How to control an exact radius when using Artisan Organic Toolset

Hi! How do you control an exact radius when using Artisan Organic Toolset?


When I want to make a hole in face with an exact radius how do I do it with that plugin?
And when trying to round an edge I draw 2 lines on face to indicate the tool my needed radius but subdividing the mesh finally doesn’t match the radius too, as you see.
