Clipping masks
A clipping mask shows artwork only inside a shape — a photo inside a circle, a pattern inside lettering.
Create
- Put the masking shape in front of the artwork.
- Select the shape and the artwork.
- Press Ctrl 7 (Object → Create Clipping Mask).
The frontmost selected shape becomes the mask. Images and text can't be the mask itself — they can be inside one. The mask and its contents become one group, so they move together.
Edit
- Double-click the clip group to work inside it: move the contents within the mask.
- Use Direct Selection (A) to reshape the mask.
Release
Ctrl Alt 7 (Object → Release Clipping Mask) gives you back the separate shapes.
