Which workspace allows the use of 2D sketch geometry to create solid, surface, or T-Spline models?

The Design Workspace is where users can effectively utilize 2D sketch geometry to create solid, surface, or T-Spline models. It provides a comprehensive environment for drafting and modeling, integrating tools that facilitate the transformation of sketches into three-dimensional forms. In this workspace, the design process is streamlined, allowing for the manipulation of 2D sketches to build complex geometric representations.

The other options do not pertain directly to the creation of 3D models from 2D sketches. The Data Panel is primarily used for file management and does not directly facilitate modeling tasks. Degrees of Freedom relates to constraints and how objects move relative to one another, not specifically to model creation. Detail View refers to a method of enlarging or focusing on specific aspects of a drawing rather than the overall design process.
