CYLINDER Chains III
(Requires GHS Part Maker version 16.34C or later) |
|
Sorry to bring this up again, but John Bonn called to
say he couldn't find a use for CYLINDER Chains. He said
he found it just as easy if not easier to put components
together in the usual way. Also he thought we shouldn't
waste a COW on something as useless as that.
So in order to prove him wrong, we came up with this example of a floating pier with railings on both sides: |

These macros were used to make the stanchions:
macro vector create vector.s cyl 0,beam/2-diam,height+depth, %1*spacing+diam, 0, 0, 0.01, LST // delete vector.s / `One pair of stanchions: macro stanchion .vector %1 create rail.c\p%1 cyl ^,^,^, height,0,-90, diam, LST // / `All stanchions: .stanchion (length/spacing+1,1) 0 In retrospect, we have to admit that John is correct because those stanchions supporting the railing could be made just as well by assigning their locations by ordinary means. Now, if you had a structure where the cylinders or struts or wires (or whatever) go off in directions best specified by angles, and especially if there is branching in the arrangement like a tree, then CYLINDER Chains might prove to be useful. Here's an example: |
