If the centers are not located properly, the four individual arcs will not meet to form a smooth, continuous ellipse. When you use this method, be careful that the four centers are located accurately. The four-center ellipse method is presented in figure 43 (on the following page). Very large or odd-sized holes may only be drawn by using the four-center ellipse method. The template is much easier and faster to use, but templates are available only in standard hole sizes. The other method is to use an isometric hole template as a guide. One method is to use instruments and draw the holes by using the four-center ellipse There are two basic methods for drawing holes in isometric drawings.

In this case, the 30° component layout is shown in figure 41 (on the previous page). Where necessary, make supplementary layouts that furnish the linear component values which can transfer to the isometric axis. Using very light lines, lay out the specific details of the object. Using very light lines, lay out a rectangular box whose height, width, and length correspond to the height, width, and length given in the orthographic view (view B). To the best of your ability, make a freehand sketch of the solution (view A). Erase any lines that would be hidden in this object. Connect the corners of the two squares to form an isometric cube. Copy the square back 4.00 units along the left isoplane. Supplementary layouts may be made on any extra available piece of paper and should be saved for reference during the checking of the drawing.įigure 42 (on the following page) is the solution to the problem in figure 40 and was derived by the following procedures: Drawing Problems Using the isometric grid, draw a 4 × 4 square in the right isoplane. If the information is not available, they make a supplementary layout from which the necessary values may be measured. Normally, a draftsman simply measures his full-sized orthographic views and then transfers the information. Figure 41 (on the previous page) illustrates this procedure by showing two angular dimensions that have, been converted to their respective linear values, then showing how these values are transferred to the isometric axis. To transfer an angular dimensional view from an orthographic view to an isometric drawing, convert the angular dimensional value to its component linear value and transfer the component values directly to the axis of the isometric drawing.
