Parallel Lines Ruler

This ruler was added in version 17.01.06.

This mode will help you draw parallel lines. It has one angle parameter that lets you rotate the line.

You can also change the angle by using the control point while holding down the control key, or by holding space (rotate around current pen position) or shift (rotate around last pen up position).

While holding control, you can also adjust the unit distance between the measure points by sliding the yellow control point.
