OPEN CURVE (Fills in an open area)
กก
This function allows the user to fill in elements in a cut out area. Figure 6.1.25 shows the result of filled mesh using a spline curve to close the opening.

Figure 6.1.26 Open Curve Options
Select the OPEN CURVE option, and the program will prompt the user to select elements near the expected fill area.
Select OK to accept the selected elements, and a window will be
displayed, as shown in Figure 6.1.26, to prompt the user to select one of
the following methods to fill the area.
SELECT NODES
This option allows the user to select a set of nodes to define the
boundary to close the open curve for filling.
SELECT LINE
Allows the user to select an existing line as the outer boundary to
close the open curve for filling. After a line is selected, the program
displays the SELECT NODES window and prompts the user.
SELECT TWO NODES TO SPLIT THE LINE, OR PICK OK TO USE THE ENTIRE
LINE
After selecting two nodes, the line segment between the selected
nodes will be used as the boundary to close the open curve.
CREATE LINE
This option allows the user to create a line as the outer boundary to
close the open curve for filling. After a line is created, the SELECT
NODES window will be displayed.
SELECT TWO NODES TO SPLIT THE LINE, OR PICK OK TO USE THE ENTIRE
LINE
After selecting two nodes, the line segment between the selected nodes
will be used to close the open curve.
CREATE SPLINE
Allows the user to create a spline curve as the outer boundary for
fill mesh. After the spline is created, the program will display the
SELECT NODES window and prompt the user with the following message.
SELECT TWO NODES TO SPLIT THE LINE, OR PICK OK TO USE THE ENTIRE
LINE
After selecting two nodes, the spline segment between the two points
will be used
After the curve is defined by any of the above methods to close the region, the program will fill in a set of elements within the region.
