In this video we are going to see how to add Balloons with quantity in care drawing. In this video Let's create Balloons with quantity in assembly drawing.I need to display my qty parameter in quantity bom ballon. I tryed to modify bom balloon symbol, but it doesnt work. This is the way you can create custom balloons in cre parametric and you can use multiple symbols as a custom balloon in the same drawing. BOM balloons are circular callouts in an assembly drawing that show Bill of Materials information for each component of an assembly view. This Creo Parametric tutorial shows how to rearrange BOM balloon quantities using the Split, Merge, and Redistribute commands. I'd like to know if it's possible to get my BOM balloons to display a total quantity rather than the quantity which the balloon is pointing to. This Creo Parametric tutorial shows how to create custom symbols for use as BOM Balloons in a 2D production drawing.
