geometry create shape ellipsoid
Allows for creation of the ellipsoid object.
Format:
geometry create shape ellipsoid |
|---|
ellipsoid_name = | a new ellipsoid |
comments = | string |
center_marker = | an existing marker |
x_scale_factor = | length |
y_scale_factor = | length |
z_scale_factor = | length |
Example:
geometry create shape ellipsoid & |

ellipsoid_name = | ELLIPSOID__1 & |
center_marker = | MARKER_74 & |
x_scale_factor = | 2 |
Description:
Parameter | Value Type | Description |
|---|
ellipsoid_name | A New Ellipsoid | Specifies the name of the new ellipsoid |
comments | String | Specifies comments for the object being created or modified. |
center_marker | An Existing Marker | Specifies the marker at the center of a circle, an arc, the bottom of a cylinder, or the bottom of a frustum |
x_scale_factor | Length | The X_SCALE_FACTOR parameter is used to specify the scaling of the initial unit sphere along the center marker's x axis. |
y_scale_factor | Length | The Y_SCALE_FACTOR parameter is used to specify the scaling of the initial unit sphere along the center marker's y axis. |
z_scale_factor | Length | The Z_SCALE_FACTOR parameter is used to specify the scaling of the initial unit sphere along the center marker's z axis. |
Extended Definition:
1. An ellipsoid is a unit sphere that has been scaled in the x, y, and z directions. The ellipsoid is placed at the marker named 'CENTER_MARKER='. The X_SCALE_FACTOR, Y_SCALE_FACTOR, and Z_SCALE_FACTOR parameters are used to specify the scaling of the initial unit sphere along the center marker's x, y, z axes. The ellipsoid will move with the part which owns the center marker.
2. Specifies the name of the new ellipsoid. You may use this name later to refer to this ellipsoid. Adams View will not allow you to have two ellipsoids with the same full name, so you must provide a unique name.
Normally, entity names are composed of alphabetic, numeric, or '_' (underscore) characters, and start with an alphabetic or '_' character. They may be 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 over ride 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, or 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.
3. When an Adams Solver data file (.adm) is read into Adams View, all comments associated with a statement (from the end of the previous statement through the end of the current statement) are stored with the object. Comments in the data file can be associated with model.
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.
4. Specifies the marker at the center of a circle, an arc, the bottom of a cylinder, or the bottom of a frustum. If you are creating a circle or an arc, orient the center marker so that its z-axis is normal to the plane of the circle or to the plane of the arc. Similarly, if you are defining a cylinder or a frustum, orient the center marker so that its z-axis is normal to the bottom of the cylinder or the frustum.
