hide topographic surface perimeter lines

[mary1987]

Hello to all the Revitians! !
are struggling with the division of a topographic surface but the perimeter lines appear in all views, as from image (the tringole).Do you think there's a way to hide it or eliminate it?
Thank you in advance!

I found the solution....
in the view of plant, go the properties, then display options, in the display area model remove the check shows edges... .

Good job
