Highlighting

Items in the graphics area are highlighted when you select them, or dynamically highlighted when you move the pointer over them.

You can set the colors for selected items, dynamic highlighting, and other user interface items in Tools > Options > System Options > Colors.

Selected Items

How selected items highlight depends on color settings, the display style you choose, and whether RealView is active.

Selected faces highlight as a luminescent solid color. Selected faces highlight as a solid color. Edges of selected faces highlight as thin solid lines.

Dynamic Highlighting

When you move the pointer over an edge or a face, edges highlight as thick solid lines; edges of faces highlight as thin solid lines. RealView does not affect dynamic shading.

Edges highlight as thick solid lines. Edges of faces highlight as thin solid lines. Edges of faces highlight as solid lines.

In drawings, edges dynamically highlight as thin phantom lines, and edges of faces dynamically highlight as thin dashed lines.

To control dynamic highlighting, click Tools > Options > System Options > Display and select or clear Dynamic highlight from graphics view.

Highlighting

Geometric relations such as endpoints, midpoints, and vertices highlight when the pointer approaches them, then change color when the pointer is poised to select them.

The midpoint highlights and the pointer shows that a coincident relation is possible at its current position. The midpoint has changed color and the pointer shows that it recognizes the midpoint.
