Sometimes, when the layer structure of a file allows for it, it can be useful to collect all Thin Parts objects in one place/ layer for easier editing. The objects can be spread out in many layers and therefore hard to find when you want to relocate them.
To select your Thin Parts objects you can:
Open the Select by Attribute dialogue via Select > Select by Attribute....
Check the Object Type check box and select Thin Part Fix* in the drop down menu.
Click the Select All button at the bottom of the dialogue.
