Click the 'Toggle Colour' button which is located on the MODIFY ribbon in the Stands section.
The following dialog will now appear.
Now Select the colour you require for the Stand Lines. You can also select colours that are being used by stand types and zones, plus previously used colours.
Set the line Width as required. Note that the line widths may show differently in EFD than they would on an exported PDF due to scaling, so we recommend changing one stand and exporting a PDF to test, then adjust the width accordingly.
Now just hover over a Stand Line (in the middle) and a little circle with a cross in it will appear, then just click. The stand line will then change to the colour you selected.
If you click on the same line again, it will change back to the original colour.
