Thanks for that. In the test file, do u add the buildWall() method to a branchGroup?

If you don't have money to buy such a program, you may want to download Blender, a fairly decent freeware modeling program. Or you could create a Box object and scale it to an appropriate size. Creating geometry by typing in a lot of datapoints is very painful and I would not recommend it.
