Colliding Line render or Raycasts

Is it possible to only render the part where 2 raycasts (or line renderers) meet?

for examply a raycast on the x-Axis and raycast on the y-Axis. At the point where the 2 raycasts meet you render it (depending on the width of the raycasts)

The concept is to be able to make 3D Models out of 2D Drawings (having supplied a top, side and front view of the drawing).

The 2D Drawings will project raycasts in the x, y and z axises and will render at the points where all 3 raycasts meet thus creating the 3D Projection.
