This script allows to create a circle relative to two tangent segments selected in a spline shape.
New : Another version of the script that allows to create a 3-tangents circle has been added.
Enter the radius. The spinner will use the current worldunits.
You have to select only two adjacent segments in an editable_spline or line shape.
It will not work if the segments are in separate splines.
Then, click the button...
-corrected a bug when using a shape with multiple splines.
A new script added : TTT-circle
(also called inscribed circle)
Notice that the segments are not necessarily adjacent.
