warning message in ads (snap distance)

hi

I'm trying to simulate a patch antenna in ads but always I have this warning:
layout healing changed the layout.the actual highest agregate snap distance...

any ideas?

merci

This message is letting you know that the layout preprocessor has found some gaps in the layout that are smaller than the set/safe threshold. Check the layout to make sure there are no small gaps that are not intended to be there. Under the options > Preprocessor tab in the emSetup view what setting do you have there? You may need to change to a user specified value or turn it off by setting a zero value if necessary.

thanks RealAEL for your help, your answer and the picture........(y)
