OCCT.NET

A managed .NET port of Open CASCADE Technology (OCCT), the open-source CAD kernel. Work in progress: see docs/design.md for the design and the phase plan, and docs/port-status.md for what has been ported.

  • Pure managed code: no native libraries, no P/Invoke.
  • Faithful: ported class for class from OCCT V8_0_1, keeping OCCT's names, so OCCT's documentation applies.
  • Immutable to callers: every value you get back is immutable; collections are Schematiq.Collections lists.
using Occt;

gp_Trsf aRotation = gp_Trsf.Rotation(gp.OZ(), Math.PI / 2);
gp_Pnt aPoint = new gp_Pnt(1, 0, 0).Transformed(aRotation);   // (0, 1, 0); the original is unchanged

Building

Requirements: the .NET 10 SDK and git.

./tools/get-occt.ps1          # OCCT V8_0_1 source into .deps/occt-src (for the corpus test and port status)
./tools/get-occt-testdata.ps1 # OCCT's test data (99 MB) into .deps/occt-testdata, for the Draw corpus
dotnet test

tests/OcctNet.Oracle.Tests compares the port with native OCCT and needs a sibling build123d.NET checkout with its native build: see docs/oracle-testing.md.

Contributing a port

docs/translation-rules.md says how C++ becomes C#, and docs/porting-playbook.md the steps for a package.

Licence

GNU Lesser General Public License 2.1 with the Open CASCADE exception, as OCCT: see LICENSE, OCCT_LGPL_EXCEPTION.txt and NOTICE. Delabella's port (BRepMesh/delabella.cs) keeps its MIT licence: see THIRD-PARTY-NOTICES.md.
