must explode spline to use

mark pigott · 2013-05-24

if you create a trianlge on the screen and close it on creation. The
3 point circle will not work, you have to explode it into 3 separate splines.
In my case I used midpoint snap.
Is there a way it can read the midpoints on a closed triangle spline?

I am trying to get your plugin to work as the TTT circle that Autocad or Draftsight has, and as tangent snap doesn't really work, I used midpoint snap on the triangle.
