Among the different aspects of converting an engineering drawing to CAD, 3-D reconstruction from several views has only been dealt with from a geometric perspective, although a lot of information is of symbolic nature and can be recognized as such directly on a single view. In this paper, we present a first prototype of a system combining geometric reconstruction through the “fleshing out proje...

Deep drawing of two-layer sheet is a suitable way to achieve product with a desired shape and desired properties in sheet metal forming technology. Control of deep drawing parameter such as thinning is the most important challenge in this process. The most difficult part of this challenge is differences in material properties and geometry of each layer. In this paper, numerical approach has bee...

There are mainly two methods of deep drawing analysis; experimental and analytical/numerical. Experimental analysis can be useful in analyzing the process to determine the process parameters that produce a defect free product, and the analytical/numerical modeling can be used to model and analyze the process through all stages of deformation. This approach is less time consuming and more econom...

The rapid change in teaching of engineering drawing using computer aided design (CAD) technology makes a tremendous change on the staff/students in teaching/understanding engineering drawing in technical institutions. Mastering CAD technology has become order of the day for staff/students especially in technical institutions. CAD course have become a compulsory subject in many technical univers...
