Reference Pages

Docstrings are split up over a few pages:

• Geometry-Level Layout API
• Path API
• Schematic-Driven Design API
• Shape Library

Or jump straight to a particular topic:

Core Geometry

• Units — unit preferences and coordinate types
• Points — Point type and coordinate access
• AbstractGeometry — base geometry interface
• GeometryEntity — basic entities and rendering styles
• GeometryStructure — hierarchical structures and references
• GeometryReference — structure and array references
• Transformations — rotations, reflections, translations, alignment
• Polygons — polygon types, rounding, and boolean clipping
• Shapes — circles, ellipses, and simple shapes (with graphical demonstrations here)
• Coordinate Systems — semantic metadata layers, place!, cells, and GDS I/O
• Texts — text annotations and polytext rendering
• Rendering — render! and curve discretization

Paths and routes

• Paths — path construction, endpoints, directions
• Path Manipulation — straight!, turn!, meander!, bspline!, attach!
• Path Styles — Trace, CPW, Taper, Strands, CompoundStyle, DecoratedStyle
• Routes — automated path construction

Schematic-Driven Layout

• Components — @compdef, @variant, built-in and composite components
• Hooks — PointHook, HandedPointHook, compass directions
• Autofill — automatic pattern fill ("dummy fill")
• Schematics — SchematicGraph, routing, plan, check!, build!
• Technologies — ProcessTechnology and layer configuration
• Targets — ArtworkTarget, SimulationTarget, SolidModelTarget
• PDKs — PDK generation utilities

Solid Models

• SolidModels — 3D geometry, physical groups, postrendering, and meshing
