Defining tapered endmills

Hi,
Is there a thread on the forum that discusses how to define tapered endmills?
Example: if I'm using a tapered endmill 1/4" shank to 1/8" ballend, do I simply define it as a 1/8" ballend. (In other words always just define the bit in terms of the tip, and forget the taper?)

Personally I always set them up as straight ballnoses as the types of 3D work I do with them only uses the tip.
However you could use the Tapered Ballnose tool type but you'd need to work out the side angle.

I wet through the trouble to draw the tool.
1/8 ball
1/4 shank
Length of taper on mine is 1"
So - I drew a 1/8 ball and a 1/4 shank
I laid out the 1" taper length
I drew a line tangent to ball and to intersection of cut depth.
I drew a line for the center line of the cutter - then trimmed the ball
I trimmed all un-needed lines.
That's the HARD way.
At the time I did that - I was not aware of the easy way.
The easy way is the use the tapered ball nose mill tool in the database.
The angle should be available from the manufacturer.
