Features
Professional Tools, Browser Delivered
A comprehensive CAD toolkit designed for the web — no plugins, no installs, no compromises.
2D Sketch Tools
Everything you need for precise 2D drafting — lines, curves, shapes, text, and hatching with full keyboard shortcut and snap integration.
Lines & Construction Lines
Single lines, continuous chaining, construction lines (xline), and rays. Input via coordinates, polar, or dynamic input.
Polylines
Connected line and arc segments, width control, close with C, undo last segment with U.
Circles (6 Modes)
Center+radius, center+diameter, 2-point, 3-point, tangent-tangent-radius (TTR), and tangent-tangent-tangent (TTT).
Arcs (11 Modes)
3-point, center-start-end, start-center-angle, start-end-radius, tangent continuation, and more.
Rectangles (3 Modes)
Corner-to-corner, center-to-corner, and 3-point rotated rectangle creation.
Regular Polygons
3 to 1024 sides — inscribed in circle, circumscribed about circle, or edge-defined.
Ellipses & Arcs
Center+axis, axis endpoints, and elliptical arcs with full rotation support.
Splines
Fit-point and control-point methods with adjustable degree, closure, and control polygon display.
Text (DTEXT & MTEXT)
Single-line and multi-line text with rich formatting, engineering fonts, special characters, and word wrap.
Hatch & Fill
20+ patterns, solid fills, gradients, auto boundary detection, island handling (normal/outer/ignore), and associative mode.
3D Modeling & Rendering
Convert 2D sketches into 3D solids with a high-performance rendering engine built for the browser.
Extrude
Push 2D profiles into 3D solids with configurable depth. Supports closed shapes, polygons, and splines.
Revolve
Sweep profiles around an axis with adjustable angle for axisymmetric parts like shafts and wheels.
Real-Time 3D Rendering
Smooth, shaded 3D visualization with real-time lighting — right in your browser.
ViewCube & Presets
Fusion 360-style orientation gizmo with clickable faces. Front, Back, Top, Bottom, Right, Left, Iso views.
Precision & Snapping
Achieve exact dimensions and alignments with a comprehensive snap, grid, and input system.
9 Object Snap Types
Endpoint, midpoint, center, quadrant, intersection, extension, perpendicular, tangent, and nearest point snaps.
3 Grid Types
Square, isometric (30/60/90), and polar (radial) grids with adaptive zoom, configurable spacing, rotation, and origin offset.
Dimension Labels
Real-time length, angle, radius, width, and height feedback while drawing and after selection. Editable inline.
Dynamic Input
Type exact values on the canvas — length, angle, coordinates. Tab to switch, Enter to commit. Bypasses grid snap for precision.
Modification Tools
A complete set of entity editing tools with multi-step workflows and command line support.
Transform
Move, copy, rotate, scale, and mirror entities with precise base point and destination input.
Offset
Parallel lines, concentric circles/arcs, expanded rectangles — click the side, type the distance.
Trim & Extend
Trim entities at intersections or extend them to meet boundaries. Auto-detects cutting edges.
Fillet & Chamfer
Rounded fillets (arc) and angled chamfers (line) at line intersections. Supports zero-radius sharp corners.
Arrays
Rectangular (rows/cols/spacing), polar (center/count/angle), and path (along entity) arrays.
Import, Export & Productivity
Seamless file handling and a streamlined workspace designed for productivity.
STL Import & Export
Read and write binary and ASCII STL files for 3D printing, CNC machining, and file exchange.
Light & Dark Themes
Toggle between light and dark modes. Canvas background customizable: default, white, black, gray, or any color.
Keyboard Shortcuts
Full keyboard shortcuts for every tool — L, R, C, A, V, P, E, G, T, H, and more. Work as fast as you think.
Command Line
AutoCAD-style command input: type coordinates, distances, angles, or tool names. Supports absolute, relative, and polar input.
