I know this might seem like a slightly Niche idea, however, when marking up a drawing using the perimeter tool - converting lines to arcs is slightly time consuming in my opinion. An alternative method of drawing curves would be to create multiple control points forming the curve - once again quite time consuming.
My Idea would be to see if there's a way to allow the perimeter tool to mark-up in a similar fashion to how the highlighter tool marks up when the user holds down left click? I would have thought this would make marking up using this tool much more efficient.
Thanks
