Sketcher: New Feature: Symmetric tool
===================================== Creates geometry symmetric to the selected one with respect to the last selected point or line. It does not support the following constraints: - Angle - Horiz/vertical distance - SnellLaw Horizontal and Vertical (directional) dimensions removed from the the copying process when created on a single edge (by picking one edge instead of two points), i.e. Constraint involving only one GeoId at "First".
