Project Defintion

Objective

The primary objective of the project is the generation of a 3 - D Wireframe model from a given set of Orthographic Drawings.

Domain

The input and output is done via the AutoCAD package. The input drawings consist of the

• Plan (Top View),
• Elevation (Front View), and
• Left Side View

in the First angle projection. The drawings may consist of straight lines, arcs and circles.

Limitations

• The set of input drawings is restricted in the sense that one can not input Third angle projections, or give the right side view etc.
• The algo does not use the hidden line data and the result may hence turn out ambiguous.
• The input arcs and circles must have their axis parallel to any one of the principal viewing directions.
• The Wireframe generated may be ambiguous, depending on the drawing. A better way of defining what the wireframe represents would be that it is the union of those wireframes whose orthographic projections co-incide with those given as the input.
