IntelliCAD
A modern, native Linux alternative to Autodesk Fusion 360. Direct solid modeling, 2D geometric constraint solving, real ISO metric threads, interactive history timeline, and instant STEP/STL export.
Terminal Installation
.deb package automatically configures desktop launchers and system dependencies for Ubuntu 22.04 / 24.04+ and Debian 12+.
Why IntelliCAD on Linux?
Linux makers and mechanical engineers shouldn't have to suffer through fragile Wine wrappers, web browser lag, or predatory subscription models just to model 3D parts.
IntelliCAD Studio
- ✓ Single-Command .deb Install: Native Debian package installs into your desktop menu in seconds.
- ✓ 100% Native Linux: High-performance Qt6 / PySide6 interface and PyOpenGL viewport.
- ✓ Offline & Private: Instant launch, zero cloud lock-in, zero telemetry tracking your proprietary CAD designs.
- ✓ Fusion 360-Style Workflow: Interactive bottom timeline, shortcut tool search (S), direct surface picking.
- ✓ Standard Engineering Kernels: OpenCASCADE B-Rep solid geometry and SolveSpace 2D constraint solving.
- ✓ Instant 3D Printing Export: Direct STEP and STL export tailored for Bambu Studio, OrcaSlicer, and PrusaSlicer.
Autodesk Fusion 360
- ✗ No Native Linux Support: Requires experimental Wine wrappers that break with every OS update.
- ✗ Mandatory Cloud Lock-in: Project files locked to Autodesk cloud servers; unusable during outages or offline.
- ✗ Restrictions & Fees: Constant feature stripping from hobbyist tiers, document limits, and expensive annual subscriptions.
- ✗ Heavy Background Telemetry: High resource utilization, frequent mandatory client updates, and sluggish loading.
Engineered for Precision & Speed
Every tool in IntelliCAD is designed to get out of your way and let you model with geometric precision.
2D Parametric Sketching
Draw 2-Point Rectangles, Center Rectangles, Circles, 3-Point Arcs, Slots, Regular Polygons, Ellipses, Lines, Fillets, and Parametric Text. Integrated with the SolveSpace geometric constraint solver for ironclad coincidence, tangency, parallelism, and symmetry.
Direct 3D Solid Modeling
Click any planar face directly to Extrude (Join, Cut, Intersect), Revolve, Sweep along guide wires, Loft across profiles, Shell with custom wall thickness, Rib, and Emboss without cumbersome menu diving.
ISO Metric Threaded Holes
Place Simple, Counterbore, or Countersink holes with precision. Supports standard ISO Metric Threads from M3 to M20 with true 3D helical V-groove physical thread modeling ready for 3D printing or tap drill charts.
Parametric History Timeline
Roll back, step forward, reorder operations, or double-click any feature in the bottom timeline to modify dimensions and parameters on the fly. Downstream geometry updates and recalculates automatically.
Interactive Guided Tutorials
4 comprehensive step-by-step interactive tutorials with our breakthrough "✨ Auto-Perform Step (Show Me)" mode that physically demonstrates actions right inside the viewport so you master CAD in minutes.
CAD I/O & 3D Printing Ready
Save and share native .icad design files. Export industry-standard STEP (.step) and BREP (.brep) files for CNC machining, or high-density STL (.stl) meshes ready for Bambu Studio, OrcaSlicer, or Cura.
5 Built-in Engineering Samples
IntelliCAD ships with five production-ready sample parts to inspect, modify, and learn from.
Keyboard & Mouse Controls
Designed for fluid, two-handed muscle memory similar to Fusion 360 and Blender.
| Action / Key | Function |
|---|---|
| Shift + Middle Mouse Drag | Orbit camera smoothly around target point in 3D space |
| Middle Mouse Drag | Pan 3D camera viewport |
| Mouse Wheel Scroll | Zoom camera directly toward cursor focal point |
| S | Open floating Shortcut Tool Search Palette |
| F | Zoom to Fit all active 3D bodies and sketch geometry |
| L / R / C | Quick tools: Line / 2-Point Rectangle / Center Circle |
| D / P | Place Smart Parametric Dimension / Project Edge to Sketch |
| Esc | Exit active tool, cancel pending operation, clear selection |
| Ctrl + Z / Ctrl + Y | Undo / Redo sketch operations and timeline history steps |
