What is a Work Plane in design terms?

• A. Continuous two dimensional planes that can be used to establish sketch planes. Assembly constraints can also be applied to these.
• B. A three-dimensional solid used for mass modeling.
• C. A projection line used in drafting.
• D. A single curved surface used for shading.

Answer: (A)

A work plane is a flat, two‑dimensional reference surface in a 3D design space that is used to create sketches. Sketches must lie on a plane, so work planes define exactly where and how a sketch is drawn in space. You can create new work planes by offsetting from existing faces or by rotating around edges, which lets you place sketches at angles or from different orientations. Because they serve as reference geometry, work planes are also used to position and constrain components in an assembly. They are not solids, projection lines, or curved shading surfaces, which is why they best describe the concept.
