This task shows you how to connect two elements of the curve type,
using a connecting curve (a spline) that goes through their end points.
A connecting curve is associative, and it can be continuous in point, in curvature or in tangency with its support curves. You can define the tension value and the direction of the continuity at each connecting point, as well as add constraints to the connecting curve. Moving a connecting curve will change the shape of the support curves accordingly. |

Open the Connect_Curves.CATPart document. | |||

Tension value corresponds to a multiplying coefficient applied to the tangent vector norm (available with Continuity in tangency and Continuity in curvature options only). The default value is 1 and the 0 value corresponds to a continuity in point.

Locations where you click to select the first and the second element are important: the closest point to where you click will be automatically used as the starting point and the end point of the connecting curve. Always click close to the point you want to connect, or click the point itself. |

A connecting spline appears: it is continuous in curvature to both selected elements. |
