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.
If a truss is drawn that does not meet these requirements, an alert message is generated.
The width and height of the truss must be greater than three times the chord width
The truss hanging angle must be between -90° and +90°
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
