Truss Configuration Requirements

A great deal of flexibility is incorporated in the Spotlight truss object. However, in order to create a valid truss, the wide variety of configurations leads to certain restrictions in the application of truss properties.

 

Truss Requirements

The width and height of the truss must be greater than three times the chord width

The truss hanging angle must be between -90o and +90o

A triangular truss must form a valid triangle

The chord diameter must be greater than zero

A pre-rigged truss cannot have lacing

A pre-rigged truss cannot be folding

Only box trusses can be pre-rigged

A folding truss cannot have top lacing

Folding is not allowed on a stacking truss

Top lacing is not allowed on a stacking truss

The top brace diameter must be less than or equal to the chord width

The side brace diameter must be less than or equal to the chord width

The connection interval must be greater than the ladder bar spacing

Ladder bar spacing must be greater than three times the top brace size

If the section is too small, lacing may not be drawn

If a truss is drawn that does not meet these requirements, an alert message is generated.
