Comment 1 for bug 171006

I agree with this proposal. It would be great if Inkscape
had this, so called smart guides. I think in AutoCAD this
option is called OSNAP, in Adobe Illustrator is called Smart
Guides, and in Corel Draw they are called Dynamic Guides.
So, something that traces some characteristic points of
objects like CENTER, START, END, INTERSECTION itd.

This feature is really useful when you want to make some
technical sketch, where things have to be precised and only
Snap to Guide and Snap to Grid are usually not enough.
