This example demonstrates how to change a shape of a pattern solid the shell was created from. If you need to change the pattern with Boolean operations, work with constraints or create the shell from different patches, you need to extract the pattern solid into 3D space. After all changes, select patches again and the shell is rebuilt.

Selecting a shell
## 5
After extracting the pattern into 3D, blank the shell or move the pattern away. Otherwise the editing may be difficult – the shell would interfere if you select objects.
## 21
The pattern solid was edited. A box was added and connection between the original solid and the new box was chamfered. The shell will be unblanked.
## 25
The shell is selected again. If the corresponding pattern was extracted into 3D space previously, you have to reselect patches for the changed shell.
## 26
Selection of additional patches

New patches are added to a pattern solid. Changed shell will have different shape.
