CREATE LINE
This function allows the user to draw a 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 line, the user needs to define the location of the points. The INPUT COORDINATE dialog window, Figure 5.1.2, provides various ways to define the location of the points.
1. To create a point of the line at an existing node or point.
Select NODE or POINT option.
Select the location of the node or point. If the POINT option is selected, the following buttons will determine the creation of the point.
At a point of
an existing line near the cursor.
At an endpoint
of a line.
At the midpoint
of a line.
At the
intersection of other lines.

2. 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. See Section 2.5, LOCAL COORDINATE SYSTEM.
Select the XYZ or DXYZ option.
If XYZ is selected, the typed values of U, V and W are the coordinates.
If DXYZ is selected, the typed values of DU, DV and DW are increments of the previously created point.
Type the three values in the corresponding field.
Select APPLY INPUT VALUE to confirm the values and create the point.

3. To cancel the last created point

4. To finish the definition of the line

5. To close the dialog window
