Production-Ready 2D CAD
Built for Fabrication Shops

A full drafting environment for sheet metal and machined parts — with bend allowances, true-shape nesting, and DXF that lands clean on your laser. Runs in any browser. No installs, no licenses to chase.

The Toolset

Every drafting tool you'd reach for. Nothing you wouldn't.

Phase one ships the complete drafting environment: 12 drawing primitives, 12 modify operations, 13 snap modes, ISO and ASME dimensioning, GD&T, AWS welding symbols, and full layer management. Built so a drafter coming from AutoCAD or DraftSight can start working in under five minutes.

Every primitive a drafter needs — line to NURBS spline. Coordinate input, polar input, dynamic input. Type values while you draw.
Line

Click-to-click, continuous, infinite, ray, with absolute/relative/polar input.

Polyline

Lines + arcs in one entity. Variable width. Switch modes mid-draw.

Rectangle

Corner-corner, center-corner, 3-point. Chamfer/fillet/rotation built in.

Circle

6 modes: center+R, 2-point, 3-point, TTR, TTT, diameter.

Arc

11 construction modes — start-center-end, tangent continuation, chord length, included angle.

Ellipse

Center+axes, axis endpoint, elliptical arc with start/end angles.

Polygon

3 to 1024 sides. Inscribed, circumscribed, edge-defined.

Spline / NURBS

Fit points or control points, degree 2–10, periodic closure.

Point

8 display styles. Divide and Measure place points along entities.

Hatch & Fill

20+ ANSI patterns, gradients, island detection, associative.

Text & MText

Engineering fonts. Stack fractions, ⌀ ° ± symbols, columns, masks.

Blocks

Reusable symbols with attributes, nested blocks, dynamic states.

Sheet Metal

From flat pattern to nested DXF in one tool.

The sheet-metal pipeline most shops cobble together from three programs and a spreadsheet, built natively. Bend tables, K-factor presets, corner relief, true-shape nesting, weight estimates — all generated from the geometry, in real time.

LAYERS

Layer system that scales to a 14-floor structural set.

Visibility, freeze, lock, color, line type, line weight, transparency, plot/no-plot, and per-viewport overrides. Save named layer states to flip between construction, print, and fabrication views in one click.

DXF that lands on the laser without surprises.

Eight DXF versions from R12 to 2018+. Spline-to-polyline conversion at configurable tolerance for CNC compatibility. Layer mapping, font substitution, gap healing, unused-block purge — the things you used to do manually after every export.
