Quick start: The first time SolveSpace runs, you will see an empty workplane.

• To draw a line, choose the Sketch → Line Segment (or circle, or arc, or ...) menu. Then left-click to define the endpoints. Hit Escape if you want to stop drawing before you've formed a closed contour.
• Right-drag to pan, center-drag to rotate, and mousewheel to zoom. To align the view's rotation back to the workplane, choose View → Align View to Workplane.
• To select a line, hover the mouse over the line (it turns yellow), and left-click (it turns red). To dimension the line's length, choose Constrain → Distance / Diameter.
• To move the dimension, drag it. To change the dimension, double-click it, type a number, and hit Enter.
