The purpose of this paper was to design an automatic system for transform 2D orthographic views to 3D solid objects. The input drawing contains geometric information of lines and circles. The reconstructed objects may be boxes, cylinders and their composites. This system used AutoCAD as a drawing tool. An input 2D orthographic view was created by using this package drawing editor. By using data interchange file (DXF) capabilities the application programs can access AutoCAD database. The script facility was used to execute the set of drawing commands which will create a continuous running display for output. The system was implemented in 7 steps. First, the 2D drawing was created and saved in ASCII code. Then DXF file was created and extracted into drawing commands. The transitional sweep operation was used to reconstruct subparts. The relationships between subparts are utilized to compose the final part. Finally the 3D solid object was displayed.
