On the function of the sweep's tangent tab
Hello everyone
I will write for the first time.
I am not good at English, so I am sorry if there is a strange expression.
In the sweep command, there is a tangent tab, but I did not understand exactly what role it would play for this function.
If there are easy-to-understand illustrations and samples, would you please teach me?
I am sorry to trouble you, but thank you for your consideration.
