Description:
Parameter | Value Type | Description |
|---|
extrusion_name | A New Extrusion | Specifies the name of the new extrusion. |
adams_id | Adams_id | Specifies an integer used to identify this element in the Adams data file. |
comments | String | Specifies comments for the object being created or modified. |
reference_marker | An Existing Marker | Specifies the marker used to place and orient an extrusion. |
profile_curve | An Existing Gwire | Specifies the object used to define the profile of the extrusion. |
points_for_profile | Location | Specifies the points used to define the profile of the extrusion. The points are relative to the extrusion's reference marker. |
path_curve | An Existing Gwire | Specifies the object used to define the path of the extrusion. |
path_points | Location | Specifies the points used to define the path of the extrusion. |
length_along_z_axis | Length | Specifies the legth along the Z axis of the reference marker to extrude the profile curve of the extrusion. |
relative_to | An Existing Model, Part Or Marker | Specifies the coordinate system that location coordinates are with respect to. |
analytical | Boolean | |
Extended Definition:
1. An extrusion is defined by a path polyline curve and a profile curve, which may be either a polyline or a data element curve. The profile curve is in the X-Y plane of its parent part. Z coordinate values of the profile curve are ignored. The path curve is a polyline that describes how the profile will be swept along. The extrusion is placed with respect to the marker named 'REFERENCE_MARKER=' using the same orientation that the path curve has with respect to its parent part. The extrusion will move with the part which owns the reference marker.
2. You may use the name specified by the extrusion_name parameter, later to refer to this extrusion. Adams View will not allow you to have two extrusions 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. You may specify an arc, circle, spline curve, polyline, or outline for the path_curve parameter. The object defines the path along which the profile curve will be swept.
5. The points specified by the path_points parameter are relative to the extrusion's reference marker. The points defines the path along which the profile curve will be swept.
6. If the relative_to parameter is not specified, the default coordinate system is used. The default coordinate system is initially your model, i.e. the global coordinate system. You may change the default coordinate system using the 'defaults coordinate_system' command.
Tips:
1. You may specify an arc, circle, spline curve, polyline, or outline for the profile_curve parameter The object should be in the X-Y plane of the extrusions reference marker.
