Changing the Trim Height of a System

The trim height of an entire system, or of portions of the system, can be easily adjusted. All associated loads, supports such as hoists, dead hang objects, and bridles, and connected objects also move with the adjusted trusses.

It is critical to change the trim height of systems with this method. Do not adjust the height by changing the Z value of a structural element from the Object Info palette.

Parameter	Description
Change	Select what to move when the trim height changes. ● Connected System: a truss or truss line, along with any connected supports ● Stacked System: a truss or truss line, any connected supports, and any objects stacked above or below the trusses, such as trusses stacked with truss crosses, or connected by hoists or dead hang objects ● Entire System: all connected trusses, supports, and connected objects
Value	For an absolute trim height, enter the height or distance value. For a relative change to the trim height, enter the positive or negative offset value.
Reference	Select whether the Value indicates a new set height for the system by selecting Absolute, or whether the system moves up (positive Value) or down (negative Value) by the defined offset by selecting Relative

Depending on the extent of the change selected in Change, the trim height of all, or a portion of, the hanging positions, trusses, and connected objects in the system changes. The length of some hoists and dead hang objects may increase or decrease, depending on whether they are above or below and whether the truss or truss line was moved up or down.
