Axonometrical projection in geometry call one of ways of display of objects. For creation of an axonometrical projection first of all it is necessary to construct axes, then taking into account distortion coefficients on axes the sizes of the projected subject and its elements are postponed. Having connected the received elements, the axonometrical projection turns out.
Instruction
1. Let there is a problem of creation of an axonometrical projection of some body of rotation. For a start it is necessary to correlate a body to some rectangular system of coordinates, in this case as one of axes for convenience of the account it is necessary to take a rotation body axis.
2. Further the second orthogonal projection of a subject is drawn.
3. Now it is necessary to construct axonometrical axes, it is necessary to have them so that to provide visibility of a bigger surface of a subject, for simplification of construction it is possible to take a coordinate axis of a rectangular isometric projection, in this case distortion coefficients on axes can be considered equal 1.
4. Elements of a figure are projected along axonometrical axes in the ratio 1:1. For descriptive reasons representations of an axonometrical projection, the cut of its next quarter, with the subsequent shading becomes.
