Moves an element (identified as the CE), so that its obstruction volume or P-point is a specified clearance from another element.
You must first select the element to be moved in the Model Explorer or in the 3D graphical view. On the Home tab, in the Common group, click Position Relatively By, select Move from the drop-down list to display the Move window with the Clearance tab displayed.
The obstruction volume or P-point to clear the reference point must be selected first:
The Parameters pane displays the following options:
From the Origin drop-down menu select All to use the obstruction volume or select Origin or a P-point to use as the reference point for the move.
Enter a Clearance value, the value is used together with the option selected from the Relative To options.
Enter the Direction of movement and an element in the WRT field that defines the frame of reference for the direction. You can select WRT from the following options:
|
|
Select Current Element as WRT Element |
|
|
Select Current Element Owner as WRT Element |
|
|
Select World as WRT Element |
|
|
Pick WRT Element |
The Target pane displays the following options:
The Relative To drop-down list specifies how the element is positioned in relation to the target element or position:
|
In Front |
The origin of the CE is moved In front of the surface of the reference element. There must be a plan component in the direction |
|
Behind |
The origin of the CE is moved Behind the surface of the reference element. There must be a plan component in the direction. |
|
On top |
The origin of the CE is moved On top the surface of the reference element. There must be an elevation component in the direction |
|
Under |
The origin of the CE is moved Under the surface of the reference element. There must be an elevation component in the direction. |
|
From |
The origin of the CE is moved until it is the specified distance From the origin of the reference element. |
|
Towards |
The origin of the CE is moved until it is the specified distance Towards the origin of the reference element. |
Select Plane Through Target check box to allow the current element to be moved in a given direction until it hits a reference plane offset by the given Clearance from the target item. Enter the direction of the plane normal into the Plane field text box. The plane must not be parallel to the direction of movement. The position of the plane is defined by its Clearance distance in relation to a reference point. The reference point is specified by the Relative To drop-down list. The plane passes through a point, the given distance In front of, Behind, Under or On top of the reference point.
The type of target item is specified by the Select drop-down list. The target can be a geometry element or a position. The following options are available:
|
Element |
Click Pick Target Element icon and pick a target element on the 3D view, to populate the Name field. Click Apply. |
|
Position |
Click Pick Target Position icon and pick a target position on the 3D view for graphical highlight of the selected position. Click Apply. |
|
Next |
Piping only, you can move the CE in the specified direction until the obstruction volume or a P-point is the given clearance from the reference point (Next element in the Model Explorer). Click Apply. |
|
Tail |
Piping only, you can move the CE in the specified direction until the obstruction volume or a P-point is the given clearance from the reference point (Tail of branch which contains the CE). Click Apply. |
|
Previous |
Piping only, you can move the CE in the specified direction until the obstruction volume or a P-point is the given clearance from the reference point (Previous element in the Model Explorer). Click Apply. |
|
Head |
Piping only, you can move the CE in the specified direction until the obstruction volume or a P-point is the given clearance from the reference point (Head of branch which contains the CE). Click Apply. |
|
Current |
Piping only, you can move the CE, the specified direction until the obstruction volume or a P-point is the given clearance from the reference point reference point. Click Apply. |
