Drawing Involute Gears

I use a program called Gearotic 2.0. It can create just about any type of gear you want and will generate .dxf files for placing into other programs or it can directly create the G-code to mill or 3d print your gear. Written by Art Fenerty who wrote the original Mach 3 software. One time nominal licensing fee and you have access to all future upgrades and Art is constantly improving and adding to the program. www.gearotic.com
 
Noob here, but this topic caught my eye.

Many years ago, we were in need of a program to make some involute gears. At the time we only had ACAD2000
After some consultation with a university prof, he wrote up a program that would output an X-Y data file.
The cost was not cheap, but nothing was available "free" at the time.
I had to modify it a little because he hadn't employed a method to ensure that each tooth profile was in the correct angular position.
(his program used a routine that built each profile from where the last one left off.....which introduced accumulated error)
Once that obstacle was out of the way and the program rewritten in Basic, the output was made into a *dxf file that could be used in ACAD.
Worked great
Later on, it was converted over to Visual Basic. I sure learned alot about dealing with radians & programming in Basic/VB.
Now I see there's all kinds of gear generating programs out there.

You can use the free version of eMachineShop to generate gear profiles and save them as dxf files. It is not quite as intuitive as geargenerator.com, but it appears to be a workable solution.

I need to create an 2d AutoCAD drawing of a gear for a project I am working on.
I found a great website that will generate the gear profile - http://geargenerator.com/
but the output is a SVG file. How do I get that into AutoCAD?
I searched the web and found that a program called Inkscape and convert it but it doesn't work. The SVG file has errors.

Does anyone have a different way of creating gear drawings? Lisp routines? Other generators that output DXF?

The gear I want to draw is 108 T 10.16 DP 20 deg PA. The drawing will be used to waterjet cut the gear.

Thanks
Not sure this is what you are looking for, but have you looked in Fusion "ADD-INS", then under "Spur Gear"?
