//! CENTERPOINT / MIDPOINT / ONCURVE — constraints between one picked point
|
|
//! and a whole entity selected *before* the tool runs (same "select first,
|
|
//! then invoke" convention `DistanceConstraintCommand`
|
|
//! (`src/modules/draw/constrain/value.rs`) already uses for its own target
|
|
//! entity). The entity side has no ambiguity (a whole circle, or a whole
|
|
//! line whose midpoint/curve is being addressed, not one specific
|
|
//! endpoint) so it doesn't need interactive picking; the point side does
|
|
//! (which of a line's two endpoints, or some other addressable point), so
|
|
//! this command accumulates just that one point pick and hands it back for
|
|
//! the host to resolve via `nearest_parametric_point` — the same split
|
|
//! `CoincidentConstraintCommand` uses and for the same reason (`CadCommand`
|
|
//! has no document access).
