Descriptive Geometry.pdf: Master the Techniques of Orthographic, Central, and Parallel Projections

Planes are the most fundamental and most common found in the field of descriptive geometry. A plane is defined as a flat surface that could be represented by three points that are not in a straight line, a straight line and a point not of the line, two intersecting lines, and two parallel lines. The picture plane, or plane of projection, is the surface on which an object is projected, and any plane parallel to either the top or front plane can be used as the picture plane, but for simplicity of construction, the top or front planes will be used as the picture planes.

Plans and elevation some of the primary reasons descriptive geometry comes into play with architecture. Plan and elevation views can also be defined as projections on the horizontal and vertical planes respectively. To construct a building plan, you just create a picture plane in the top view that slices the building just below the roof. Similarly, elevation is an architecture drawing taken in the front view. Other views like section cuts can be also obtained by using a front view that cuts through the building.

Also, re the title of the article: I agree with Taku that, unfortunately, this field does not seem to have a standard name. "Derived noncommutative algebraic geometry" is the best variant I know, and I support this choice 100%, but I'm not sure if that's the standard yet. Some people call it "derived algebraic geometry", which is certainly not a good idea, and if I remember correctly, Orlov sometimes calls this approach just "noncommutative geometry", which maybe is not descriptive enough. When I need to specify the field, I usually say "I study derived categories of coherent sheaves". However, that's not a good title for the article.Dpirozhkov (talk) 03:49, 23 February 2020 (UTC) 2ff7e9595c
