I have used DataCAD for 26 years and will continue to do so for years to come, however, I would like to see a shift towards inference feedback in future releases. Dynamic snap provides feedback, but, in combination with the need to use the keyboard "N" or scroll wheel to invoke the snap, falls short of simply left mouse click and go. It would be a doppler shift for DataCAD to become an inference based CAD application and IMHO increase productivity exponentially. That's my only wish.
Left-click for Object Snap? What key/button do you then press when you don't want to 'grab' the snap point DataCAD is finding?
Programs that provide inference snapping also provide a hot key to temporarily disable inference snapping when it's not what you want.
I'll leave it to Dave to chime in, but I don't see it being as much a problem programmatically as user-interface-wise.
