I am looking for a list of materials for the field too.I have done the same thing that you did, scoured the list of drawings with no luck. The field drawings also do not indicate inches from feet. I know that much of it is common sense, but still does it take that much longer to add a " or ' so we can be sure? This is very frustrating especially when you are trying to build a robot and the field too.
I know that not many teams are building a team built field, but that list is really needed. If anyone gets a list soon please let me know. I am working on making a list for the materials needed for everything, but the driver's stations and it is taking hours. My construction guy is screaming for the list. When we finish our list, if someone has not already done so, we will publish our list here.
