After selecting Delete Selected GAD Objects from the pull-down menu, and clicking the Edit… button, the Delete Selected GAD Objects dialog opens.

Decide whether to delete objects with a certain material ID, a certain material, or a certain object type. Then select the material ID, the material, or the object type from the pull-down menus. Click OK to return to the GadGeo section. Click Run to delete the objects in the structure according to your choice. It is possible to check multiple of the possibilities.

Observe the disappearance of the objects with type ShortCircularFiber (here shown in grey) in the structure.
