Sketch Palette, docked at the right while sketching: line type of the selected curves (normal, construction, centerline), Look At, and options kept with each sketch (sketch.options: Sketch Grid, Snap, Slice, Show Profile, Show Points, Show Dimensions, Show Constraints, Show Projected Geometries, 3D Sketch), the degrees of freedom, Finish Sketch. Slice cuts the model at the sketch plane; Snap off places points at the cursor
