Hi all, I'm having a lot of problems trying to manage the materials and constructions databases in ESP-r, which I'm trying is simply create a new database, define new materials with all their properties, but de GUI in ESP-r seems like it can manage that. It looks like some people have create independent GUI for this task, can somebody help me in their GUI?
