Cobalt, at $2,995, is the high-end member of a four-member family of products. The other three Ashlar-Vellum offerings are “Graphite”, “Argon”, and “Xenon”.

• Graphite essentially inherited the feature-set of Ashlar’s flagship product, Vellum. It offers 2D and 3D wireframe drafting and equation-driven parametrics.

• Argon is the most affordable, offering 3D solid modeling (but not history-based), ray tracing, and animation.

• Xenon is a less capable cousin of Cobalt, offering all of the 2D and 3D solid modeling functions of Cobalt as well as ray-trace rendering and animation. However, Xenon lacks Cobalt’s geometric and equation-driven parametrics, “Associative Assembly Tools” and the mechanical parts library, nor does it support dimensioning using geometric dimensioning and tolerancing (GD&T).^[7]
