Selected Topics in Development of a Cad Application for Sizing Light Gauge Cold Rolled Steel Roof Trusses

Abstract

The goal of the current project is to develop an application which will let users easily define building and truss geometries. Then, optimum truss member sizes will be calculated based on load inputs. The application will be user friendly with required features and is expected to facilitate a wide range of users. The purpose of this document's to discuss the selected topics involved in the development of this CAD application. The selected topics cover the use of an optimization technique to generate the desired roof slopes, the procedure to size the trusses, the data structure required for the computer program, the fonts to display text in 3D, the method to associate constraints on the geometry and the implementation of Undo/Redo functionality in the application.
