Select the stand(s) you would like to change the Edges and Walls line colours for then click the 'Calculate Colour' button which is located on the Dynamic ribbon.
NOTE: The Dynamic ribbon will not appear if you have entities other than stands selected, to deselect the other entities and only select stands, press F3 twice.
The following dialog will now appear.
Now Select the colours you require for the Stand Edges and Walls. 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 creating a PDF to test, then adjust the width accordingly.
