The generation of exact drawing from a given sketch is an important step in the manufacturing process. This feature does not exist in any computerized system,so the objective of this work is to add it to a computer-aided design (CAD) package.
The reconstruction of the exact drawing from the sketch will be dependet on the values of the different types of dimensions allocated on the drawing. The suggested system will be added to AutoCAD which will be able to read the sketch drawing file drawn by AutoCAD. The sketch contains both the geometrical elements and dimensions then, by one or more Commands of AutoCAD, the Exact Drawing can be reconstructed.
