Part design
intent
Basic guidelines
- Set up dimensional relationships
in the part model as you wish the dimensions to appear on the
2D manufacturing drawing.
- To create new part models similar
to an existing model use the "save as" command. Edit
the copied model as needed.
Family tables
- Use family tables when creating
three or more part models that are similar but vary in some fundamental
way such as overall length or number of holes.
- When modifying parts with family
tables, be sure all instances are present in your workspace.
- Use the "verify" command
before checking in new or modified part models with family tables.
This makes all instances visible in commonspace (instances are
created from the generic model, they do not have physical object
files).
Parametrics
- Part geometry is driven by five
factors: parent-child dependencies, user created relationships,
family tables, skeletons, and Pro/PROGRAM routines. To avoid
reworking your part models, plan your strategy before you start
modeling.
- Rename key dimensional parameters
with meaningful names. This makes it easier to identify the parameters
when writing relationships, setting up family tables or Pro/PROGRAM
routines.
- Test your part models. Flex
part geometry by modifying key driving parameters and checking
for the expected results.
