<p>Standard apparatus for drawing isometric view patterns wherein specific shapes (e.g. a circle) making a number of different inclination angles with a plane (or planes, eg orthogonal planes X, Y, Z) of projection are projected onto that plane of projection and the projections (eg D1...D4) stored in a memory as "standard patterns". Subsequently, at least one standard pattern is called and displayed at an arbitrary position on a screen of a displaying apparatus at a desired magnification. A predetermined shape is drawn as an isometric view by a build-up of such standard patterns. The above-mentioned standard patterns include straight lines and ellipses. …<IMAGE>… </p> |
