Core Engine Spec v1.0ZylForge CAD & Physics Engine

Parametric B-Rep Geometry Modeler

Direct B-Rep boundary representation geometry engine utilizing true NURBS curves, analytical surfaces, and G2 curvature continuous edge fillets.

Kernel Type

B-Rep / Analytical NURBS Hybrid

File Standard

ISO 10303-242 (AP242 STEP)

Tolerance Limit

1.0e-7 mm Precision

Constraint Engine

2D/3D Variational Solver

The ZylForge Parametric Modeler eliminates boundary representation corruption common in legacy STEP translations. Sketches maintain strict geometric constraint locks across all dimensional edits.

Edge filleting employs G2 curvature continuity, preventing stress concentrations on structural aerospace components designed for high-cycle fatigue environments.

Local model payloads serialize directly into encrypted .zforge SQLite vaults, guaranteeing 100% offline data portability.

Technical Code Example

Production API

// ZylForge B-Rep Constraint API Example
#include <zylforge/geometry/brep.hpp>

int main() {
    zylforge::SolidBody bracket;
    bracket.extrudeSketch("base_sketch", 12.5 /* mm */);
    bracket.applyFillet(G2_CURVATURE, 3.2 /* mm */);
    bracket.validateTopology(); // Enforces zero self-intersection
    return 0;
}
