I would like the Smartline tool to have an option for a 3-point arc. Currently, the only arc possible is an arc by center. This is a limited option, requiring us to know the center point or radius beforehand. It would be very helpful to be able to place an arc by edge points - start, middle, end. That is a much better choice for a "best fit" arc over existing linework.

The DD Design tool Sketch does exactly this - we have the choice to choose between arc by center or 3-point arc. However, DD tools automatically place constraints, which are unwanted for general drafting, and require an extra step to turn off. DD tools have also been deprecated, and I dread the day Bentley removes them. The best solution is to add 3-point arc functionality to the existing Smartline tool.
