Is there a way to allow a pattern to extend past the shape?

1. Expand the object (Object > Expand). This will convert the pattern into objects that are masked by the path.
2. Release hte maske (Object > Clipping Mask > Release). This will removethe mask You can now see and delete each pattern tile.
3. Ungroup (Object > Ungroup). I usually do this a couple of times.
4. Use the Lasso tool () to select the tiles you don’t want then delete them. You might have to press the Delete key twice, since some of the objects in the pattern tile won’t be completely selected. Deleting only once will leave parts of the objects behind.

A little complicated, but possible: https://www.vektorgarten.de/align-and-distribute-pathfinder.html
