The following approaches are used for designing assemblies:
•top down design,
•bottom up design.

Top down design schema
If the top down design is used:
•design starts at the top level and ends at the bottom levels;
•components are typically created in the context of an assembly.
Bottom up design

Bottom up design scheme
If the bottom up design is used:
•design starts at the bottom levels and ends at the top level,
•component development is typically performed in separate windows, outside the context of the assembly,
•completed components are placed in the assembly (subassembly).
The following design methods are used for the approaches described above:
•Top down design with pre-detailing,
•Top down design with the 'solid-component' conversion,
•Bottom up design with pre-detailing,
•Bottom up design with components placement.
These methods help to select the proper scenario for assembly development. In practice, several methods are usually combined during the assembly development.
