Objects with Multi-Functional Grips

The following objects have multi-functional grips that offer object-specific and,
in some cases, grip-specific options:

• 2D objects: Lines, polylines, arcs, elliptical arcs, splines, and hatch objects.
• 

  Annotation objects: Dimension objects and multileaders.

• 3D solids: 3D faces, edges, and vertices.

Important Notes

• Grips are not displayed on objects that are on locked layers.
• When you select multiple objects that share coincident grips, you can edit these
  objects using grip modes; however, any object- or grip-specific options are not available.

Tips for Stretching with Grips

• When you select more than one grip on an object to stretch it, the shape of the object
  is kept intact between the selected grips. To select more than one grip, press and
  hold the Shift key, and then select the appropriate grips.
• Grips on text, block references, midpoints of lines, centers of circles, and point
  objects move the object rather than stretching it.
• When a 2D object lies on a plane other than the current UCS, the object is stretched
  on the plane on which it was created, not on the plane of the current UCS.
• If you select a quadrant grip to stretch a circle or ellipse and then specify a distance
  at the Command prompt for the new radius—rather than moving the grip—this distance
  is measured from the center of the circle, not the selected grip.

Limit the Display of Grips to Improve Performance

You can limit the maximum number of objects that display grips. For example, when
a drawing contains hatch objects or polylines with many grips, selecting these objects
can take a long time. The GRIPOBJLIMIT system variable suppresses the display of grips
when the initial selection set includes more than the specified number of objects.
If you add objects to the current selection set, the limit does not apply.
