Cobalt's flexible 3D modeling matches professional power with speed and ease of use in our unique Organic Workflow™ design process. Available for both Macintosh and Windows, Cobalt lets creative people work without worrying about their software. Designers save time and money by moving quickly from conception through completion in the real world of last-minute changes.

Primarily for designers, engineers and inventors, Cobalt leads the Ashlar-Vellum™ product line with on-demand, dimensionally constrained and equation-driven parametrics that make creating variations on a design faster and easier than ever before in 3D design software.

The Vellum® magic is addictive — ask any Ashlar-Vellum customer why they use our products and you'll hear about "Vellumness."
