Construction of isometric outlines of surfaces using their superimposed orthogonal projections

Abstract

The article solves the geometric task of constructing isometrics of the contour of spatial forms. The problem is solved by special construction of orthogonal projections of especial lines. These lines turn out to be contour lines of intersecting surfaces when they are further transformed into axonometry. Methods are considered to construct isometric contour of curved surfaces with finding their anchor points by superimposing projections of the same name. This simplifies the task of determining the coordinates of anchor points in a complex drawing.
