Is there any way to generate an involute spline in NX?

Is there any way to generate an involute spline in NX?

Is there any way to generate an involute spline in NX?

(OP)
As per the title, is there an easy way to generate an involute (ANSI) spline for NX? I have played around with the gear grip code and I am not getting very food results for 45 degree splines. I have also tried the MITCalc spline program but it doesn't give the option for changing the spline type (fillet root vs flat root etc) and even then the results are less than ideal.

Surely there must be something that creates a decent dxf file? Splines aren't that uncommon...

One way to do it is with law curves. If you search this site for involute law curve, I'm sure you will find something useful.

I was kinda hoping I wouldn't have to construct something from first principles. I was looking for something I can input teeth number, pitch, pressure angle and boom, a spline.

RE: Is there any way to generate an involute spline in NX?

I forgot about the reuse library examples; in the library there is an example of an involute law curve.

If you have a license that allows you to run the "china toolkit", you can run an add-on gear generator (or so I've heard, I don't have the license).

An old GRIP program exists that generates gears.

Alas, there is no gear tooth generator supplied with the base NX modeling license.

I mentioned I played around with the GRIP code, it doesn't produce anything usable for 45 degree pressure angles.

Tried the China toolkit but I don't have the license.

It's probably not 64-bit.

John,
You are right, because that DLL runs flawlessly on NX 7.5 32bit.
