Description:
Parameter | Value Type | Description |
|---|
circle_name | A New Circle | Specifies the name of the new circle. |
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. |
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. |
radius | Length | Specifies the radius of a circle, an arc, or a cylinder. |
ref_radius_by_marker | An Existing Marker | Specifies the radius of a circle, an arc, or a cylinder to be the distance from the center marker Z axis to this radius marker. |
segment_count | Integer | Specifies the number of straight line segments Adams View uses to draw a circle or an arc. |
Extended Definition:
1. The circle is segmented and therfore can look like a square or triangle if needed.
The circle is defined as a radius drawn around a center marker. The circle's orientation is dependent upon the orientation of its center marker. Its radius is determined by either the 'REF_RADIUS_BY_MARKER' or 'RADIUS=' parameter. The number of sides on the circle is controlled by the 'SEGMENT_COUNT=' parameter. A circle will move with the part its center marker is located on.
2. You may use the name specified by the circle_name parameter later to refer to this circle. Adams View will not allow you to have two circles 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 you use the FILE ADAMS_DATA_SET WRITE command, Adams View writes an Adams data file for your model. Adams requires that each modeling element be identified by a unique integer identifier. If you use this parameter to specify a non-zero identifier, Adams View will use it in the corresponding statement in the Adams data file.
You may also enter zero as an identifier, either explicitly or by default. The next time you write an Adams file, Adams View will replace the zero with a unique, internally-generated identifier. Adams View will permanently store this identifier with the element just as if you had entered it yourself.
Normally, you would let all identifiers default to zero, and Adams View would generate the identifiers for you. You are never required to enter a non-zero identifier. You only need to specify it if, for some reason, you wish to control the Adams file output.
4. 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.
5. 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.
Cautions:
1. Adams View stores the radius value, not the marker name. If you later move the marker specified by the ref_radius_by_marker, the radius will not change.
