Applying moment load

[Paolodm]

Hi,
I have read 2 threads about applying moment loads (thread828-145121; thread828-187577), they were very helpful and I understood I have to use the command "total load at point".
But how to choose this point? Are there some rules?
For example, I have the internal lateral surface of a hole, have i to choose the central point of the cylinder?

Thank you.

The point to choose is the point where you want to locate the moment. A moment is always defined in relation to a point. I do not understand what is your problem. Can you describe your problem in more detail ?

You are right, I solved my problem.
I had this doubt while importing loads from mechanism, when you have to associate forces and moments to a surface or an edge. In this case I considered the moment as a total load, and it's not possible because of the necessity of the point of application.
In any case, Thank you very much!
