Hi I have created a size rule which first fires a warning message with an option of selecting ok or cancel.

I would like the ok option to then set the model to the min allowable value as specified in my code, however, if the user chooses Cancel that portion of the rule must not run and the size parameter which was changed resulting in the firing of the messagebox should be set back to what it was.

Thanks

If TEDCD - 7 < TECID Then
MessageBox.Show("Endcap and Energy Diffuser Ring DS8 non-conformance. Select OK to automatically reset the Energy Diffuser Ring Ø to the minimum allowable value or CANCEL to go back and select a smaller Endcap ID.", "Energy Diffuser Ring Warning", MessageBoxButtons.OKCancel, MessageBoxIcon.Warning, MessageBoxDefaultButton.Button1)
End If

If TEDCD - 7 < TECID Then 
TEDCD = TECID + 7
End If

Hi wseaston,

You might consider using a Yes/No message to gather an answer from the user, rather than the default OK/Cancel message. If you combine this with a variable to capture the current state of the parameter, before the user changes it, then you can recall that value to use later in the rule if the user choose the No option.

I've provided a sample rule here:

This is just one approach, but I think the use of Yes/No buttons will help you with this rule.

Best of luck to you in all of your iLogic and Inventor pursuits,

Curtis
