How to Model a Strandbeest in Revit (Epilogue)

This article is just a brief note. After posting the "final" animations in Part 5 last week, some readers and I noticed something weird in the movement of the legs. So I took another look at the families, and yes, I found something that was not as intended. So I revised the family to comply with the original observations, which is that there should be six pairs of legs, let's say a set of legs "A" and another set "B" on the opposite side. The difference in rotation between a leg A and and its opposite leg B is always -A + 180 degrees. Between one pair and the next there is a difference of 36 degrees, to make the sets of legs take turns to step on the ground, and to maintain the same number of legs on the ground equal to the number of legs on the air.

This is the assignment of parameters for each leg:

Which produces this movement that meets all the goals:

And in the opposite direction, it looks like this:

If you have some music in the background, it's even better.
