If two lines geometrically cross each other but do not logically form an intersection point, is there a way to force the intersection upon them? I figured out a rather cumbersome way for the example in the image:

1. split the horizontal line and remove the middle short section which cross the V line
2. Now the H line becomes two unconnected parts, one at the left of V line, another at the right of H line.
3. Use extend tool to extend the left and right H line to the continuous V line, so now the H line is has left and right parts connected at their intersection with the V line.
4. repeat (1)-(3) for V line.
But is there a single step method to do this?
