Does anyone heard about Gear Tooth tool in Solidworks ? Please see the picture for more clarification. I want to give typical curve on pinion part. And don't know how to do it.
If you can give model view photo or complete drawing I can try the model.
Thanks for the reply. Please find the attached link. There are two files. One is PDF for reference and other is SW part file ( the one I had made with errors). Please review it and let me know.

Can't access that here at work.

How can I attach a file to a forum post? (thanks to Glenn Schroeder)
Here is file
I couldn’t find any issues in your work. Only thing is Sketch11 is under defined. I was told to pattern feature rather than patterning sketch to avoid under defined issue.
Under-defined part is not an issue. I need that gear tool runout cut in the model. Any idea ?
Do you have the straight section completed?
That curved section is an artifact of the revolving cylindrical cutter.
Attach your face file here and end all doubt.

Here is an option -
start with the basic gear, add the "stepped up" diameter, use a swept cut to get the "taper", finish with a circular pattern:
it all depends on how the gear is being made,
It appears you are trying to model the runout of the cutter used to cut the teeth. Todd and others have tried to explain how to achieve that. The radius of that runout is apparently on your drawing, though the value of that dimension is cut off in the image you posted.
As a general rule I do not download files from others so I have not looked at your actual part file, but I have a question regarding your modeling of this pinion. Are you modeling it for a general representation of the pinion or do you need an accurate tooth profile? In many cases a simple representation of the tooth is adequate, just as it is usually preferred to only have a representation of threads and not an actual detailed helical thread feature. If a representation of the teeth is adequate then using a gear profile such as from the Design Library will be an easy way to go. However, be aware that the gear profiles in the Design Library are rather simple representations of gear teeth and far from accurate.
I need accurate tooth profile. And I got same instruction that when gear tool start making gear on this shaft at the end we are leaving some gap (Gear tool runout) so as per the profile of gear tool that round mark will be there. So, that it is easy to understand for workshop guys. I don't know how to give gear tool runout. You can surely download my part and pdf and try if possible for you.
Any help will be a great help.
As Todd Blacksher & others have said a swept cut with the correct tool profile & a path will do what you are looking for.
Use equation-driven curve to develop the involute. Don't substitute with random arcs or splines unless you like crappy performance and warranty claims.
I usually pattern gear teeth by extruding a surface for one side, mirroring surface, making a surface cut, then making revolved pattern. Making the mirror from a surface solves a lot of associativity issues.
Thanks for the reply. Its been great help to me. This is perfect I guess as per your photo. I tried your option but it didn't work for me. See the attached image for model.
Can you please send me this model please. I know I need to learn it at my own, but I'm in a bit hurry for this. If you wish you can send it to my email ID - Hardik_27patel@ymail.com
You need to suppress or delete the revolve & circular pattern first, then adjust the end face of your gear cuts to give room for the runout. These are the settings I used for the swept cut.
I've attached the part but you will need SW2018 to open it.
I cannot see any attachments. Can you please send it to me via mail?
