I have just installed DEX .29 and experimented a little bit with graphics symbols and I discovered that when you have thin layers, shaky hands and waning eyesight that the "right to left" selections rectangle which in my Engineering CAD will "select all crossing" (and enclosed) graphics.
Will attach a picture. The graphics shown was all drawn with lines starting with the default 0.007 and then 'fattened up' to 0.02". Editing before widening the lines was the time where the right to left selection rectangle would have been very handy to pick elements.
The blue line shows selection example, draging right to left over area.
Have been looking for this but not found so far. Have I missed it? if not is this a possibility to have added?
