Follow the steps below to add or change an order code for a non-standard item and installation symbol:
1. Go to Insert Non-Standard.
2. You will now see there is an order code field for you to add to.
3. If you've already created your order code and want to change it, you can simply click in the description of the non-standard item and change the order code when the item has been selected.
4. To add an order code for an installation symbol, it works exactly the same as in step 3, except you just select the installation symbol item instead.
