Equipment Model Editor Pop-ups
A collection of handles which together provide a mechanism for positioning and orientation of selected elements. The Locator Handle can be used to drag the entire Graphical Selection to a new position or rotate the entire Graphical Selection through an angle about a selected axis.
The Locator Handle can be moved or rotated independently of the Graphical Selection. This allows you to set a datum for movement and alignment operations, or to set an axis of rotation about which the Graphical Selection will be rotated.
The Locator Handle provides three ways to move or rotate a Graphical Selection: 1. Dragging the linear, planar or rotation handles freehand with the mouse pointer. 2. Aligning with points, P-points, P-lines or straight lines (edges) on other displayed plant
items.
3. Typing in world position, offset distance or angular displacement values.
The Linear Movement Handle
A handle situated on the Locator Handle, which when selected for a drag operation, constrains movement of the selection to be along the direction of the selected major axis
The Planar Movement Handle
A handle situated on the Locator Handle, which when selected for a drag operation, constrains movement of the selection to be in the plane indicated by the planar movement handle. That is the XY, XZ or YZ plane of the Locator Handle
The Rotation Handle A handle situated on the Locator Handle, which when selected for a rotation operation, constrains movement of the selection to be about the axis corresponding to the selected rotation handle

Linear Handle Pop-ups
The following options are available on the Model Editor Handle before a drag.
Enter Value Gives the Move Selection form, enabling you to enter a value to move the graphical selection along the selected linear movement handle.
Align with Feature Allows you to position the Graphical Selection in relation to another object on the screen, but forces the Graphical Selection to move only along the selected axis.
Snap to Point Allows the Graphical Selection to be moved to a Point feature. The Graphical Selection is not constrained to move along the direction of the Linear Handle
Move Handle Allows you to move the Locator Handle, using the same movement options as the main Linear Handle menu. These options move the Locator Handle only, they do not move the Graphical Selection. Alternatively a 'freehand' movement of the Move Handle can be accomplished by clicking the H key with the handle selected and the left mouse button held down.
Moving the Locator Handle independently of the Graphical Selection enables you to change the datum position for the next operation on the Graphical Selection.
Cancel Removes the shortcut menu and deselects the selected Locator Handle.

Rotation Handle Pop-up
The following options are available on the Rotation Handle before a drag:
Enter Value This gives the Rotate Selection About form, enabling you to enter a value to rotate the graphical selection about the selected rotational axis
Orient to Point This allows you to pick a p-line through a point with which to orient the Rotation Handle.
Align with Direction This allows you to identify features with which the handle is to be aligned. Planes will be displayed to indicate a p-point direction (pointer symbol) or a p-line direction (symbol).Clicking and releasing the SHIFT key will reverse the direction of the handle.
Align With This displays the Enter Direction For <direction> Axis form which allows you to align the handle with a specified direction, or as close as possible to the given direction, about the axis of the cable tray.
Rotate Handle Allows you to rotate the Locator Handle, using the same movement options as the main Rotation Handle menu. These options move the Locator Handle only; they do not move the Graphical Selection. Alternatively a 'freehand' movement of the Rotate Handle can be accomplished by clicking the H key with the handle selected and the left mouse button held down.
The Locator Handle may be rotated independently of the Graphical Selection in order to change the frame of reference for the next operation on the Graphical Selection.
Rotate Handle > To World
This option aligns the Locator Handle with the World co-ordinate system, without rotating the Graphical Selection. The Locator Handle Y axis points North and the Z axis points Up.
Cancel This removes the shortcut menu and deselects the selected Locator Handle
