Ray, I am with you there! How about a tool that will work similar to the wall tool in architect. we draw our line but can specify the materials, i.e. stone, drain rock, filter fabric, etc...
This would work for almost anything and have the ability to set TOW and BOW elevations. We would also be able to apply textures and images to the wall for graphic representation.
However we would need the ability to set base, caps, geo stabilization and so on. but a better tool for sure would be nice.
