drill3d.com
The operating system for the marching arts.
One serverless platform for show design, rehearsal, and adjudication. Built for high schools, DCI corps, and WGI ensembles, on desktop and mobile.
Design in 3D
Write drill on exact HS, NCAA, NFL and WGI geometry. Snap to quarter steps, check spacing, and hand the show to Unreal Engine 5.8 for cinematic renders.
Dot books that play
Every performer gets their coordinates, step sizes, and a count-synced audio player with their section stem or MIDI part. Phone, tablet, or web.
Judge tapes, transcribed
Adjudicators record from their phone. Drill3D uploads to R2, transcribes with Workers AI, and summarizes feedback by set and section before the buses leave.
Real-time co-authoring
Designers, arrangers and directors edit the same show at once. Durable Objects keep everyone in sync with per-set and per-dot locks.
Venue presets
Every field type is modelled to the inch. Dots are always written against the drill hash, even when the painted hash differs (DCI at Lucas Oil Stadium).
