Built for real drawing work

From the first line to the final layout.

One focused environment for drafting, documentation and solid modeling.

Precise drafting

Draw with intent.

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

Documentation

Layouts that communicate.

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

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.
