A solid body that exists within an assembly document.
Several operations in Solid Edge create assembly bodies, and they can be broken down into two types: assembly bodies, and override bodies.
An assembly body that is created from scratch in the assembly document. For example, when you create a weld bead protrusion or an assembly feature which adds material in a weldment assembly, a solid body is created that exists only within the context of the assembly document. A wire harness body is also an assembly body.
An override body has an underlying part or sheet metal document that is used as the basis for the solid geometry. Operations that create override bodies include: assembly material removal features, adjustable parts, frames, and pipes.
Override bodies use a copy of the underlying part geometry, then modify it within the context of the assembly to display it properly. For example, when you create an assembly cutout feature, an associative copy of the solid geometry on the original part is added to the assembly, then the cutout is applied to the assembly solid geometry to display the modified component.
