A nonwoven fabric including continuous filaments forms the nonwoven fabric. The nonwoven fabric having a first surface, a second surface, and a visually discernible zone on the second surface and extending from the first surface. The visually discernible zone has a pattern of three-dimensional features. The first surface is relatively flat. A first plurality of the three-dimensional features have different Z-direction maximum dimensions relative to the first surface. A second plurality of the three-dimensional features have substantially the same Z-direction maximum dimensions relative to the first surface. Each of the three-dimensional features define a microzone comprising a first region and a second region. The first and second regions have a difference in values for an intensive property.
