Hi,
Before any structure objects are created, the "Enable Mechanical Structure"
checkbox (2006 and below) can be checked/unchecked. However, after structure
has been initialized, usually by creating structure data, the checkbox will
be greyed out and cannot be unchecked thereafter. This is to prevent losing
structure data.
When you save as a lower version like AutoCAD Mechanical 2002, the structure
data will be saved to geometry automatically. When opened in 2002, the
drawing will be shown with the exact geometry, except without structure.
There is no need to remove the structure data manually.

Save as AutoCAD/Mechanical 2002 or below. Structure is not available then.
