Struct Form 

pub struct Form {
    pub dialog: Dialog,
    pub layout: Layout,
    pub visuals: Vec<Visual>,
    pub focus: Option<CoordinateSystem>,
    pub sheet: Option<Extent>,
    pub tool: InHand,
    pub selection: Vec<String>,
    pub select_box: bool,
    pub pulls: Vec<Pull>,
    pub prompt: Option<Prompt>,
    pub gizmo: Option<Gizmo>,
    pub hidden: Vec<String>,
}

What an operation shows for a step: the fields of its dialog and what it draws, and what the editor needs to know to edit it the same way as every other step — what is selected, what the operation has in hand, what it drags. Plain data: what a field does when it is set is the operation’s to say when it is sent the Event.

Fields

dialog: Dialog

layout: Layout

Where the dialog is shown: beside the viewport, or as a popup over it (see Layout).

visuals: Vec<Visual>

focus: Option<CoordinateSystem>

A plane to work in, its u/v plane: the viewer faces it head on, stops orbiting, and draws a grid on it. Draggable visuals are dragged in it.

sheet: Option<Extent>

A sheet of its own the step is edited on — a drawing’s paper, laid in focus — and how far it reaches: the viewer shows the step’s visuals alone, without the part, framed to it.

tool: InHand

What the operation has in hand: clicks — and, for a tool that strokes, drags — go to it rather than select.

selection: Vec<String>

The keys of the visuals selected. A click on a selectable visual changes it, and the operation is sent the new selection (Event::Select) to keep.

select_box: bool

Whether a drag from nothing, with nothing in hand, draws a box that selects: the operation is sent it (CanvasEvent::SelectBox) and decides what lies in it, from what its visuals stand for.

pulls: Vec<Pull>

What the step pulls the state towards: the editor solves the program with them.

prompt: Option<Prompt>

A value asked for in place, in the viewport.

gizmo: Option<Gizmo>

A gizmo to move, turn or scale something by: its drags are sent as CanvasEvent::Gizmo.

hidden: Vec<String>

Solids and faces of the part, by name, not to draw while the step is edited: what the step builds, when its visuals show it better — a control cage shown alone.
