Perfect arc draw feature in blender (Angle based constraint/ A fundamental feature needed in blender)

Hello guys. This is just a quick update/clarification for my recent feature request/proposal.

To avoid any confusion. This feautre is not similar to blenders curve tool. Although the curve tool has some good utilization to some specific forms, it is still not a viable/useful tool for creating precise arcs/curves that requires consitent angle constraints.

We all know it would be very difficult to achieve the video sample below just by using blender's current curve tool/ the bevel tool. I am aware that there is a powerful tool named PDT in blender but just doesnt have enough control to make the work faster and flexible. But the addon has a lot of potential.

The arc tangent tool can be integrated using the knife tool. Using the knife tool, the user can draw dimensions or curves while at the same time using a curve angle constraint.

I hope we can have some features similar to this in the near future. Thank you blender dev. team.
