Sets options for rotating objects in the model. You cannot rotate objects with certain constraints. For example, you cannot rotate a pump that is mated to a horizontal reference plane and aligned with other pumps on either side. That rotation would violate at least one relationship.

Axis direction

Defines the direction of the axis of rotation. You can select one of the predefined axes or specify a different direction. The following graphic shows the default rotation coordinate system for an object. The axes are parallel to the axes of the active coordinate system. The default origin of the coordinate system is the connect point of the object.

To choose a different axis direction, you can complete one of the following actions:

  • Select one of the axis directions parallel with the active coordinate system (Up/Down, N/S, or E/W) from the Axis direction box. Or, select an axis directly on the rotation triad graphic in a graphic view.

  • Select Perpendicular to both References to use the rotation axis direction perpendicular to both a reference on the object and a reference in the model. This allows a single rotation about the axis at the rotation point to make the two references parallel. Generally, the Angle will be set to 0.

  • Select Select Graphically, and then click the line or port about which to rotate the object in the graphic view. You can also select a cylinder to define the axis of the cylinder as the axis of rotation. If a line is selected, the line becomes the axis of rotation for the object. If a port is selected, the axis position point changes to the coordinate system origin of the port.

Bearing

Specifies the bearing angle for the object. The Bearing angle is measured between the local x-axis of the object and the Y-axis (North) of the global coordinate system in the XY-plane. The local x-axis is the default axis of primary symmetry for all symbols in the catalog. The bearing measurement direction is clockwise from the active coordinate system North looking in the negative active coordinate system direction; that is, down from 0 to 360 degrees. You can enter negative bearing angles, but the software automatically converts them to the positive equivalents. If the pitch is set to +/- 90 degrees, then the bearing measure displays 0 degrees.

Bearing Rotation

Pitch

Specifies the pitch angle for the object. The Pitch angle measures between the x-axis of the object and the X-axis of the global coordinate system in the XZ-plane. This option sets the reference in the model to a line that is the intersection of the vertical plane through the X-axis of the local coordinate system and the active coordinate system horizontal plane. The angle is measured in the positive direction from the horizontal plane in the active coordinate system up direction regardless of the current bearing. Another way to describe pitch is the rotation of the object about its y-axis. Pitch angles are limited to between -90 degrees and +90 degrees, with 0 indicating horizontal.

Pitch Rotation

Roll Angle

Specifies the roll angle for the object. The Roll angle measures between the local z-axis of the object and the Z-axis of the global coordinate in the YZ-plane. Another way to describe roll is the rotation of the object about its x-axis. This option sets the reference in the model to a line that is perpendicular to the local coordinate system x-axis and in the horizontal plane. Roll angles are measured clockwise from horizontal to the y-axis of the local coordinate system. The roll angle is between 0 and 360 degrees. You can enter negative roll angles, but the software automatically converts them to the positive equivalents. If the pitch is set to +/- 90 degrees, then the reference in the model is the North axis.

Roll Rotation

Axis Position Point

Defines the origin point for the axis of rotation. This point is stationary during the rotation, as is any point on the axis of rotation. To move the axis of rotation to a different location in the model, you can click Axis Position Point, and then click in the graphic view at the location of the origin. The default is the object origin. If there is no defined origin, the origin is the center of the range of the selected objects.

Reference on Rotation Object

Instructs the software to use the selected part face or edge as the rotation reference, and sets the local coordinate system for the rotation of the object. The Angle box displays the angle between the selected references as projected against the measurement plane.

Reference on Stationary Object

Defines a reference plane or line on another object in the model and selects the global coordinate system for the rotation of the object. The Angle box displays the angle between the rotation object and the stationary object as projected against the measurement plane.

Rotate by precision graphic input

Allows you to click a point in the model to graphically orient the object. You can use the SmartSketch relationship indicators to locate the point.

The following picture shows a graphic input point (E) and reference lines (C) and (D).

(A) - Selected object
(B) - Rotation point
(C) - Reference line on selected object
(D) - Reference line on object in model
(E) - Graphic input point
(F) - Rotated position of reference line on selected object

Angle

Allows you to type the number of degrees for the angle of rotation to apply to the object. This option also dynamically displays the current angle during manual rotation. This option is helpful if you need to have a precise value for the rotation angle.

When you use a reference plane or line on the rotation object and a reference plane or line on a stationary object in the model, the Angle box shows the angle between these two references.

Step

Defines an incremental or step value for dynamic rotation. When you rotate objects, the object rotates to an angle equal to some multiple of the step value.

Close

Completes the command.

Fast rotate

Displays a range box around the objects that you are rotating instead of the wireframe outline of each object. This option enhances performance when working with large select sets.

If you do not want to view all of the objects in your workspace during rotation, you can use Tools > Hide to remove unwanted objects from the view. To restore the objects to the display, click Tools > Show.
