marker modify

If the marker is not visible on the screen, you must type the name.

You may also find it convenient to type the name even if the marker is displayed.

If you created the marker by reading an Adams data set or graphics file, the marker name is the letters MAR followed by the Adams data set marker ID number. For example, the name of Adams MARKER/101 is MAR101. If you created the marker during preprocessing, you will have given it a name at that time.

If a marker is available by default, you may identify it by entering only its name. If it is not, you must enter its full name. To identify a marker under a different part, for instance, you may need to enter the model and part names as well. For example, you may specify marker 'pivot' from model 'links', part 'lower_arm' by entering ".links.lower_arm.pivot". If you type a "?", Adams View will list the markers available by default.

You must separate multiple marker names by commas. If the marker is visible in one of your views, you may identify it by picking on it. You need not separate multiple marker picks by commas.

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 (for example, 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:

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

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.

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.

Adams View applies your location coordinates in the coordinate system you identify with the RELATIVE_TO parameter. The default for the RELATIVE_TO parameter is the default coordinate system.

This parameter can be specified with the node_id parameter during marker modification, to indicate that the marker is NOT to be snapped to the nearest node, but instead its existing location is to be maintained.

for example, marker create marker = .model_1.flex_body_1.marker_1 node_id = 15 location = 10,10,10

marker modify marker = .model_1.flex_body_1.marker_1 node_id = 20 preserve_location = true

The modify marker command will change the node_id of the marker to 20 and its original location (10,10,10) will be maintained.

Depending on the convention you have selected, the rotations may occur about space-fixed or body-fixed axes in any meaningful combination of the x, y, and z axes.

By default, you supply Euler (body313, or body-fixed z, x, z) angles.

You may change this convention with the 'DEFAULTS UNITS ORIENTATION_TYPE=' command. For example, selecting SPACE123 means you will subsequently be supplying space-fixed x, y, and z angles.

Adams View applies your orientation angles starting from the coordinate system you identify with the RELATIVE_TO parameter. The default for the RELATIVE_TO parameter is the default coordinate system.

Note that this does not completely dictate the orientation of the coordinate system. Adams View will position the coordinate system with an arbitrary rotation about the axis. If you must completely control the coordinate system orientation, use ORIENTATION or IN_PLANE_ORIENTATION.

By default, you direct the Z axis of the coordinate system. You may change this convention with the 'DEFAULTS ORIENT_AXIS_AND_PLANE AXIS_AND_PLANE_SETTING=' command. For example, selecting either X_AXIS_XY_PLANE or X_AXIS_XZ_PLANE means you will subsequently be directing the X axis. The plane-convention setting does not affect this parameter.

Adams View applies your location coordinates in the coordinate system you identify with the RELATIVE_TO parameter. The default for the RELATIVE_TO parameter is the default coordinate system.

By default, you direct the Z axis of the coordinate system and locate the ZX plane. You may use the 'DEFAULTS ORIENT_AXIS_AND_PLANE AXIS_AND_PLANE_SETTING=' command to change this convention. For example, selecting X_AXIS_XY_PLANE means you will subsequently be directing the X axis and locating the XY plane.
