Abstract

The purpose of this study is to develop a program that allow the automatic generation of Computer Aided Drawing (CAD) model by implement concept of automation process in CAD software. Automation process has been widely used in industrial field that give positive feedback in terms of its convenience in the drawing process and time saving. An automation be able to help human on completing a job without the excessive work and energy required. Automation process have a high reliability and more accurate in getting the best result in job instead of traditional drawing process and conventional use of CAD software. It also allow human to carries a multiple task in design creation for a shorter time. The program of automation will be develop using the application of Macros tools in CAD software. For this project, the CAD software that has been used to be an example for the case study is Computer Aided Three-dimensional Interactive Application (CATIA) software. The version used is CATIA V5 R21. The system consist of two stage of developing process, which is the first part is the construction process for the CAD model and the second one is the coding development process. The model which for this project is a car rims is first created and recorded in CATIA through the recording tools in Macros without any mistake happened during the modeling process. Then the coding script of the recorded process can be called in the Macros tools to be edited and developed so that the automation process can work with the model. The coding are developed by implying the usage of Visual Basic language in Visual Basic editor in CATIA. The important parameter coding line for creating the basic shape of the model are identified and modified in order to synchronize the model and the input system. For this project, there are four main parameter that has been identified which is rim diameter, rim width, number of rim spoke and number of bolt hole. These parameter is required in the editing process when applying the application of dialogue box in VBA such as the user form. Original parameter is changed into the userform tools so that the input from the userform can be transferred into the model. The final model supposed to have an ability to alter into three different design with different parameter dimension.
