Natural Language
Tell the AI what you want to build. Design Swiftly's integrated Gemini 2.0 Flash understands your canvas, your shapes, and your intent — then executes instantly.

- ›"Extrude @Wall_1 by 2400mm"
- ›"Add 10mm corner radius to all rectangles"
- ›"Upload photo → convert to SVG cutpath"
From 2D Floor Plan to 3D Space
Select any closed shape, grab an interactive handle, and drag it into a 3D volume — in real time, inside your browser.
Interactive Handles
CAD-standard axis handles (X=Red, Y=Green, Z=Blue) with live unit labels (e.g. 2400mm) always readable during orbit.
Negative Growth
Drag sideways handles through the shape to expand in any direction while keeping the opposite face pinned in world space.
Face vs Shape Select
Single-click selects a face for local editing. Double-click selects the entire 3D object for global manipulation.
3D Face Alignment
Snap any two 3D shapes together by matching Top, Bottom, or Side faces with sub-millimeter accuracy.

A technical walkthrough of the Design Swiftly environment.
Precision Design Canvas
Our custom vector engine delivers sub-micron precision. Draw complex splines, apply path offsets, and resize interactively. The properties panel gives you direct control over every dimension, rotation, and corner radius.
- Dynamic dimension tooltips during resize
- Real-time axis snapping
- Layer-based geometry management
- Multi-canvas tabs with independent undo/redo

Validate Before You Cut
Don't waste expensive material. Our hardware-accelerated 3D simulator shows you exactly how the tool bit moves through your material — including entry angles, lead-ins, and multi-pass depths.
Streamlined Workflow
Switching between 2D design and 3D simulation is seamless. The global command palette (Ctrl+Space) gives instant access to every tool, while the right-side properties panel keeps all parameters within reach.
