Custom CAD application development
CoreCAD.NET
Platform architecture & capabilities
Professional 2D drafting, feature-based 3D parametric modeling, scripting & AI automation, with photorealistic rendering planned — a modular set of C# libraries, and the platform every application we build starts from.

The CAD engine for your .NET desktop product.
CoreCAD.NET is a suite of C# libraries that turns the Eyeshot geometry and graphics toolkit into a complete, interactive CAD platform. Every application we build on it gives its users the commands, precision tools, editing, annotation, 3D modeling, automation and output they expect from professional CAD software — under your brand, around your domain logic.
Who it is for
- Software vendorsBuild a vertical CAD or CAD/CAM product — machinery, furniture, steel, plant or signage design — without first building a CAD engine.
- Engineering teamsModernise in-house desktop tools and product configurators with real drafting, modeling and drawing output.
- Technical applicationsEmbed a precise, scriptable CAD view in quoting, planning or production-preparation software.
A layered platform, modular by design.
Every layer is a separate assembly with a clear dependency direction. Start with the 2D core, then add 3D, the ready-made UI, automation, AI or rendering only when your product needs them.
Each layer opens its own page. Scroll sideways to see the whole diagram.

Modular
2D only, 2D + 3D, with or without our UI, automation or AI: you choose, per product.
Optional by discovery
Satellites and rendering are found at runtime; if one is missing, the application keeps working.
Your code is first-class
Your commands, features and data use the same registries, undo, events and file format as the built-in ones.
One platform, seven areas.
Each area has its own page: what it does, how it looks, and the complete list of capabilities.
01 · 2D CAD engine
/corecad/2d/The 2D CAD engine.
Everything a professional drafting application needs, with the interaction style CAD users already know: command prompts, object snaps, grips, typed values and instant undo.
Explore the 2D engine →02 · Drawings & exchange
/corecad/drawings/From model to production drawing.
Paper space turns the live model into dimensioned, scaled sheets with a title block — ready for print or PDF. Standard CAD formats move geometry in and out.
Explore drawings →03 · 3D modeling
/corecad/3d/3D parametric modeling.
Feature-based solid modeling on B-Rep geometry, with a history you can edit, reorder and roll back.
Explore 3D modeling →04 · User interface
/corecad/interface/A complete CAD interface, ready to use.
An optional ribbon application shell wired to every CoreCAD subsystem, with DevExpress skins and English/Italian resources. Use it as it is, or build your own interface directly on the CoreCAD control.
Explore the interface →05 · Automation & AI
/corecad/automation/One command catalog, three front-ends.
Explore automation →06 · Rendering
/corecad/rendering/Photorealistic viewport.
Explore rendering →07 · For developers
/corecad/developers/Familiar .NET code, deep extension points.
Explore extensibility →Build your product, not a CAD engine.
A geometry kernel gives you curves, solids and fast graphics. Users, however, expect a CAD application: commands that guide them, snaps that land exactly, grips, undo that never loses work, dimensions, drawings and file exchange. CoreCAD.NET is that application layer, ready to use.
Starting from a geometry kernel alone
Your team builds — and then maintains — the whole CAD application layer
Starting from CoreCAD.NET
The CAD application layer is there on day one
- Command engine · 200+ interactive commands
- Snaps · tracking · grips · selection filters
- Undo/redo transactions · native file format
- Annotation · constraints · parametric history
- Paper space · printing · PDF · DWG/DXF/STEP
- Ready-made UI · automation · AI connector
- Documented, stable C# API
Illustrative comparison of scope, not of effort in a specific project.
Ship sooner
200+ commands, snaps, grips, dimensions, hatches, blocks and layers work from day one.
Proven foundation
Built on Eyeshot 2025 for geometry, B-Rep solids, graphics and file translators.
Modular
2D only, 2D + 3D, with or without our UI, automation or AI: you choose, per product.
Extensible
Custom commands, parametric features and entity data; public events with veto.
Automation & AI ready
The same command catalog serves C#, sandboxed macros and AI assistants.
Reliable
Every change undoable; recovery after crashes and shutdowns; a scripted release process.
Professional delivery
Signed, protected assemblies; lockstep versions; side-by-side installs.
Developer friendly
IntelliSense on the public API, sample applications and macro examples.
One controlled path for every change.
Whether a user draws with the mouse, drags a grip, runs a macro or an AI assistant issues a command, every modification travels the same route: validation, a single undoable transaction, the document, then notification. That is what keeps large CAD applications consistent.
