You can rotate objects
in your drawing around a specified base point.
To
determine the angle of rotation, you can enter an angle value, drag
using the cursor, or specify a reference angle to align to an absolute
angle.
Rotate an Object by a Specified
Angle
Enter
a rotation angle value from 0 to 360 degrees. You can also enter
values in radians, grads, or surveyor bearings. Entering a positive
angle value rotates the objects counterclockwise or clockwise, depending
on the Direction Control setting in the Drawing Units dialog box.
Rotate an Object by Dragging
Drag the object around the base point and specify
a second point. Use Ortho mode, polar tracking, or object snaps
for greater precision.
For example, you can rotate the plan view of
a house by selecting the objects (1), specifying a base point (2),
and specifying an angle of rotation by dragging to another point
(3).
Rotate an Object to an
Absolute Angle
With the Reference option, you can rotate an
object to align it to an absolute angle.
For example, to rotate the part in the illustration
so the diagonal edge rotates to 90 degrees, you select the objects
to be rotated (1, 2), specify the base point (3), and enter the
Reference option. For the reference angle, specify the two endpoints
of the diagonal line (4, 5). For the new angle, enter 90.
Rotate
an Object in 3D
To rotate 3D objects, you can use either ROTATE
or ROTATE3D.
- With ROTATE, you can
rotate objects around a specified base point. The axis of rotation
passes through the base point and is parallel to the Z axis of
the current UCS.
- With ROTATE3D, you
can specify the axis of rotation using either two points; an object;
the X, Y, or Z axis;
or the Z direction of the current view.
To rotate an object
- Select the object to rotate.
- Specify the base point for the rotation.
- Do one of the following:
- Enter the angle of rotation.
- Drag the object around its base point
and specify a point location to which you want to rotate the object.
- Enter c to create
a copy of the selected objects.
- Enter r to rotate
the selected objects from a specified reference angle to an absolute
angle.
To rotate an object to
an absolute angle
-
- Select the objects to rotate.
- Specify the base point for the rotation.
- Enter r (Reference).
- Enter a reference angle value or specify
two point locations.
This determines an imaginary
line that will be rotated to a new angle.
- Enter the new angle, or specify a point.
The value that you enter for the new angle is
an absolute angle, not a relative value. Alternatively, if you specify
a point, the reference angle will be rotated to that point.
To rotate a 3D object around
an axis
-
- Select the object to
rotate (1).
- Specify the start point
and endpoint of the axis about which the objects are to be rotated
(2 and 3).
The
positive axis direction is from the start point to the end point,
and the rotation follows the right-hand rule (see Understand the User Coordinate System in 3D).
- Specify the angle of
rotation.
CommandsROTATE
Rotates objects around
a base point.
ROTATE3D
Moves
objects about a 3D axis.
