Welcome to Forum.
You are wright, after deleting BOM the numbering system changed get changed back.
What you can do, hide you BOM by right clicking on the BOM or move you BOM far the drawing sheet
Hope this help
Satish is right in what he said. Another method is in the property manager
of the balloon you will see a selection that allows you to change the content
of the balloonand over write the item number and type in what you want.
The problem with this method is you lose your parametricness.
Hi Satish and Scott,
Thanks for helping. I thought there is a method to save item number after i modified them in the BOM.
