All part features should be unsuppressed when releasing (making the final version) the part.
Part must have material property and color assigned
Part must not be in roll-back mode
Features and sketches must be named
All sketched must be fully defined
Use mm, N, s, K units (important for analysis)
Zoom to fit and position in isometric view (or other meaningful view) before saving

ASSEMBLIES
Assembly of 3D solid modeling software in general does not
contain “assembly” geometry. The assembly contains
components (i.e. parts and lower level assemblies) assembled
together in the intended manner.
Assembly contains information on where to find parts and how
are parts oriented relative to each other (mated).
The only features that can be defined in assembly are “negative”
features (cut)

ASSEMBLIES
When retrieving the assembly (opening assembly file), CAD program needs the following information:
- BOM (Bill of Material) structure: This information is stored within assembly file and is used to retrieve all listed components. It is obvious, that the system has to be able to “see” and retrieve all components regardless where they reside on the network.
- “Mating” information: How feature surfaces of individual components are assembled - mated to their parent components.
- Feature information: Assembly cuts (in case they have been created) and parts/features that are being intersected by them.

ASSEMBLIES
An assembly structure can have as many lower assembly levels as needed. They should reflect the logical structure of the designed product.

FILE MANAGEMENT
Be careful moving assembly files, do not destroy relations between assembly and components.
Use “Pack and Go” feature to keep relations while moving files
