Curve Connect Curves 
The Connect command extends and trims curves to meet at their endpoints.
Commandline options
Specifies whether to join the resulting curves or not.
Extends arcs with an arc segment tangent to the input curve.
Extends arcs with a line segment tangent to the input curve.
Extends a curve (that is not an arc) smoothly or with a straight line.
If the extensions of the picked ends do not intersect, the other ends may be connected.
Type subcrv to select part of a curve as input.
Commandline options  

Join 
Joins the resulting curves. 
ExtendArcsBy 
ArcExtends arcs with an arc segment tangent to the input curve. LineExtends arcs with a line segment tangent to the input curve. 
Type subcrv to select part of a curve as input.

Surface Connect Surfaces 
The ConnectSrf command extends or trims two surfaces to where they intersect.
Pick two surfaces near the edge to extend (blue area), or at the side to keep (red area) if the surface will be trimmed.
Surfaces can be connected when the intersection of their extensions is a curve. It will fail if the intersection is an overlapped region.
