I have some gears from a toy rc-car gearbox, I want to rebuild.
I thought this would be an easy task with the new gear-tool in the powerpack of sharkcad 12.
But I don't get a proper result. The gear, the tool is creating, is way too big...

If I remember rightly the input needs to be in inches. Don't know why but when I tried this out years ago it was the issue then

Hello Kartoffel,
When the gear tool was introduced there was a confusion in units : mm were changed into inches.
It makes everything bigger with factor 25.4.
I thought this had been solved...

Thanks for the hint.
With the module in inches and the radius in mm it works. Stupid!
But in the end, the tooth-shape is totally different, so I will manually design one tooth and then go on with the polar duplicate ...

In the past I used a web site to design gears, it was free and exporting DXF to shark.
I think it was that one :
Gear generator tool

I used this program now: http://forestmoon.com/Software/GearDXF/

But in the end, it is very dissapointing for me, that the "gear-tool" has only basic parameters + the problem with the units...

The unit issues should have been fixed in V14.

How about switching completely to mm?

This problem in this thread is a problem with relative and absolute values.

I have such a problem found i the sheet metal tool of MegaCAD. Wen i load there the imperial Models from Shark, i need in the Sheet Metal tool then values in Inches.

Switch the native system please to Millimeter because i have no possibility to change a 3D-Modal from Imperial in Millimeter. It stay everytime in Imperial, because the programs work with relative values, it doesn't matter until they work with absolute values.

Yeah, I had the same issue using the tool. Pitch was in inch on a metrical Shark.

Another online tool cool to explore may be to add some features in the Shark Gear Tool? https://drivetrainhub.com/gears/
