A three-dimensional substrate has a central longitudinal axis extending perpendicular to a central lateral axis. A line taken in a direction parallel to or perpendicular to the central lateral axis of the three-dimensional substrate has a non-apertured, first visually discernible zone in the substrate and a second visually discernible zone in the substrate. The first visually discernable zone has a pattern of three-dimensional features on a first surface or a second surface. At least some of the three-dimensional features define a microzone having a first region and a second region. The first region and the second region have a difference in value for an intensive property. The second visually discernable zone defines apertures. The apertures have an Effective Aperture Area in a range of about 0.3 mm2 to about 15 mm2.
