How can you create a 2D sketch on a planar face of a 3D model?

To create a 2D sketch on a planar face of a 3D model, selecting the face and using the "New Sketch" tool is the correct approach. This method allows you to directly start a new sketch on the selected planar surface of the model. When you click on the "New Sketch" tool after selecting the face, SolidWorks aligns the sketch plane with that face, providing an ideal starting point for your sketching tasks.

This process is intuitive as it takes advantage of the software's capability to recognize faces on 3D bodies, facilitating a seamless transition from 3D modeling to 2D sketching. By automatically orienting the sketch to the face you've selected, it ensures that the sketch is properly aligned for subsequent operations, such as creating features like extrudes or cuts.

Other methods like using "Sketch on Surface" may not be applicable, especially if there's no specialized feature for that in the context of standard planar faces. Right-clicking the model may provide several context-related options, but the “Create Sketch” command is specifically streamlined for quick sketches initiated from a selected face. Lastly, the idea that you cannot create a sketch on a 3D model’s face is inaccurate; SolidWorks is designed specifically to enable
