Difference between ‘Show Visible Labels Only’ and *’*Auto Visible Labels’

These options are applicable only for probed labels and annotated notes. These labels contain two positions, one is label position and the other is attached position in the geometry. Based on these attached positions’ visibility in the current view, labels can be classified as Observable and Non-Observable labels.

• The attached positions of Observable Labels are visible in the view.

• The attached positions of Non-Observable Labels are hidden behind geometry surfaces in the view.

• Users can hide the Non-Observable labels if necessary using the options ‘Show Visible Labels Only’ and ‘Auto Visible Labels’.

• ‘Show Visible Labels Only’ hides the Non-Observable labels for the current view. This is a one time event.

• ‘Auto Visible Labels’ hides Non-Observable Labels and shows Observable Labels dynamically according to the view.

Methods of Arranging Labels

Near: This method repositions all labels and tables very close to the actual label attached positions.

Top-Bottom: This method splits the labels into top and bottom labels and places them based on attached positions.

Compact: This method searches for a possible zone around the label attached position and allocates them without label overlapping.

Circular This method searches for a possible zone around the label attached position and arranges them in a circular manner without overlapping.

Silhouette: This method searches for a possible zone around the label attached position and arranges them along the model outline without overlapping.

Rectangular: This method searches for a possible zone around the label attached position and arranges them in a rectangular manner without overlapping.

Ranking Probe Labels

Probe labels are ranked based on current contour scalar results in descending order by default. Users can reverse the ranking process and make it ascending, i.e., Lowest value will be ranked first. Labels having equal values are given the same rank.

Note: Ranking is applicable only for current derived probe type labels.

• Select probe type as Current Result - Derived type.

• Probe a few values.

• Click Tools | Labels / Notes | Rank Probe Labels.

All labels are ranked and displayed with rank number.

• Click CAE | Probe Settings …

• Uncheck or check the Rank Ascending Order option to reverse the ranking process.

  

Rank numbers will be reversed.
