First Angle Projection

First-angle projection is a method of creating a 2D drawing of a 3D object. It is mainly

used in Europe and Asia. The 3D object is positioned in the first quadrant. Views are

projected onto the planes located behind the part. The projected views are placed on a

drawing.

Third Angle Projection is primarily used in the U.S. & Canada and is based on the ASME

Yl4.3M multi and sectional view drawings standard. Designers should have knowledge

and understanding of both systems.

There are numerous multi-national companies. Example: A part is designed in the U.S.,

manufactured in Japan and destined for a European market.

Third Angle Projection is used in this text. A truncated cone symbol should appear on the

drawing to indicate the Projection system.
