See the rig before you build it

Open an .mvr and walk the whole scene in 3D — nothing to install.

  • Drag in an .mvr and the full rig renders in 3D — trusses, fixtures, and layout
  • Fly through it, or switch to Top, Front, and Side plan views — sanity-check trim heights and layout
  • Click any fixture to read its patch, mode, and GDTF geometry
  • Sign in with your own GDTF Share account to pull the latest profiles
  • Nothing uploads — your show file stays on your device

The biggest additions this fall.

Check

Rig Check

Flags address overlaps, missing or placeholder profiles, modes that don't exist, unpatched lights, and duplicate IDs. It re-checks as you edit and prints as a report.

Compare

Compare revisions

Load the older file and see what was added, removed, moved, or re-patched. Show only the changes in 3D, or print the list.

Edit

Undo and redo

Moves, rotations, patch edits, mode changes, and deletes all step back and forward, and the app warns you before you lose unsaved edits.

View

True plan views

Top, Front, and Side views drawn without perspective, with fixture labels by unit, ID, address, or name.

View

Layers and classes

Show or hide whole layers and classes in a click, so the roof stays out of the way of your plan view.

Export

Measure and share

Click two points for a reference distance in metres and feet, then export the view as an image.
