As a reminder for LogoPress users, the “Reference part” is the part that you are designing the die for. It is what the strip and the tool revolve around, so to speak, and it is the one part file in the strip and tool that does not get a project number. The “Annex part” is the part whose name always ends with “_for_strip”.
The steps to rename a “Reference part” in LogoPress are very similar to those found in the previous post called “Create a new tool from a previously created tool“.
