Measurement Tool - Snapping and Perpendicular

Idea created by dgliddon on Sep 18, 2012
    Perhaps its a bug but snapping doesnt work with the measurement tool until after a first point has been selected.  So it is not possible to start a measurement exactly from an existing feature.  This needs to be corrected.

    A related request is to enable the "constrain to perpendicuar" mode for use with the measurement tool.   This way I can (for example) measure the exact width of a road.   As is I cannot snap the first measurement point to the road edge (previous paragraph) and I cannot constrain the measurement to be perpendicular to the first road edge.
