oo-method is an object-oriented method for automated code generation. in order to develop a software application by using oo-method, the analyst must subjectively create the diagrams included in oo-method. in this task the analyst must invest too much effort. on the other hand, pre-conceptual schemas are controlled-language-based diagrams for knowledge representation. also, pre-conceptual schemas are previous diagrams to conceptual schemas and they are designed for automatically obtaining uml diagrams. in this paper, we take advantage of pre-conceptual schemas and we propose a set of rules for obtaining oo-method diagrams from these schemas. we also exemplify the proposal with a case study
