Projection of Planes - 2-1

The document outlines a series of technical drawing exercises involving various geometric shapes, including hexagons, triangles, pentagons, squares, rectangles, and circles. Each exercise specifies the orientation and position of the shapes relative to horizontal and vertical planes, requiring the drawing of projections based on these conditions. The shapes vary in size and orientation, with specific angles and distances from the reference planes provided for accurate representation.

one side is inclined at 45° to the VP.
