Exact positioning

[BillM]

Monafly:

There is no automatic way to adjust the gear positions.  On the attached files, I started with odd number of toothed gears, module 2, metric.  The first drive gear is 11 tooth.  The  next two gears were meshed to the left and right of the drive gear.  The last spur-3 was added to spur-2.

The "move on gear" function was used alternately on spur-2  and spur-3 that the gears looked like they meshed.

The adjustment didn't take very long and was quite easy to do.  Unless you are doing 100's of these artsy gear designs then you should have the patience to position them manually.  Besides you will be forced to explore some of the features of Gearotics which will be time well spent.

I like John T's method ... build by actual construction rather than simulation.

I imagine that there are combinations of gear sizes that would be physically impossible to arrange.
