Undo Move/Slide Operations

Certain changes to the model can be undone by using the PlantWise Undo Move toolbox. Only changes that are a result of a Move or Dynamic Move operation from the Plant toolbox, or pipeline components that have been moved as a result of a Slide operation from the Router toolboxcan be undone.

Undo Move Operations dialog

Setting	Description
Undo / Redo List	Both the Undo and Redo lists are top down lists. That is, the most recent move is listed on top, and it is that operation that is undone/redone when the appropriate button is pressed in the toolbox. Note: The operations can also be done from the dialog.
First	Does Undo/Redo the operation that is at the top of respective list.
To Mark	Does Undo/Redo all of the operations in the respective list until a Mark is encountered. Note: If the top entry is Mark, all operations will be undone/redone until the next Mark or the end of the list is reached.
Delete All Previews	Erases all of the lines that were drawn when you have selected Preview from the popup menu.

This dialog can also be used to set marks in the Undo List and it can also be used to clear either list.

The popup menu in this dialog, provides even more functionality.

The menu has seven choices:

Menu item	Description
Execute	Allows any operation to be undone/redone at any time.
Preview	Draws a line from the current location of the component to the location the component will move to if the entry is executed. Note: While preview lines is drawn for pipeline components, it may not always be apparent where the component ends up if the operation is executed. For example, if the operation thaws the inline component, the line will be drawn from 0,0,0 to the current location, but when the model is routed, the component most likely would not be placed at 0,0,0. It may appear that the line is not drawn. If this is the case, check the CAD View Attributes `<Ctrl-B>` and change the Display Style to Wireframe. The line is there, it just is not visible.
Zoom To	Allows you to select any CAD view to have filled by the extents of the selected component.
Highlight	Highlights the selected component in all CAD views. The component remains highlight until you un-highlight it.
UnHighlight	Un-highlights the selected component in all CAD views.
Auto-Zoom To	Causes the last CAD view to receive a data point to zoom, such that the selected component fills that view.
Auto-Highlight	Highlights the component until another component is selected or you un-highlight the component.
