Spot00056.pngTruss 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
