Module section 

Section views: cut the part, draw what the plane reveals.

A section view is a boolean wearing drawing clothes. The material on the plane’s positive side is removed (through the general cut, against a proxy box sized off the shape’s own bounds, so every downstream guarantee the boolean makes holds here too), and the faces the cut created on the plane become the section outline: the closed loops a draughtsman hatches. The rest of the drawing is the cut solid through the projection machinery, viewed straight down the plane’s normal.

A broken-out section is the same construction with the proxy box shrunk to a window: the cut reveals the interior only where the break is.

Structs

SectionView

A section view: the outline on the cutting plane, and the drawing of what remains behind it.

Functions

broken_section

Cut only within a window of the plane: the broken-out section.

half_section

Cut away one quarter of the part and draw the half-section.

hatch

Hatch the section outline: parallel lines at angle, spacing apart, clipped to the material by the even-odd rule.

section

Cut solid at plane and draw the section.
