The Edit menu on the main menu bar works in conjunction with Model Editor Mode.
Most of the options are similar or are the same as those available from other buttons or via the pop-up menus from the Locator Handles.
The Edit menu has the following options:
Model Editor – this option toggles Model Editor Mode on and off. If on, a check mark appears next to the menu entry.
Undo and Redo – these options Undo or Redo Model Editor actions. These options are only active when Model Editor Mode is on.
Re-Select – this option re-selects the previous Graphical Selection, if any. This option is only active if Model Editor Mode is on.
Move Selection – this option has a sub-menu:
The sub-menu has the following options for moving the Graphical Selection:
Offset in 3D… - this option displays the Move Selection form.
Entering values in any of the three axis textboxes moves the Graphical Selection using the Locator Handle as the frame of reference.
Clicking the Preview button shows the affect of the entered value and clicking the OK button moves the Graphical Selection.

The sub-menu has the following options for rotating the Graphical Selection:
To World – this option re-orientates the Locator Handle and the Graphical Selection such that the Y axis of the Locator Handle points in the World North direction and the Z axis points in the World Up direction.
About X…, About Y… and About Z… – these options display the Rotate Selection about X/Y/Z form, depending on the axis selected.
Entering a value in any of the textbox rotates the Graphical Selection and the Locator Handle around the specified axis.
Clicking the Preview button shows the affect of the entered value and clicking the OK button moves the Graphical Selection.
Move Handle – this option has a sub-menu:
The options on this sub-menu are the same as for the Move Selection sub-menu described above, except that they apply to the Locator Handle only.
Rotate Handle – this option has a sub-menu:
The options on this sub-menu are the same as for the Rotate Selection sub-menu described above, except that they apply to the Locator Handle only.

Nozzle (NOZZ)
Although a nozzle is classed as a primitive, it is unlike the other primitives in that its geometry is determined in Paragon as part of a catalogue component. Nozzles of different types and geometry may be constructed in Paragon to suit the requirements of the Piping Specification.
The specific nozzle type is referenced from Paragon using the Specification Reference (Spref) attribute.
Specific geometric attributes:
Height Height between nozzle face and end, i.e. from P1 to P2.
