hi there..

I´m working on a Dungeon Keeper Kit..
FOr the moment, i created my levels out of thousands of block models. That kills the performance..

My new plan is 1 plane model, with 60x60 seperated fields on it.

What I need now:
The plane is created with Wings3D, like this (just with more polygons per field to make walls smoother):


I need a method, to select each vertice around a field, to manipulate it:


Like you see, i want to dig a field into the grid.

Problem now: if i want to build a room into it, i need to select the vertices around the field + the ones between the new field and the last field (so no wall stays between them):



Has someone an idea how to do such a thing?
