OneSpace used to be the common prefix for CoCreate product names, such as:

• OneSpace Drafting (2D CAD)
• OneSpace Modeling (3D CAD)
• OneSpace Model Manager
• OneSpace.net (collaboration)

See http://www.cocreate.com for more information.

After CoCreate was acquired by PTC, the naming scheme changed: OneSpace Drafting became CoCreate Drafting, OneSpace Modeling became CoCreate Modeling, and so on.
