The Cylinders section of the Visibility on Photos pane controls whether 2D cylinders (marks on photographs) and 3D cylinders (or projections) are visible on the open photographs.
The Cylinders section will only appear on this pane if at least one cylinder has been marked in the project.
When PhotoModeler is in Cylinder marking mode the cylinder mark type is forced to be visible.
Note: 3D items are displayed on oriented photographs only. See the section on Photo Projections for more information.
