In Autodesk Inventor, what is the primary function of a Sketch Plane?

The primary function of a Sketch Plane in Autodesk Inventor is to facilitate the creation of 2D profiles. A sketch plane provides the foundation on which 2D sketches are drawn, allowing designers to define the outline and details of a component before it is transformed into a 3D model. By selecting a specific plane, users can create precise geometries, such as lines, circles, and arcs, which can then be utilized for further features like extrusion, revolution, or lofting to develop the complete 3D shape.

Sketch planes are essential in establishing the initial design intent, as they delineate the orientation and location of the sketch in the 3D space. This capability is crucial for developing complex shapes, as it allows the designer to layout features that will become part of the final model. The ability to create accurate 2D profiles is foundational to successful solid modeling in Inventor.
