2D CAD kernels when your product needs owned sketch & planar geometry
Custom 2D CAD kernel development — sketch constraints, curves, booleans, nesting, and manufacturing-ready 2D geometry — for engineering software teams and CAD/CAM ISVs worldwide.
Built for: CAD/CAM startups and OEM digital-tool teams, nesting/manufacturing ISVs, and engineering software groups worldwide
Why OEMs commission custom solvers
Many engineering apps win on 2D first: sketches, profiles, tooling layouts, nesting, and shop-floor drawings. ISVs and OEM tool teams often need a 2D kernel they can brand and extend — without paying 3D BREP royalties for planar work.
Hendoi builds custom 2D CAD kernels — curves, regions, constraints, booleans, offsets, and visualization hooks — scoped to manufacturing, design, and CAM product surfaces. We design for clean upgrade paths into 3D when your roadmap needs it.
Companies modernising internal design tools, and ISVs shipping desktop engineering products, get English architecture docs, milestone demos, and IP terms suited to corporate and investor diligence.
Industrial pain points we remove
3D kernel licenses for 2D product workRoyalty terms priced for BREP/NURBS make SME and academy pricing impossible for sketch-first apps.
Constraint solvers that break under real usersOver-constrained sketches and noisy geometry expose gaps commercial wrappers paper over — your brand takes the blame.
Nesting and CAM need robust 2D topologyOffsets, regions, and boolean reliability decide whether shop-floor and nesting products ship.
No path from 2D ownership to 3D laterTeams rent a full 3D stack too early, or build throwaway 2D code that cannot grow into BREP.

Frequently asked questions
Should we start with 2D or jump to 3D?
If your first revenue is sketch, nesting, or planar CAM, start with 2D. Many clients phase 3D BREP after product-market fit — we design that path up front.
Can startups afford a custom 2D kernel?
Yes. We phase delivery: constraints and curves first, then booleans and manufacturing ops. Milestone pricing fits product companies and seed/Series teams worldwide.
Will it integrate with our CAM or nesting stack?
Yes. We treat offsets, regions, and export paths as first-class requirements for manufacturing apps.
Do you also build 3D CAD kernels?
Yes — see our dedicated 3D CAD Kernel Development service when BREP/NURBS ownership is on the roadmap.
