LABEL PLACEMENT

Purpose:

Intelligent label placement is used to minimize Label overlap and leader-line crossing. As well as changing label positions the functionality may also change: label orientations, text justifications and alignments, the definition of leader-line shapes and bend-points. The facility uses the SPREAD command, which may arrange Labels locally or remotely.

Instructions:

1. In the Modify menu, click Label placement.

   The system displays the Intelligent Label Placement form.

   

   The intelligent placement operation arranges sets of labels belonging to the same view. The name of the currently selected view is displayed on the form.

2. Operations to define a list of labels:

   • Identify labels by indicating them on drawing.

   • Identify model.

   • Indicate model sub-view and select labels attached to the model.

   • Select region.

   • Indicate region on drawing and select all labels placed within the region.

   • Select all view labels.

   • Add all labels belonging to selected view.

   • Clear selection.

Options:

Placement options tab.

With local positioning, Labels will be positioned around their significant design elements to minimize Label overlap and leader-line crossing. Labels will not be moved from their initial positions unless it is necessary. If they are moved then, as far as possible, leader lines will be straight and at ± 45° to the VIEW axis. The options allow defining offset between labels or diagonal distance parameters.

With remote positioning, labels will be positioned around the VIEW border. It is possible to define a margin outside the VIEW frame that will define the positioning of the Labels. It is also possible to define a side of the VIEW frame alongside of which repositioned Labels will not be placed, and the minimum permissible gap between any two Labels can also be specified.

Labels will be repositioned at the (allowed) VIEW side nearest to their attachment points. Labels along the top and bottom sides will be rotated unless otherwise specified. To avoid overlapping, some leader lines will be doglegged at 45°.

Result:

The arrangement of Labels in the drawing is modified in order to improve the overall presentation and to avoid conflicts with other entities within the drawing.
