SHELL nged BRL-CAD BRL-CAD User Commands
shells Separates the specified NMG shape into its constituent shells.
`shells` NMG_shape

## DESCRIPTION

Separates the specified NMG shape into its constituent shells. Each shell is written to the database as a separate NMG object with a name of the form shell with a number appended to make the name unique. If the NMG has only one shell, then only one new object will be created. This differs from the `decompose` command in that `decompose` will actually break the object into a number of separate shells if possible.

## EXAMPLES

The example shows the use of the `shells` command to break an NMG shape into its constituent shells.

Break an NMG shape into its constituent shells.

mged> `object.nmg`

Breaks the NMG shape named object.nmg into its constituent shells.
