SolidDesigner

A desktop parametric CAD platform focused on history-based solid modeling, extensible workbenches, and a commercial-grade architecture — powered by OpenCascade (OCCT).

What it is SolidDesigner is my long-term product line for building a next-generation CAD platform: History-based modeling with a feature tree and deterministic regeneration Workbenches (Part / Assembly / Sketch / Drawing / Simulation / BIM extensions) with a Ribbon-first UX A clean separation of Model / Representation / Display / Render / UI layers to keep the system scalable If you are looking for a practical, “industrial software” approach to a large CAD codebase (not a toy demo), this is the project. Key capabilities (high level) Parametric feature modeling: sketch → feature creation → edit/redefine → regen Geometry kernel integration: OCCT B-Rep workflows (TopoDS / BRepBuilderAPI / Boolean / fillet, etc.) Professional UI framework: workbench switching, Ribbon, dockable panels, multi-document/MDI layout Document & persistence: container-based document architecture (e.g., .alice), versioning/upgrade pipeline concepts Extensibility: interface-driven modules, plugin-ready runtime services Exact feature coverage evolves quickly — please treat the SolidDesigner repo as the source of truth.

Architecture at a glance

SolidDesigner follows a layered architecture designed for large-scale evolution:

• Core/Foundation: utilities, math/algorithms, plugin/event systems
• Geometry: kernel interfaces + OCCT backend (and future alternatives)
• Data/Model: document, object store, feature definitions, regen services
• Representation/Display/Render: rep graph → display packages → render backends
• UI: Qt/ADS-based docking, Ribbon, workbench lifecycle, command routing

This structure is intentionally similar to how mature CAD systems scale (Creo/NX/SolidWorks-class patterns), while still being pragmatic for an open codebase.

Roadmap direction (public)

• Feature system maturity: stronger schemas, robust redefine, history edits, regen trace
• TopoNaming/selection stability: stable references across feature edits
• Assemblies: constraints/mates, large-assembly performance, lightweight reps
• Drawings: view generation, hidden line removal, dimensions/annotations
• Interoperability: STEP/IGES/STL pipelines (as features stabilize)
• CAE/CAM hooks: mesh/analysis views and manufacturing-oriented workflows
