Issue: 

ZWCAD supports adjusting the pre-selection or selection effect (dashed or highlighted), so how to adjust the setting?

Solution:

There are five related system variables that can be used to set the preselection and selection effect, as shown in the figure below.

A detailed description of each variable is shown below.

Note: Variable PRESELECTIONEFFECT is available for the previous version, but since ZWCAD 2024 this variable is not used anymore and the display effect of preselected objects will always be the Glowing highlighting effect.

The SELECTIONPREVIEW system variable can be set through the Options dialog.
