@tsaspc/node-occ

OpenCascade nodejs extension for solid modeling.

---- NOTICE ------

Module has been slightly refactored for 7.5.0 Updates from OpenCASCADE Library

Current Work:

  • Rework Progress Indicators

  • Add IGES Import/Export

  • Add Surface fitting support

  • Add NURBs support

Long Term goal:

  • Revamp to force XDE

  • Keep Track of Colors

This nodejs extension provides solid construction to nodejs. It provides a simple yet powerful javascript api to construct 3D geometry models.

This project comes with a set of V8 wrappers around OpenCascade API and a sample web application.

quick example

var occ = require("@tsaspc/node-occ").occ;

// construct a box
var box = occ.makeBox([0, 0, 0], [100, 100, 50]);

// construct a cylinder
var cyl = occ.makeCylinder([50, 50, -10], [50, 50, 60], 40);

// cut the box with cylinder
box = occ.cut(box, cyl);

// save result to a STEP file
occ.writeSTEP("somefile.step", box);

node occ

list of features

  • creation of basic shapes ( box, cylinder , cone , torus )
  • boolean operation ( fuse , common , cut )
  • features ( draftAngle)
  • solid properties ( faces, edges, vertices, area , volume )
  • export ( STL GLTF STEP BREP )
  • import ( STEP BREP )

sample web application
