The following tools are active in the dynamic portion of the Tool Palette whenever the Curvilinear Grid Module is active. Only one tool is active at any given time. The action that takes place when the user clicks in the Graphics Window with the cursor depends on the current tool. The table below describes the tools in the Curvilinear Grid tool palette.

Tool	Tool Name	Description	Right Click Menu
File:Create node icon.bmp	Select Curvilinear Grid Node	The Curvilinear Grid Node tool is used to manually selected an individual node. A second node can be added to the selection list by holding the SHIFT key while selecting it (Not implemented yet). Multiple nodes can be selected at once by dragging a box around them. A selected node can be deselected by holding the SHIFT key as it is clicked.	N/A
File:Select node icon.bmp	Select Element	The Select Element tool is used to select the element. A single element is selected by clicking on it. A second element can be added to the selection list by holding the SHIFT key while selecting it. Multiple elements can be selected at once by dragging a box around them.

File:CreateMeshNodestring icon.bmp	Create Nodestrings	The Create Nodestrings tool is used to create node string. Nodestrings are used for operations such as assigning boundary conditions, forcing breaklines into the mesh, and renumbering the mesh. To create a nodestring: Click on a node. The node will be highlighted in red and a prompt will be shown in the Help Window. Click on any node to add it to the nodestring. The selected node is also highlighted in red and a solid red line is drawn between the two nodes. Continue adding nodes to the nodestring in this manner. Note: For most operations, nodes in the nodestring should be adjacent, but this is not required. Press the BACKSPACE key to backup one node. Press the ESC key to abort the nodestring creation. Double-click a node or press the ENTER key to end the nodestring creation. The SHIFT and CTRL keys assist in creating large nodestrings which are made up of adjacent nodes. These can be used after at least one node has been selected and function as follows: SHIFT. Holding down the SHIFT key and selecting another node will add to the nodestring all nodes between the two. The path chosen is the shortest distance between the two nodes. This is useful for creating continuity strings which run along a cross section of the mesh. CTRL. Holding down the CTRL key and selecting another node will add to the nodestring all nodes on the mesh boundary between the two, going counter clockwise from the first node to the second node. Both nodes must be on the boundary of the mesh or SMS will beep. CTRL + SHIFT. Holding down both the CTRL and SHIFT keys and selecting another node will add to the nodestring all nodes on the mesh boundary between the two, going clockwise from the first node to the second node. Both nodes must be on the boundary of the mesh or SMS will beep.	N/A
File:SelectMeshNodestring.bmp	Select Nodestrings	The Select Nodestrings tool is used to select nodestrings. A nodestring is selected by clicking on it or by dragging a box around it. A second nodestring can be added to the selection list by holding the SHIFT key while selecting it. Multiple nodestrings can be selected by dragging a box around their icons. A selected nodestring can be deselected by holding the SHIFT key as its icon is clicked. The Edit Window shows the number of nodestrings selected.	See the right click menu options for each module.
