Explode Body (View Transform)

Status: Implemented

Explode Body annotations reposition solids inside a PMI view without touching the master model. They are ideal for exploded assemblies, service manuals, and view-specific storyboards.

Inputs

• annotationID – optional persistent identifier.
• targets – one or more solid selections that will be repositioned.
• transform – translation and rotation applied to the selected solids; edited through the PMI transform gizmo.
• showTraceLine – toggles dashed trace lines from the original location to the displaced position.

Behaviour

• Captures the original placement for every targeted solid and reapplies it automatically when you leave PMI mode.
• Composes successive edits so you can tweak the displacement without accumulating transform drift.
• Draws trace lines that update live as you drag the gizmo, helping viewers understand the exploded direction.
• Shares infrastructure with other PMI annotations, so undo/redo, history, and persistence all work consistently.

Usage Tips

• Create separate Explode Body annotations per PMI view to stage unique assembly moments without impacting the base model.
• Toggle trace lines off for clean presentation shots or on to emphasize motion.
• Pair with leader or note annotations to explain the purpose of each displaced component.
