Hi, I am in need of an interface that will combine two edges that are tangent continuous and exactly have one point in common. Is there any way to do this? Creating a wire out of them also is not helpful because the shared vertex still remains.

Generally, it will not work. You need a wire with both edges. Edges being collinear at the joint is fine.

The brep bspline structure assumes that an edge has a single smooth curve defined with a single equation or a spline. Two edges can have curves of different type.

Nearly the only rare case it will work is if you know the edges have actually the same curve. This way you just unite the parameter range in one of them and discard the other.

Another (rare) option is when the curves can be approximates nearly exactly with another single curve. So, you could replace the curve in one edge and discard the other again.
