Okay, show of hands,
"How many of us still draw lines arcs and circles on a regular basis?"
"How many of those that still do, plan on doing so three years from now?"
Speaking for me and mine, we draw darned few lines, and I haven't drawn a plain circle in years or an arc in decades, nor do I plan on doing so any time soon. Even back when we did draw 2D lines, arcs, and circles, it was only a fraction of what we drew (that wasn't blocks or parametrically automated), and then we had it customized to control layers at the same time.
I have some questions:
1.) How does this new "feature" help me in the 3D world, using solids, blocks, dynamic blocks, push-pull, etc.?
2.) Where is this feature going in the next five years? How will it grow to meet new releases?
3.) What is the learning curve for power users? What's the ROI?
4.) How customizable is the interface? Will I be able to bend it to how we work?
5.) How well does the interface play with already heavily customized systems?
6.) What's your target market, and just how much do you think that is of the total market?
