[edit] simple summary about section on engineering drawing

I need a very simple summary about section on engineering drawing with some figures

[edit] the symbols for projection

First Angle Projection

Third Angle Projection

These first(or third) angle projection symbols are respectively derived by projecting a (hollow) truncated cone placed in the first (or third) quadrant, in first(or third) angle projection as described by the glass box method and then flattening the vertical projection planes to lie in the horizontal plane.

Due to the symmetry of the cone only one of the side views needs to be generated. The double circles represent the top view of the cone and the trapezoid the side view of the cone.

[TO DO - insert suitable image here showing generation of views.]

[edit] History of Engineering Drawing

I think there needs to be a history section for engineering drawing. Several years ago I read that the invention of drawing that accurately represented the device lead to the "renaissance" more than anything. In the past everything was drawn flat and without Perspective (graphical) and could not be successfully built in most cases. Septagram (talk) 01:36, 4 February 2008 (UTC)

[edit] Example of Eng Drawing

The figure in this section of the article is wrong. The section arrow should point in the opposite direction, and the section A-A note should be below the section view. Iepeulas (talk) 18:14, 5 March 2008 (UTC)
