Drawing Circular Features
Circular Features
Circular features of an object appear as ellipses on an isometric pictorial.
Step 1) Draw the linear features of the object using the procedure previously described.
Step 2) Draw a box whose diagonals meet at the center of the circle and the length of the sides are equal to the circle’s diameter.
Step 3) Draw an ellipse in the box whose major axis is aligned with the long diagonal of the box. The ellipses touch the box at the midpoint of its sides.
The same procedure is used for creating radii except that the unwanted part of the ellipse is erased or trimmed.
