Precise drawing.
Native on Windows.

Stratal CAD is a native Windows CAD application for 2D drafting and 3D solid modelling. It is in development and not yet on sale. Everything listed on this page works and is tested in current engineering builds.

From a flat plan to a solid model

Watch this plan rise into solids, then drag the model to turn it.

Stratal CAD · Demo house2D plan

Illustrative model, not a capture of the product. Drag to rotate.

A ground floor plan of a demo house with rooms, doors, furniture, dimensions and a title block, drawn in an early build of Stratal CAD — A demo drawing made in an early build of Stratal CAD. The project is fictional.

Working in early builds

Real geometry.
Tested as it is built.

Stratal CAD runs as a native desktop application with a ribbon and a command line. These capabilities work and are tested in current engineering builds. It is not finished, and more is being added.

Drawing and editing

Lines, circles, arcs, ellipses, polylines, rectangles and polygons, with move, copy, rotate, scale, mirror, offset, trim, extend, fillet, chamfer, stretch and arrays. Grips edit selected objects directly.

Precision

Exact object snaps for endpoints, midpoints, centres, quadrants, intersections, perpendiculars and tangents, with object snap tracking, ortho and polar tracking, a grid and typed coordinates.

Annotation

Text and multiline text, leaders and multileaders, hatching, and linear, aligned, radius, diameter and ordinate dimensions governed by dimension styles.

Layers and properties

Layers with freeze, thaw and plot control, layer filters, linetypes, and per-object colour, linetype, lineweight and transparency.

Blocks and references

Block definitions with a block editor, parametric blocks, external references to other Stratal CAD drawings, and image and PDF underlays.

Layouts and PDF

Model space with multiple layouts, scaled and locked viewports, named page setups, sheet sets and vector PDF export to scale.

3D solids

True solid modelling in a shaded 3D view: boxes and cylinders, union, subtract and intersect, plus extrude, revolve, sweep and loft from sketches.

Parametric sketching

Sketches with geometric and dimensional constraints and a solver, driving extrude and revolve features that are kept in a feature history.

File exchange

Stratal CAD’s own native file format, STEP import and export for solids, and IGES, STL, OBJ and glTF. DXF support is in progress.

Features and availability may change before release.
