You can turn the use of grips on and off and control the size and color of grips under different status.
To change grip settings
Choose Tools > Options.
In the Options dialog box, click the Selction tab.
In the Grip Size,specify the size.
In the Grips, click Enable grips.
Click on the color button separately behind the Unselected grip color, Selected grip color and Hover grip color, to assign colors for grips under different status.
You can use grips to modify objects, such as move, stretch, scale and copy. With the Grips on, the location of grips depending on the type of objects are displayed as follows:
When you perform quadrant grips on circles, the distance is measured from the center point, but not the selected grip. For example, in Stretch mode, you can select a quadrant grip to stretch a circle, and then specify a distance at the prompt of "New circle radius". The distance is measured from the center point, but not the selected quadrant. If you select the center point, the circle moves.
When a 2D solid is not lie on the current UCS, the object is stretched on the plane that the object is created, but not on the plane of the current UCS.
The system variable GRIPOBJLIMIT is used to control the number of grips displayed on the selected object. The value of GRIPOBJLIMIT is not available when you add an object to the current selection set.
