This function allows the user to draw a straight line. In eta/DYNAFORM, a line is formed by a sequence of points and is displayed by the set of straight line segments between adjacent points in the sequence. To create a straight line, the user has to define the location of two points, following by connecting these points. Various methods of creating points are described below.
1. To create a point of the line at an existing node or point.
•
Select NODE or POINT option
from the INPUT COORDINATE dialog box as illustrated in Figure
• Select the location of the node or point. If the POINT option is selected, the following buttons is used to determine the generation of point.
At a point
of an existing line close to the cursor location.
At an endpoint of a
line.
At
the midpoint of a line.
At
the intersection of two lines.
On the workplane. Click on the workplane icon to display the
grids on the display area and activate Workplane and Grid Setting button. The
user can generate a line on the workplane by clicking the left mouse button on
two or multiple points.

WORKING PLANE AND GRID SETTING
The user can define the setup of the workplane and
grid from the Grid Setting dialog box as illustrated in Figure
PLANE COORDINATE:
Set the direction of the workplane, the default workplane is x-y plane of the Globe coordinate system. The user can select the coordinate plane of the view direction or LCS from the list as the current workplane.
LIMIT BOX:
Set the size of the grids displayed on the workplane. The user can define the maximum and minimum coordinate of the display grids.
DIVISION
Set the width of the grid division.

1. To create a point by its coordinates.
• Select the LCS or ABS option for the coordinates in the current local coordinate system or global system. Refer to Section 11.15, LOCAL COORDINATE SYSTEM.
• Select the XYZ or DXYZ option.
If XYZ is selected, the input values of U, V and W are the coordinates.
If DXYZ is selected, the input values of DU, DV and DW are increments of the previously created point.
• Type in each value in the corresponding field.
• Select APPLY INPUT VALUE to confirm the values and create the point.
2. To cancel the last created point
• Click REJECT once.
3. To finish the definition of the line
• Select OK or click on the middle mouse button.
4. To close the dialog box
• Select CANCEL or click on the right mouse button. The selected points will be ignored when the CANCEL button is selected.
