Issue: when selection preview is enabled in CAD/CAM software?, objects are automatically highlighted (thickened and/or dashed) as you pass the cursor over them. This functionality can be helpful to make sure that you are going to select the exact object that you want. But sometime you might want to turn off this effect because there are too much objects in the drawing, and the highlighting effect is excessive.
Solution: here ZWCAD considers this situation and provides a value to turn it off, that it SELECTIONPREVIEW. Input command SELECTIONPREVIEW and set the value as 0.
