LABEL GEOMETRY Attribute [Part_name [Colour]]

                                                          

FEMGEN Command only.

The command LABEL GEOMETRY allows the user to specify the geometrical attributes that will be labelled, the part name to which the labels will be applied, and the colour to be used for the labels. The command word ALL may be used instead of a part name if labels on all parts are required and the command word CURRENT if labels on all currently displayed parts are required (this is the default).

Once the attribute to be displayed has been selected the part to be labelled can also be `picked' from the screen.

Return Level: LABEL GEOMETRY except for OFF

Notes:

1.

Use of colour
When displaying geometry labels, the use of either WHITE, RED, ORANGE, YELLOW, GREEN, BLUE or VIOLET colour may be specified.

2.

Labelling of Materials, Physical Properties and Coordinate Systems
These will only be labelled if they have been assigned to a part.

3.

Labelling of Loads and initial conditions
When requesting that a load be labelled it is possible to specify the load name or the load number instead of a part name and this will label that load name on all parts to which it has been assigned. To obtain a graphical representation of a load the command LABEL MESH LOADS must be used.

4.

Labelling element types
If the User has selected an analysis environment (with PROPERTY FE ... or by the use of an environment variable) then the element type specific to the FE package will be displayed on the relevant geometry. Otherwise the FEMGEN generic element type will be shown.

5.

Labelling of local axes
When requesting that the local axes for a part be displayed it is possible to specify that either ALL axes or only the X, Y or Z axis be shown. If the local axes for a part are changed, then it will be necessary to use LABEL GEOMETRY AXES to recalculate the orientation vectors, rather than using DRAWING DISPLAY.

6.

Display of surface normals
The positive direction of the local Z-axis of a surface (surface normal) is indicated by a single arrow drawn from the centre of the surface. The arrow is red if it is pointing away from the screen (viewer) and green if it is pointing towards the screen. Only surfaces will have their normals displayed. Note that to reverse the direction of the local Z-axis of a surface the GEOMETRY FLIP command can be used.

Examples:

1.

LABEL GEOMETRY BODIES WING RED

Labels the bodies for the part named `wing' using colour red.

2.

LABEL GEOMETRY DIVISIONS

Labels the lines with the division numbers that have been assigned to them as meshing controls.

3.

LABEL GEOMETRY LOADS CAS8 BLUE

Labels all parts, using colour BLUE, that have the Load Instance (name) CAS8 applied to them.

4.

LABEL GEOMETRY NORMALS ALL

Displays the surface normals for all the surfaces in the model regardless of whether a surface is currently displayed or not. The arrows representing the surface normals will be coloured red if they are pointing away from the screen and green if they are pointing towards the screen.

5.

LABEL GEOMETRY AXES L12 X YELLOW

Displays the local x-axis of line L12 in yellow.
