Correcting mistakes When defining keypoints, lines, areas, volumes,
elements, constraints, and loads, you are bound to make mistakes. For-
tunately, these are easily corrected so that you do not need to begin from
scratch every time an error is made! Every Create menu for generating these
various entities also has a corresponding Delete menu for fixing-up things.
3. Form lines; the keypoints must now be connected. We will use the
mouse to select the keypoints to form the lines. In the main menu,
select:
Preprocessor > Modeling > Create > Lines >
Lines > In Active Coord.
The following window will then appear:
Use the mouse to pick keypoint #1 (i.e., click on it). It will now be
marked by a small yellow box.
Now move the mouse toward keypoint #2. A line will now show on
the screen joining these two points. Left-click and a permanent line will
appear.
