Stop guessing. Start rigging.

Know your limits before you pull the motor.

RigThis: The Professional Rigger's Physics Engine.

If you’re a rigger, production manager, or arena tech, you already know “close enough” doesn’t fly. RigThis runs the heavy physics for bridles and truss loads and hands you clear numbers fast, right when you’re on the floor making calls.

RigThis home screen: calculators, Pro upgrade, and tools

Built by riggers, for riggers. It takes the ugly arena-floor math off your notepad and puts it in your pocket, so load-in stays safer and faster and you can keep your eyes on the rig instead of a spreadsheet.

What you get on the deck

These tools match how we actually work: beam geometry, baskets, offsets, and what the venue will sign off on. No generic textbook problems dressed up as rigging.

  • Bridle solvers

    2-leg in the base app. 3-leg Pro

    Punch in beam heights, baskets, and offsets. Leg lengths and tensions update in real time, with barycentric-style weighting so the shares line up with how you hung it.

  • Safety-first analytics

    If leg tension, point loads, or bridle angles (think 60° and up) step past venue or industry limits, you get a red alert before you’ve committed steel in the air.

  • Dynamic load distribution

    Lay out truss with movers, video, and stacks in mind. Use Dynamic Load Factors (DLF) for automated moves so shifting weight doesn’t sneak up on your motors.

  • Projects & saved venues Pro

    Pro unlocks projects so you can maintain multiple venues at once, each with its own grid heights, ratings, and room-specific details. Nothing gets mashed into one generic profile. Create, rename, and file jobs so the right building comes back when you walk that room again.

Who it’s for

RigThis is for people who hang shows and have to back up their numbers in the room, not bury them in a spreadsheet nobody trusts.

  • Headline riggers & high steel running bridles, motors, and mothergrid picks where the angles and tensions actually matter.
  • Production managers & PMETs who need clear outputs when structural, the house, or the tour asks “are we good on that pick?”
  • Arena & venue techs working off rated points, grid heights, and paperwork that changes room to room.

Tours, broadcast, corporate AV, festivals, houses of worship, anywhere the grid is a real constraint and load-in time is never as long as you want.

Venue hub: saved specs and calculators for bridles and load distribution

Physics engine, not a toy calculator

On the phone with structural or production? RigThis gives you plain numbers, cautious flags when things look hot, and assumptions you can actually point to.

  • Resultant side pull shows when horizontal components on baskets and span picks deserve another pass.
  • Barycentric coordinates keep multi-leg load sharing tied to the geometry you actually typed in.
  • Lever rule is there for quick moment checks when weight slides along a beam or truss.
