You can use the Show Removable Loops feature prior to meshing to view loops that will be removed according to the criteria defined by the global Sheet Loop Removal and Loop Removal Tolerance controls.

This feature applies only to sheet models, and it responds only to the settings of the global loop removal controls. For example, if you set loop removal controls locally and your model contains loops that will be removed according to your local criteria, the Show Removable Loops feature will return nothing if the global Sheet Loop Removal control is off (set to No).
