A three-dimensional, nonwoven substrate comprising: a first surface and a second surface; a first side edge and a second side edge connecting a first end edge and a second end edge; a central lateral axis extending between the first end edge and the second end edge; and a central longitudinal extending between the first side edge and the second side edge perpendicular to the central lateral axis; wherein a line taken in a direction parallel or perpendicular to the central lateral axis of the three-dimensional, nonwoven substrate comprises: a non-apertured, first visually discernable zone in the nonwoven substrate; and an apertured second visually discernible zone in the nonwoven substrate; wherein the first visually discernible zone comprises a first pattern of first three-dimensional features on the first surface and/or the second surface, wherein at least some of the first three-dimensional features define a first microzone comprising a first region and a second region, wherein the first region and the second region have a difference in value for at least one intensive property, wherein the at least one intensive property is basis weight, thickness, and/or volumetric density; wherein the second visually discernible zone comprises a second pattern of second three-dimensional features on the first surface and/or the second surface, wherein at least some of the second three-dimensional features define a second microzone comprising a third region and a fourth region, wherein the third region and the fourth region have a difference in value for at least one intensive property, wherein the at least one intensive property is basis weight, thickness, and/or volumetric density, and a pattern of apertures such that the second visually discernable zone has an Effective Open Area in a range of about 3% to about 50%; wherein the first and second three-dimensional features are formed prior to the formation of the apertures and correspond to the shape of a shaped forming belt; and wherein the nonwoven substrate retains greater than 70% of an original caliper after compression at a pressure of 35 kPa.
