This is The Official Cosmic Truss Tool Box and it is completely FREE! If you are a rigger or a roadie and plan to work with Cosmic Truss System for your truss constructions, this is the must have App. Inside the Tool Box you will find these useful tools for your truss job. The CT Load Master The CT Load Master calculates the single point, uniformly distributed, and third/quarter/fifth point load of your Cosmic Truss System, when you enter the span of your construction (Metric/Imperial). Actual weight of the truss is considered in the calculation. The CT Level The CT Level is a useful water level tool that assists you in checking if your truss construction is leveled. CT Augmented Reality Our latest and most awesome feature. Scan the Codes in the Cosmic Truss catalogue and experience our couplers in Augmented Reality! More tools and languages will be available in further updates. Stay tuned for more Cosmic Truss tools and if you have ideas for tools - share them with us: support@cosmictruss.com
