Use Testing of an Interactive SystemPart ONE: The Interactive System and Its UsersThis report explores one of the complex computer-aided design (CAS) systems that is widely used in engineering – AutoCAD.Some of the users of this interactive system are engineers, designers, architects, artists, contractors, building managers, graphic designers, prototype designers, product manufacturers, inventors, and drafters (civil, architectural, mechanical, electrical and electronics drafters), among others.The users of AutoCAD must have technical training so as to acquire requisite knowledge and capabilities on how to use the system.

Part ONE Cont.’Capabilities of AutoCAD users include: creating 2D and 3D models of structures and products; dimensioning of drawings; providing measurements and notes of drawings; creating technical blueprints; creating layers of structures or products; importing layers; inserting blocks; importing PAGESETUPS; modifying or editing drawings; using shortcuts; understanding software commands; creating drawings’ viewports; estimating quantity of materials; creative and analytical thinking; effective communication and collaboration; planning skills; ability to save files in different formats; interpreting drawings; and preparing appropriate documentation.These capabilities vary from one user to another depending on their level of training and experience.

Part TWO: The Use CasesThe scope of this report comprises of three use cases:i.Importing layersii.Inserting blocksiii.Quantity estimation.All other uses of AutoCAD were not considered in this report. The focus was only on the three use cases.Users’ capabilities were tested in these three use cases. The main capabilities included understanding of AutoCAD commands, easy identification of the commands, and use of shortcuts.

Part THREE: The Evaluation MethodologyEvaluation ProcedureHuman factors have a significant influence on the ease, efficiency and effectiveness of using interactive systems. This study aimed at identifying the capabilities of AutoCAD users and establish the relationship between human factors and these capabilities.Users in this study were categorized into three groups:i.Beginner usersii.Intermediate usersiii.Advanced users.
