Use dotted lines torepresent those lines not in view. AXOMETRIC PROJECTION, CONTINUED 73 AXOMETRIC PROJECTION, Continued Section 21. Since scale, with respect to drawings, is the ratio of projectionlength to real length, it will be seen that the axes in axometric projection may bearranged in place when scales for any two of them are given, by setting up twolines at inclinations to the that will give those scales, and, having arrangedtheir plans correctly, placing the third axis in proper relation to these.
