Module explode 

Exploded views: placed parts drawn moved off where they are assembled, move by move. Each move (Explosion) is a step’s (explosion), read in the order the steps made them (explosions), and moves the parts it names — and those placed in them — on from wherever the moves before left them (exploded). What the scene draws and a drawing shows of a placed part is where the moves put it; the state, the mates and every other read of a part’s pose stay as assembled.

Structs

Explosion

One move of an explode sequence: the placed parts it moves, by their paths — a part placed in one of them moves with it — and the motion it moves them by, in the frame of the part they are placed in, after every move before it.

Functions

exploded

Where the placed part at path, assembled at world, is after the moves explosions: each that moves it moving it on.

explosion

The move the step step makes.

explosions

Every move the part reader reads is exploded by, in the order the steps made them: an explode sequence, as far as the steps run. Which there are is recorded, so a drawing of them is made again when one changes.
