Features
A complete design-to-cut workflow in one tool. No switching between programs.
Draw circles, rectangles, polygons, arcs, and lines directly on the canvas. Add text with built-in fonts. No separate CAD program needed.
Import industry-standard DXF and SVG files with automatic path healing — joins broken paths, removes duplicates, and closes gaps.
Upload any image — photo, logo, or drawing — and convert it to cuttable vector paths. Adjust threshold and smoothing for clean results.
Describe what you want — "eagle silhouette wall art" or "welcome sign with SMITH" — and AI generates a plasma-ready SVG design in seconds. 1 free generation per week, with credit packs available.
Inside and outside kerf offsets with one click. Correctly compensates for plasma torch width so your parts come out the right size.
One-click G-code output with configurable lead-ins, pierce delays, feed rates, and THC commands. Preview toolpaths before you cut.
Built-in cut charts for mild steel, stainless, and aluminum. Select your amperage and material type — feed rates and pierce delays set automatically.
Union, subtract, and intersect shapes to create complex designs. Combine simple shapes into intricate cutouts without external CAD tools.
Organize designs with layers. Group and ungroup shapes, lock layers, control visibility — a real design workflow for complex projects.
How It Works
Draw shapes on the canvas, import DXF/SVG files from your favorite CAD program, or trace an image directly into cuttable paths.
Set your material type and thickness, choose kerf compensation (inside/outside), configure lead-ins, pierce delays, and feed rates.
Select your machine controller, generate G-code, and download. Load it into your CNC software and start cutting.
