If you look at the 2D analogy, consider a 1″ circle with two, three, an seven equal smaller circles such the circles are tangent to each other and to the larger circle. For 2 circles the diameter of the smaller circle is .5000 and the filled space is .5000. For three circles, the diameter of the smaller circle is .4641 and the filled space is .6402. And for seven circles, the diameter of the smaller circle is .3333 and the filled space is .7778. If the circles were infinitesimally small, the filled space would be .9069.

However, the analogy falls apart when you consider micron sized particles in multi-milllimeter geometries. For all intents and purposes, boundary conditions don’t apply. Furthermore, because the process involved in creating the final geometry creates partial “balls”, there is in effect no boundary.

I love SolidWorks, though. Personally, I use BobCAM for SolidWorks. It is way much easier to use; either free or inexpensive training options are available (webinars, CD’s, tech support); the PathPilot post for BobCAM is free and somewhat easily customizable; and there is no mandatory annual licensing fee.

]]>You are correct – they are part numbers 33441 and 33440. Good catch!

Though the titles are incorrect, there are links in the video that go directly to the pages with those part numbers, if you need the product pages.

Thanks for reading/watching!
