i can't scale patterns in illustrator

thanks for all adobe community members .
i have succeeded to resolve the problem .
but after export the file as png 300 ppi it looks like this when i zoom the picture

Salut!

Je pense qu'il suffit de créer un motif (simple)

et de l'appliquer à un tracé ensuite les options doivent redevenir actives.

Hi

If it still isn’t working, show us two screenshots;

• Your Swatches panel with the Pattern Swatch in it.
• Double-click the Pattern to open Pattern edit mode and take a screen shot of the dialog and the pattern editing.

meganchi is correct; your artwork is not yet a pattern.

• Drag the artwork into the "Swatch" panel to create a pattern
• Fill an object with the pattern fill
• Scale the pattern using Scale dialog or using "~" key method.

Without seeing your art, it is hard to answer. It may be that the site you downloaded the "pattern" from, is not a true pattern, but objects.

You can create one from what you downloaded by selecting the objects and dragging them to your swatches panel.
