UML is actually a standard that is used in the production of software models. Its function is to facilitate the working of visuals of software artifacts. In order to produce a UML diagram, manufacturer has to gather all the software requirements in a natural like English r semi formal like SBVR language. After that he analyzes and produces the activity diagram manually in an available case tool. One of the main advantages of converting SBVR software requirements automatically into UML is that it minimizes the burden of a system analyst which in turn increases the quality and robustness of a software modeling phase. The paper presents the challenging aspect of transformation from SBVR into UML activity diagram. This method takes the system input requirements specifically in SBVR syntax then parses the whole input specification. It then chooses the UML ingredients like Fact type, Noun, Verb etc and at last generates the visual presentation of selected information. The whole process is fully automated. It is explained through an example.
