Built for real drawing work

## From the first line to the final layout.

One focused environment for drafting, documentation and solid modeling.

01

Precise drafting

### Draw with intent.

Lines, polylines, curves, splines, hatches, object snaps, tracking, layers, blocks and external references stay close at hand.

02

Documentation

### Layouts that communicate.

Text, dimensions, leaders, tolerances, tables, paper space, viewports and plot styles turn geometry into deliverables.

03

Open workflow

### Your drawings stay yours.

Work with native files, inspect the source and choose the browser or desktop workflow that fits the job.

Kernel-backed 3D

## Solid modeling, not a visual shortcut.

Build primitives and shape them with extrusion, revolution, sweep, loft and Boolean operations. The geometry kernel resolves the model; the GPU viewport keeps it responsive.

- Orthographic and perspective cameras
- ACIS entity tessellation
- OBJ import and mesh export workflows

Model space Kernel → Tessellation → GPU

One core, two ways to work

## Start instantly. Scale up when you need to.

Web

### Open a drawing in your browser.

No installation. Select a drawing from your device, edit with the shared core and save the result as a local download.

File workflows

## Meet drawings where they are.

Native drawing formats, recovery files, survey data, meshes, plots and property exports fit into a practical project workflow.
