Splined shaft help

[BodyBagger]

Ok, I need to make a splined shaft and I'm not sure what the best method would be. Details as follows:

External Shaft Splines - 6 inches long in the center section of the shaft.
- Shaft will mate to another part with the matching internal spline.
- External spline has a minimum 6.8" pitch diameter.

I tried to use the "Power Transmission" section of the Toolbox to make the external splined section as a 6" long spur gear. I would have then just extruded the shaft from both ends of the spur gear. However, the only specs I have is the 6.8" pitch dia, the root circle has to be 150mm (5.91"), and that the splines need to be about 6" long. If I could just get the splined shaft made, I would use it to "remove" the internal spline from the mating part. Suggestions on the proper way to do this would be appreciated.
Thanks

Help with how to cut the teeth? or modeling the tooth form? or simply help with the missing spline dimensions?

Big missng bit of data is the number of teeth ..........
To a lesser extent ... pressure angle and class/type of fit.

Actually I just finished a few minutes ago a sucessful model using the free trial download of GearTrax from camnetics. It worked great.
