Desperate need for a internal involute spline gear .dwg/.dxf

[Jodunc]

Any help would be great, I am new to using Gearotic and could really use some help. Needing an internal involute spline .dwg/.dxf for the following;

Number of teeth : 13
Spline Pitch : 8/16
Pressure Angle : 30deg
Base diameter: 1.407
Pitch Diameter: 1.625
Major Diameter: 1.767
Form Diameter: 1.754
Minor Diameter: 1.506/1.510

Hi:

  Open the circular gear tab,

Set pressure angle to 30 degrees.
Set DP to 8
Set pitch shift to .5
Press regen

  A DP 8 shifted by .5 is a DP8/16 spline.

Hope this helps,
