Move Connection: Available for the connection node of a selected straight element connected to another straight element.
Use the cursor to drag the connection node, or enter values in the Tracker; this modifies the length of the segment. (The Length parameter is the length of the element; the Distance parameter is the distance by which you move the node.)
Insert Node: Available for every straight MEP element, by clicking on its edge. This command will affect not just the selected MEP element, but all straight connected elements up to the next connected junction, or to the last straight element. New bends are inserted as needed.
Offset Edge: Available for every straight MEP element. Affects all straight elements connected to the clicked element, including any inline, transition and junction elements.
Elevate Edge: In the 2D window, this Pet Palette command brings up the Elevate dialog box. Enter the value by which you wish to elevate the selection.
Since this is a vertical edit, you will have no feedback in the Floor Plan on the result, unless a previously connected straight segment is now disconnected: the hotspots will change.
Stretch: Available at the end of an unconnected straight segment.
