| Isometric Construction of the Bike Frame - page 2 |
 |
Rotate the Bottom Bracket Shell back 120 degrees. Position is centered on the Trace layer ellipse as shown. |
 |
Duplicate the lower rear fork and the original Bottom Bracket Shell ellipse and move off to the side. This fork is separated by 5 inches at the rear, 3 inches at 4 inches from the Bottom Bracket Shell and 1 inch at the shell. Draw plot lines that reflect those dimensions and snap them into place as shown. |
 |
Connect the points for each fork. Convert the front segments to curves and smooth them. Apply a contour with the following settings: Outside, 1 step, and 0.5 inch offset to each line. This will result in cylindrical objects that would be about 7/8 inches in diameter. This works because the Major Axis is 120 percent larger than the Isometric Axis |
