Sketch inline dimensions while drawing (line length/angle, rectangle width/height, circle diameter, arc radius/sweep, polygon radius/sides, slot length/width): boxes sit on what they measure, typing goes into the first box and locks it, Tab moves on, Enter places the shape, typed values become dimension constraints (expressions and units); Press Pull (Q: faces extrude/cut by sign, edges fillet), X toggles construction on selected curves, Move dialog (M) with preview
