Each geometric shape will show different editing options on non-drawing hand panel. It depends on the tool that you initially used for your sketch.
A. Simplify Points: Makes a sketch object smoother by reducing control points.
B. Snap: You can snap control points onto a point of another object.
C. Mirrored: Gives exact mirror of individual models to World mirror plane. Mirrored object is synced to the original parametrically.
A. Low Poly : Visualizes your line alignment of control points. Available if your Curved Surface was created in Precise mode.
B. Loop U: Connects end points of your geometry.
C. Loop V: Loops your Curved Surface in V direction.
A. Directional Arrow : You will see arrows if you are editing a primitive geometry. Pull the arrows to scale the object in both direction.
B. Control point: Extra control points are available if you are editing a Superellipsoid. Move the points to find an interesting shape.
