanging position without affecting the trim height of the position itself.
