Solved: Hi, I use on drawing repeat region with column user defined parameter rel.qty. I need to display my qty parameter in quantity bom ballon. I.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. Press ENTER to start a new line, or press ENTER twice to complete the note. The BoM balloon qty is based on the qty in the BoM table (the total qty of all balloons cannont exceed the qty in the table). This Creo Parametric tutorial shows how to rearrange BOM balloon quantities using the Split, Merge, and Redistribute commands.
