In multiview orthographic projection (see details below), the object surface and the projection plane are parallel, and you can see only two dimensions. This meant that some British companies completely adopted third angle projection. These two planes intersect to partition 3D space into 4 quadrants, which he labeled: These quadrant labels are the same as used in 2D planar geometry, as seen from infinitely far to the "left", taking H and V to be the X-axis and Y-axis, respectively. A rich set of graphics is available. However, the most common views are the six mutually perpendicular views that are produced by six mutually perpendicular planes of projection: The most informative (descriptive) view of the object to be represented is normally chosen as the principal view (front view). Positions of the other views relative to the principal view in the drawing depend on the projection method. Such a view might be desired for calculating clearances or for dimensioning purposes. It is intended to be used in a 2-part series along with Isometric Practice Drawing Two, but could be used as a stand alone assignment.
