The Importance of CAD in Industrial Biotechnology

• To provide jobs for fresh graduates; space manager or piping designer.

• To design piping systems and equipments related to biotechnology field; bioreactor, autoclave, fermenter, etc.

Structural Drafting

• Structural drafting:

Technical presentation of the structural details in the form of drawing.

• Structural drafting design:

Serve all kind of structural drafting in details together with the structural drawings works.

Structural Drawings

•Assembly Drawing Skeleton assembly drawing showing the relationship of variousparts to be fitted together in the finished structure

• Engineering Design Drawing

Plan view (top view), Elevation view (front view), Bottom section (bottom view) shows overall dimensions, location and size of columns, beams, angles, detail of connections, typical cross sections, various notes.

• Manufacturing (shop or working) Drawing

Detail drawing of all parts of the structure, all dimensions to the nearest 1/16 “, location of all holes for connections, detail of the connection parts, required sizes of all materials
