geometry modify shape shell

Polygons are not necessarily flat. The points and connectivety are read from a file named "FILE_NAME=". The shell is placed at the marker named "REFERENCE_MARKER=". The shell will move with the part that owns the reference marker.

Normally, entity names are composed of alphabetic, numeric, or '_' (underscore) characters, and start with an alphabetic or '_' character. They may be of any length. For more information, see Using Extended Names.

By enclosing the name in double quotes, you may use other printable characters, or start the name with a numeral. If a name contains characters, or starts with a numeral, you must always quote the name when entering it.

Note that you can specify the parentage of an entity (e.g. what part "owns" a marker or a geometry element) when you CREATE it by changing the name. If you enter just the entity name, then the default parent will be assigned by Adams View. If you type in the full name, then you may override the default parent. In most cases, when creating an entity, Adams View will provide a default name. The default name that Adams View provides will specify the parentage that it has assumed.

You may, of course, delete this name and use your own. The form of a full name is:

"...._NAME.GRAND_PARENT_NAME.PARENT_NAME.ENTITY_NAME"

The number of levels used varies from case to case and the parentage must exist before an entity can be assigned to it.

These comments must follow the title statement and be followed by the comment 'END OF MODEL COMMENTS'. This string must be uppercase.

When an Adams Solver data file is written, the comments for an object are written before the statement corresponding to the object.

Shell file format: The first line in a shell file has the form: int int float. The first integer represent how many points are in the shell file. The second integer represents how many polygons are described in the file. The float value represent a scaling factor which is applied to all of the point coordinates.

The lines immediately following the first line consist of the x, y, and z coordinate floating point values for the points. There is one xyz triplet per line. You may use multiple spaces or tabs to separate the x, y, and z values.

Immediately following the coordinate values are the lines for defining the polygon connectivity. The first number on one of these lines is the number of vertices that should be connected to form the polygon.

The following integers are the offsets into the list of points. For example, 4 5 6 2 1 means that the polygon will be formed by 4 points and those points are the 5th, 6th, 2nd, and 1st points in the list of points in the shell file. Note that it is not necessary to explicitly close each polygon by going back to the start point. You may use multiple spaces or tabs to separate the values.
