OCADml

OCADml is a collection of types and functions built on top of
Gg facilitating Computer Aided
Design (CAD) in OCaml. In particular, the style of design currently supported is
that of 2D drawing and mesh generation via sweeping/extrusion.

Usage

  open OCADml

  let () =
    let fn = 128 in
    let base =
      let sq = Path3.square ~center:true (v2 2. 4.) in
      Path3.(roundover ~fn (Round.flat ~corner:(Round.circ (`Radius 0.5)) sq))
    and c r h = Path3.ztrans h @@ Path3.circle ~fn r in
    let cones = List.map (fun h -> [ c 0.6 h; c 0.5 (h +. 1.) ]) [ 4.; 5.; 6. ] in
    List.flatten ([ base; Path3.ztrans 2. base; c 0.5 3.; c 0.5 4. ] :: cones)
    |> Mesh.skin ~slices:(`Flat 0)
    |> Mesh.to_stl "vacuum_connector.stl"

Documentation

Documentation is available
online, covering the
API. As this library
is not associated with any CAD backend, it is a bit dry on it's own and replete
of examples. To get a better idea of what can be done with the tools provided it
may be helpful to check out a library utilizing them.

CAD Package Specific Frontends

This library only provides a means to generate point and face based geometries,
in order to perform boolean operations and validation of properties such as
manifoldness you'll need to work with a particular CAD package.

Companion PPX

There is a companion ppx, [@@deriving
cad] for generating
transformation functions for user-defined records and abstract types made up of
CAD specific types such as OSCADml's Scad.t,
along with their corresponding vector (V2.t or V3.t) types (and those
composed of them) provided in this library.

Inspiration

This effort began as an extension of the
Scad_ml OpenSCAD DSL, but grew to
the point where it seemed prudent to break out into a "backend" agnostic format
so as to be more generally useful.

Module organization and implementations borrow heavily
from existing libraries in the OpenSCAD community:

• BOSL2

• dotSCAD

• PlotFunction
