a NON-ISOMETRIC LINE is a line that is not parallel to any one of the three legs of the isometric axis. It is not a normal line in a normal multi-view projection of the object.Click to see full answer. Also asked, what are isometric lines?Definition of isometric line. 1 : a line representing changes of pressure or temperature under conditions of constant volume. 2 : a line (such as a contour line) drawn on a map and indicating a true constant value throughout its extent.Additionally, what do you mean by isometric axes and isometric line? Explanation: The angle between the isometric axes is 120 degrees if any line is parallel to it then those are called isometric lines. Auxiliary lines may make any angle with horizontal and oblique is not related here. Then, what is the difference between an isometric line and a non isometric line? In an isometric projection, the plane is placed in such a way that all the, three visible sides of the object make same angle with one another. In the figure, the lines which are parallel to these lines are called isometric lines, and those lines which are not parallel to these lines are called Non-isometric Lines.How are non isometric lines located and sketched?They are measured using the angle from the multiview. They are drawn parallel to the isometric axis. They are located by determining the endpoints of the non-isometric line.
