- H - vertical length
- A - angle relative to the axis
- D1 - total length
- D2 - total length of second line
- To measure other distance, drag another measuring line, or drag an end of existing one to resize it (animation).
- To measure an angle, crate a protractor by alt-drag ging (drag holding [Alt] key pressed) at an angle from one end of the measuring line.
- To constrain the Measure
