Selection Grid

The diagram is entered in a logical grid, and all objects are snapped to the grid.

• Use the commands of the View menu to see hiding grid points.
  • This helps locate errors detected by the compiler or aligning objects in the diagram.
• Zoom in or out of the edited diagram.
  • See Use the Free Form Ladder (FFLD) Editor for more information.
• Drag the separation lines in vertical and horizontal rulers to freely resize the cells of the grid:

       

• 
  

• If a split window is in use, the zoom applies only to the currently selected split window (each split window can be zoomed to different levels).

• The current position in the grid is always highlighted by a dotted cell .
  • Its coordinates (row, column) are displayed at the bottom left-hand corner of the editor.
• Click on the current position, the cell is drawn as gray, meaning that it can be dragged somewhere else in the diagram.
  • Select multiple cells with the mouse, or use the arrows of the keyboard with the SHIFT key pressed.
• Click the power rail (gray ruler at the left border) to select a full row.
