I just have a try to reproduce your scenario. Does your job setup by design line? If yes, you are very luck because you can do following steps to make the price information updated. Or else, I think I cannot help you with updating the price information.

After update/Change your price list, you could do:

• Double click the design line to active it.
• Click "Erase 3D Item(s)" icon.

• Check if all information of this design line are disappeared in "Item" tab.

• Go back to "Drawing" tab and click "Fill 3D Item(s)" icon.

• Go back to "Item" tab you may find the price information are updated to the latest.

Hope above information could help you.
