3D CAD kernels when your product roadmap cannot rent BREP forever
Custom 3D CAD kernel development — BREP, NURBS, topology, booleans, healing, and CAE-ready geometry — for engineering software teams and CAE/CAD ISVs worldwide that need owned 3D IP.
Built for: CAD/CAE startups and OEM digital-tool teams, ISVs, PLM/CAD product companies, and engineering software groups worldwide
Why OEMs commission custom solvers
Geometry is the spine of every CAE and design product. ISVs and OEM tool teams building next-generation CAD, CAM, or solver apps often hit a wall: commercial 3D kernels are expensive, roadmap-constrained, and hard to brand as your own IP.
Hendoi develops custom 3D CAD kernels — topology, BREP, NURBS, booleans, repair, feature hooks, and visualization — scoped to your product surface area. We design for CAE integration so meshing and solvers are not afterthoughts.
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
Kernel licenses that block product pricingPer-seat or royalty terms make your SaaS or desktop pricing impossible for SME and academy markets.
Boolean and topology failures in real modelsCustomer STEP/IGES files expose gaps commercial wrappers paper over — your brand takes the blame.
CAE integration bolted on lateMeshing and solvers need watertight topology and feature history you do not control in a rented kernel.
No owned visualization and selection stackViewport, picking, and display quality decide whether engineers trust a desktop CAD/CAE product.

Frequently asked questions
Build vs license — how do you advise?
We start with a partner checklist: surface area, royalty math, CAE coupling, and time-to-market. Many clients hybridise — license temporarily, build the core they must own.
Can startups afford a custom 3D kernel?
We phase delivery: BREP subset first, then NURBS and advanced ops. Milestone pricing fits product companies and seed/Series teams worldwide.
Will it integrate with our solver stack?
Yes. We design kernels with meshing and solver integration as first-class requirements.
Do you also build 2D CAD kernels?
Yes — see our dedicated 2D CAD Kernel Development service for sketch constraints and planar manufacturing apps.
