This button will generate a grid within the area enclosed by the splines. The number of cells in the I and J direction will depend on the user's input in the Operations toolbox. | |
This button allows the user to insert one or multiple cells within the generated grid. There two options in the drop down menu as shown in Figure 4 673. Insert a Cell will add one cell at a time to the generated grid. To add a cell, click just outside the grid where the extra cell is desired. The new cell will be added and connected to the nearest cell(s). Insert a Multiple Cells will add a number of cells to the generated grid by selecting two nodes on same marginal grid line. The new cells will be added and connected to the nearest cell(s). | |
This button allows the user to delete one or multiple cells within the generated grid. There are a number of options in the drop down menu as shown in Figure 4 68. Delete a Grid Node will immediately delete the node of a cell selected by the hand icon. Delete Nodes Inside a Polygon allows the user to create a polygon with LMC. Closing the polygon with a RMC will delete multiple cells inside the polygon. Delete Nodes Inside a Block is used by clicking two nodes to indicate the corners of the grid block that you want to delete. A block is selected which just contains the selected nodes. Clicking the second node will delete all cells of the block area. Delete Nodes Outside a Block is used by clicking four nodes to indicate the corners of the grid block. A block is selected which just contains the selected nodes. Clicking the fourth node will delete all cells in the area outside the selected block. Deactivate Line of Cells: Instead of deactivating cell by cell on the grid, select this function then draw a line by LMC in order to intersect multiple cells. RMC to end the line and multiple cells along that line will be deactivated. | |
This button will move nodes on a grid. To move a node on the grid, LMC on the desired node then LMC on the position it should be moved to. Any line connected to that node will move also. | |
Delete the entire grid selected. Simply click this icon and then select the grid to delete. Note: any grid connected separately to the grid selected will also be deleted. | |
Select a grid so that it can be edited. If there are several grids in the workspace that are not connected the user will only be able to edit one at a time. This icon selects a grid and makes it active for editing. | |
