 * 1) Press the  button.
 * 2) Create a series of points by clicking in the 3D view. While the command is active, the created points are connected with straight lines, and a construction circle is created centered on each point.
 * 3) Optionally press  before terminating the input to define the degree of the B-Spline.
 * 4) Optionally press  before terminating the input to delete the last created control point.
 * 5) Right-click to terminate the input and generate the curve.
 * 6) Depending on preferences, the tool may remain active to trace a new curve. Right-click again to exit the command.
 * It is possible to define the weight of the control points by changing the radii of the weight circles. The equality constraints on the circles need to be deleted first. The radius constraint is arbitrary, the weight of the control points will be defined by the relative radii of the circles. It works similar to gravity: the bigger a circle is in relation to the others, the more the curve will be attracted to the control point.
 * The visibility of the control polygon, the curvature comb, the degree and the knot multiplicity can be toggled on/off from the B-spline tools toolbar.
 * Check out the other tools in the B-spline tools toolbar for more B-Spline editing tools.
