 Check the new version of the Sketchup Extension Pipes Tubes Profiles 2020. New feature added. Now you can change the starting index of automatic part numbering. Go to the settings dialog window and set numbering start index. When you create a new part, the extension will automatically name its starting from that number. After you change the setting, the next part number will start from the new value. Look at the outliner tray on the right side and see how every next part is named. During your work, you can change the numbering start index as you need to stand out some specific parts from the project. When you create new part withdrawal tool or by making tubes from bunch of edges, extension will assign names with not used numbers starting from index you have set.
