How to connect vertices of two grids efficiently? There 2 grid meshes as in image1. They both are relatively distorted.



Now how to connect the vertices from one mesh grid to its partner in the next mesh grid as in image2.


I used "Bridge edge loops" method but for a huge grid it is not easy to employ that method. Is there any other way to do it efficiently.Looking for your valuable suggestions. Thank you
Select boundary loops, which actually will be used anyway afterwards, and proceed with Bridge Edge Loops.


Select all the geometry of both grids.
In 3D View header menu choose Select > Select Boundary Loop (or find it from Space menu).
Once boundary loops selected it's time to connect them. Press Ctrl+E >  Bridge Edge Loops.
