Hi Art,

Can't say I understand everything you said ;) , just think you're saying it can't be done... but with a V-bit who's taper angle smaller than the pressure angle it could be done - that's exactly what I was wanting.

  A bit hard to explain. While you can as of next update use a tapered bit ( or a vbit ) in the algorithm, it isnt really shaving an
involute, the angle of the bit will not raelly shave, so long as its lower than pressure angle it may not gouge, but it will make the shape
point by point up the curve. It may work for you, but its not a proper shaving, Im not so sure the result will be pretty. The curvature between segments will not be correct.. since the algorithm is based on graphics, not involution math, I cannt change it to suit that type
of bit properly....

Art,

What do you think about this method:

The "shaving" is achieved by the tool moving radially and not along the X axis.

  That ones a bit of a cheat isnt it? lol..

I see from the videos that definitely allowing tip inwards is a good idea, that one Im looking into doing now,
Ill give some thought on the rest..

a tooth, it could actually have done the job, trouble is it was good only for involutes, no other shape.

I really loved Gearotic 1.0
Pity it couldn't have co existed alongside 2.0 as all many want to do is just involute teeth.
No fancy tickers, let the Lucas Pacemaker take care of those  :D

  It does exist and can run alongside. Check the downloads page, its there for download, just unzip to the gearotic
folder and make an icon for it...
