LGS 2D 3.0 This small example demonstrates how to create a G2-smooth tangency between curves using new equal curvature constraint. In order to implement it, you need to create two constraints – tangency constraint and equal curvature constraint and set corresponding help parameters equal. In this example it is done by setting final help parameters for both constraints in the endpoints of the curves. This might also be done by linking corresponding help parameters to the same variable.
