A line locator can exist between two points anywhere inside or outside the domain.
The following characteristics of lines will be discussed:
Note: There are several ways to insert a line:
From the menu bar, select Insert > Location > Line.
From the toolbar, select Location > Line.
Depending on the context, you may be able to perform an insert from the shortcut menu in the tree view.
For details, see Domains.
Selecting Cut will extend the line in both directions until it reaches the edge of the domain. Points on this line exist where the line intersects with a mesh element face.
Tip: In cases with very thin elements near a boundary, a cut line normal to the boundary may stop too early and not quite reach the boundary. To correct this, you can set the environment variable CFX_CUT_LINE_TOLERANCE before starting CFD-Post. For example:
CFDPOST_CUT_LINE_TOLERANCE='1.0e-8 [m]'
The smaller the number, the more likely it is that the line will reach the boundary. However, if it is too small, the line could end up with a number of coincident (repeated) points.
Selecting Sample creates a line existing between the two points entered. It is mesh-independent, and the number of points along the line corresponds to the value you enter in the Samples box.
You can use picking mode to select or translate a line in the
viewer. To move a line, select picking mode by clicking Single Select 
in the Selection Tools toolbar and drag the line to a new location. The line properties
will automatically update in the details view. For details, see Picking Mode.
The color settings can be changed by clicking the Color tab. For details, see Color Tab.
You can change the Line Width by entering a value corresponding to the pixel width of the line. You can specify the value between 1 and 11 by using the graduated arrows, the embedded slider, or by typing in the value.
The View tab is used for creating or applying predefined Instance Transforms for a wide variety of objects.
For details on changing the view settings, see View Tab.
