KingsCAD

3D CAD / Surface Modeling
In active development

A NURBS surface & solid modeling CAD application focused on Class-A surfacing and surface-quality analysis — built for the kind of surface work that Alias, Blender, and MoI3D users expect.

Why KingsCAD

Surface quality you can measure, not just eyeball.

01

Exact NURBS geometry

Powered by the OpenCASCADE 8.0 kernel for exact B-rep and NURBS modeling — not a mesh approximation.

02

Class-A surface QA

Curvature combs, zebra/reflection lines, draft-angle bands, and scan-deviation checking, built into the modeling workflow.

03

STEP / IGES / BRep exchange

Import and export industry-standard CAD formats for a clean handoff to downstream tools.

04

Reversible operation history

Every modeling operation lives in a replayable stack — undo, redo, and scrub the model's timeline.

05

Custom Vulkan viewport

A hand-built Vulkan renderer drives the viewport, with Dear ImGui overlays for in-viewport HUDs.

06

A familiar workflow

A viewport and tool layout inspired by Alias, Blender, and MoI3D, with docked Model Browser, Layers, Tool Shelf, Properties, and History panels.
