Custom CAD Software Development Services for 2D and 3D engineering products
Custom 2D and 3D CAD software development for OEMs and ISVs — desktop modeling applications, geometry kernels, viewers, sketch systems, B-Rep/NURBS workflows, and engineering CAD products you own.
Built for: Aerospace and automotive OEMs, manufacturing software companies, CAD/CAM ISVs, and industrial product teams in the US, Europe, Canada, Australia, Japan, and the Middle East
Why enterprises commission custom CAD software
Custom CAD software development becomes strategic when off-the-shelf modeling tools cannot encode your geometry standards, manufacturing constraints, review gates, or product differentiation. Aerospace, automotive, and industrial teams often need a branded 2D or 3D CAD application — not another seat of a general-purpose suite — with workflows, file formats, and performance tuned to their programs.
Hendoi builds end-to-end custom CAD products: sketch and constraint systems for 2D, B-Rep/NURBS modeling for 3D, desktop UI, selection and visualization, import/export (STEP, IGES, and related formats), automation, and integration with PLM, CAM, and CAE. We treat geometry correctness, undo/redo, large-assembly performance, and release ownership as first-class requirements from day one.
Companies choose custom CAD when they need IP ownership, teachable or OEM-branded tools, specialized feature trees, or tightly coupled analysis handoff. Plugins alone are not enough when the core modeling experience must be yours. Our engagements cover architecture, prototype, core implementation, validation on your sample models, documentation, and long-term maintenance options.
Whether you are launching a new CAD ISV product or replacing fragile internal tools for a global engineering organization, we structure milestones around demonstrable modeling behavior, English technical documentation, and procurement-ready IP terms for stakeholders across North America, Europe, Asia-Pacific, and the Middle East.
Industrial pain points we remove
Generic CAD cannot encode your processFeature trees, drawing standards, and manufacturing conventions unique to your programs do not fit commercial defaults without endless workarounds.
2D and 3D ownership are split awkwardlyTeams rent a full 3D stack for sketch-led work, or ship throwaway 2D tools that cannot grow into B-Rep/NURBS later.
Plugins hit a ceilingWhen the host CAD product, license model, or UI cannot carry your brand and roadmap, extensions alone stop being enough.
Performance fails on real assembliesLarge models, dense drawings, and concurrent users expose architecture gaps that demos on small samples never show.
IP and support are unclearEnterprise buyers need explicit source ownership, dependency licensing, update paths, and handover — not a black-box customization.

Why choose Hendoi
Engineering-first CAD product delivery
We start from geometry behavior, review evidence, and manufacturing handoff — not from a generic UI template.
2D and 3D under one roadmap
Sketch-first products can grow into 3D without a rewrite when architecture and kernel strategy are set early.
High-performance native applications
Desktop CAD is built for real assemblies, selection performance, and sustained engineering use on Windows and Linux.
Aerospace and industrial domain expertise
Airframe, tooling, and manufacturing constraints inform modeling UX, exchange quality, and acceptance tests.
Long-term maintenance options
Release engineering, regression fixtures, and support models keep the product viable after the first launch.
IP ownership clarity
Source, third-party licenses, and build instructions are scoped for corporate and investor diligence.
Enterprise-quality architecture
Module boundaries, APIs, diagnostics, and deployment paths are designed for multi-team ownership worldwide.

Frequently asked questions
Do you build both 2D and 3D custom CAD software?
Yes. We deliver sketch- and drawing-centric 2D products, full 3D modeling applications, or a phased 2D-to-3D roadmap under one architecture.
How is this different from CAD plugin development?
Plugins extend a host CAD system. Custom CAD software is your product — modeling core, UI, file formats, branding, and release ownership.
Can you use Parasolid or another commercial kernel?
Yes. We can integrate commercial kernels, build custom kernel layers, or hybridize — see also our Parasolid Integration and 2D/3D CAD Kernel services.
Do you support STEP and IGES?
Yes. Production import/export, healing, and validation are commonly in scope for manufacturing and supplier exchange.
How long does custom CAD software development take?
Typical programs phase a vertical slice in months, then expand features. Duration depends on 2D vs 3D scope, kernel choice, and acceptance rigor.
Can you integrate with PLM, CAM, or CAE?
Yes. We design APIs, file handoffs, and metadata contracts for PLM, CAM, mesh/CFD/FEA, and enterprise identity early.
Do you support Windows and Linux?
Yes. Native desktop targets are scoped per product; many enterprise CAD products start on Windows and expand as needed.
Can you sign an NDA?
Yes. We routinely work under NDA for OEM and ISV geometry IP, samples, and roadmaps.
Who owns the source code?
IP and source-ownership terms are written explicitly for enterprise procurement and long-term product strategy.
Do you provide maintenance after launch?
Yes. Optional maintenance covers releases, performance tuning, format updates, and feature roadmap delivery.
Can startups afford a full custom CAD product?
We phase delivery: core modeling and exchange first, then automation and advanced features — milestone pricing fits product companies.
Will the CAD software work with large assemblies?
Large-assembly performance is treated as an acceptance requirement with budgets for load time, selection, and memory.
Do you also build CAD viewers only?
Yes — when review-only tools are enough, see our CAD Viewer Development service; many programs combine viewer + modeling later.
Can you modernize a legacy internal CAD tool?
Yes. We stabilize known-good behavior with fixtures, then replace high-risk seams progressively without freezing production work.
Need custom 2D or 3D CAD software you own?
Share your sample models, 2D/3D scope, target users, and file-format requirements. Hendoi returns a phased custom CAD architecture and delivery plan for teams across the US, Europe, Canada, Australia, Japan, and the Middle East.
