Fun with CYLINDER
|
|
The staff thought we should celebrate the 100th COW with something
more entertaining and less perplexing, if possible. Having settled on
the CYLINDER statement to make the likeness of a propeller,
it proved to be impossible: the result was perplexing.
As everyone knows, within the Part Maker CREATE command the CYLINDER statement may be used to define a cylindrical shape. You give the coordinates at the end points of the cylinder's axis and the diameter. Tapered cylinders or cones can be made by adding a second diameter. We tried to make the propeller by stretching and fitting and joining cylinders and nothing else. Unfortunately it came out looking more like blender blades. |
|
| So here is something else. We don't want to be like Aaron of old who claimed that he got a gold calf simply by tossing pieces of gold into the fire, so we admit that some design went into the following assemblage of cylinders. |
|
| Here it is at 45 and 90 degrees rotations. |
