Struct SectionCut 

pub struct SectionCut {
    pub source: String,
    pub from: String,
    pub to: String,
    pub label: String,
    pub flip: bool,
}

The cutting plane of a section view, as it was PICKED: two anchors of an existing placement’s projection.

The line is stored as two ANCHOR REFERENCES rather than two paper points, for the reason every other sheet reference is: a paper point is not a property of the model, and a placement that moved or a scale that changed would leave the cut somewhere else. Two anchors follow their geometry through a camera, scale, placement or model change — and a section whose anchor is gone goes UNRESOLVED with the reason, exactly as a dimension does, rather than quietly cutting the wrong place.

It is also what makes the cut reachable without a pointer: an anchor has a keyed hit rect (sheet/anchor:<reference>) and a bare paper point does not, so a section picked from free points could not be driven by a script or by anything but a mouse.

Fields

source: String

The placement the line is drawn ON — the view the cut was picked in. Its camera’s viewing direction lies IN the cutting plane, which is what makes the section camera’s frame orthonormal by construction.

from: String

The two anchors the cutting line runs through.

to: String

label: String

The section’s letter — drawn at both arrows on the source view and in this view’s own SECTION A-A caption.

flip: bool

Look the other way along the plane’s normal. The unflipped direction is the drawing convention read off the pick order: 90\u{00B0} clockwise from from \u{2192} to on the source’s paper, which is the side a reader walking from the first arrow to the second has on their right.

Implementations

impl SectionCut

pub const LETTERS: &'static [char]

The letters a sheet hands out, in order, skipping the three a drawing office does not use for a section (I, O and Q read as 1, 0 and O).
