It is only an official work around if the feature exists but fails to function in the conventional manner.
In this case, it is a developed function using sticks and stones.
...but no animal were injured in the effort.
Here is an output of many hours of work on this... (click on the image)
Below is the Cartesian curve for the involute...
r=(root diameter/2)
ang=t*90
s=(pi*r*t)/2
xc=r*cos(ang)
yc=r*sin(ang)
x=xc+(s*sin(ang))
y=yc-(s*cos(ang))
z=0
Getting the rotation of the involute in the same location as the dedendum guide is a little bit of a trick but relations will help there.
What I really wonder is if the manufacting module can do this as it is done in the shop. Can you take a hob shape and cylinder and cut this shape with ease, or does it just follow a predefined feature?
