how to create a rule which limits pipe length in iLogic?

How would I go about creating a rule in iLogic which would limit the minimum length of a pipe (parameter = Pipe_Length) to be half the outer diameter of the pipe (Pipe_OD), in other words "Pipe_LengthPipe_OD/2"


I know you can use the limits wizard in iLogic,  but is that not only for numerical values as opposed to parameters?


Thanks in Advance for your answers.

I would create create a rule like this:


If Pipe_Length < Pipe_OD / 2 Then
    MessageBox.Show("Pipe length must be no less than half pipe OD!", "Length Warning")
    Pipe_Length = Pipe_OD / 2
End If


I like to use a message box to communicate to the user why a dimension keeps changing back to something. The first argument in the message box is the actual warning, the second is the title of the message box itself.


Then just force the change to your minimum.

Do you use Tube & Pipe?  Because you can create those rule right in the pipe styles dialog.
