Gear - Involute Rack

[leyhans]

Hello,
I have used "Gear" to design different types of gearwheels without any problems.
Today I have tried to use "Involute Rack" for the first time and it doesn't function or I don't understand it.
I got only the message "cannot pickle 'Part.Wire' object"

[looooo]

I can't reproduce. Maybe you are using an older version of this addon.

Thanks for your answer. I have tried different times to delete and to install new by Addon-Manger. A friend had the same problem. Today I tried again and it looks OK! Thanks a lot!!
