Disassemble separates the current assembly into its component objects or assemblies.
The Disassemble command separates one level, unlike Explode, which separates all levels of nested assemblies.
When you disassemble an assembly, all components of the assembly remain selected, but are no longer part of the assembly. Any transform animation applied to the assembly is lost, and objects remain as they were in the frame at which the dissolution is performed. However, objects retain any individual animation.
All disassembled entities remain in the current selection set.
