Dimension Relationships • Dimension Relationships • Setting relationship between creating and existing dimensions • Edit Dimension dialog box • Dimensions label (d#) • Prefix fx = value based on parameter or other dimension
Dimension Equations • Dimension Equations • Can be used whenever a value is required • Example.. • (d9/4)*2, or 50 mm + 19 mm • prefixes, precedence, operators, functions, syntax, and units • Help system • Invalid expression • Red
Parameters • Parameters • User-defined name assigned a numeric value, either explicitly or through equations • Multiple parameters • depth = length – width • Anywhere a value is required • Three types • Model parameters • User parameters • Linked parameters
Parameters • Parameters • Parameters dialog box • Model Parameters • automatically • Reference Parameters • driven dimension • User Parameters • manually defined • Column names • Parameter Name • Units • Equation • Nominal Value • Tol • Model Value • Export Parameters Column • Comment
Parameters • To use parameters • Any time of a number is required • Type • List Parameters option in most dialog boxes
Linked Parameters • Linked Parameters • Multiple values & same parameters • Spreadsheet • Microsoft Excel
Linked Parameters • Linked Parameters • Spreadsheet Embedded • no link – no updates • Spreadsheet Linked • will update • more than one can be linked • Guidelines • Edit
Exercise 8-2 • Relationships and Parameters
iParts • iParts • Store parameters and properties information • Create unique parts based on stored information • Example - Bushing iPart • Single file • Table with 3 rows (members) • Unique Hole Dia • Unique Material • Unique Filename
iParts • Creation Stage • Design the part • Establish all possible versions in a table • Each row of the table is a member • Multiple members = iPart Factory • Placement Stage • Select a member from the iPart Factory • Insert the member into an assembly
Types of iParts • Standard iPart (Factories) • Values cannot be modified • Features cannot be added • Custom iPart (Factories) • Unique value for at least one variable • Features can be added
iParts • Creating iParts • Manage tab > Author Panel > Create iPart • iPart Author Dialog • Add parameters • Define Keys • Primary • Secondary (Up to 9)
iParts • iPart Author Dialog • Working with Members • Adding Members > Insert Row • Removing Members > Delete Row • Modifying Members and Setting Default
Creating iParts • iPart Author Dialog • Custom iParts • Custom Parameter Column • Custom Parameter Cell • Specify a value for the parameter upon iPart placement
Default iPart and Options • Set default row • Options • Part Number • Member Name
Creating iParts • iPart Author Dialog • Click OK • The part is converted to an iPart Factory • Table saved as an embedded Microsoft Excel spreadsheet • Table icon is displayed in the Browser
Editing iParts • Operations • Delete table • Converts iPart back to a part • Modify parameters & properties • Add or Delete members • Edit Options • Edit Table • Edit via Spreadsheet • Spreadsheet formulas, conditional statements, etc. are shown as red cells
Placing iParts • Place Component tool • Standard & Custom iPart Placement dialog box • Custom – enter value from the custom column • Folder is created with same name as the iPart Factory • Folder is checked for existing members when placed • Folder is created in same location as the factory by default
Auto-Capture iParts • Create iParts while editing iPart or iAssembly • Edit Member Scope
Drawing From iParts • Create drawing view • Model State tab • Select component
Table From iParts • Table tool • Select a view
Exercise 8-3 • Creating and Placing iParts
iAssemblies • iAssemblies are used to group a set of similar designs in a table format • Assembly Configurations • Similar to iParts • Create within an assembly (iam) file
iAssemblies - Author Dialog Box • Component tab = lists the components of the assembly with configurable items • Member = configuration • Each row = one configuration
iAssemblies - Author Dialog Box • Parameters Tab – Include in the factory: • Constraints • Assembly features • Work features • iMates • Component patterns • Other parameters suchas user parameters
iAssemblies - Author Dialog Box • Properties Tab – Allows the inclusion and modification of: • Summary • Project • Physical • Custom properties
iAssemblies - Author Dialog Box • Exclusion Tab – Similar to the Parameters list, shows all objects that can be excluded, including components. • Can also be set on the Components tab, but provides a more specific way to view and set the exclusion property
iAssemblies - Author Dialog Box • iMate, BOM and Other Tab • iMates • Lists each iMate with offset value, include/exclude, matching name, and sequence number available for configuration • BOM • Specify bill of material specific properties • Other • Specify a custom column that can contains a string value. Custom columns can be designated as keys or as a filename.
Placing an iAssembly • Place Component tool • Place iAssembly dialog box • Folder is created with same name as the iAssembly • Folder is checked for existing members when placed • Change Component • Generate files
Drawing From iAssemblies • Create drawing view • Model State tab • Select an iAssembly Member
Parts List From iAssemblies • Edit Parts List • Select members • Column Chooser
Exercise 8-4 • Working with iAssemblies
iFeatures • Capture design intent • Name • Size • Position • Include Placement Help • Represented with Custom Icons • Stored as separate files (.IDE)
iFeatures • Manage tab > Author panel > Extract iFeature • Extract iFeature dialog box • Selected Features • Size Parameters • Range and Limit • Position Geometry
iFeatures • Insert iFeature tool • Manage tab > Insert panel • Insert iFeature dialog box • Select • Position • Size • Precise Position
iFeatures • Editing iFeatures • Open the .ide file in Autodesk Inventor • Edit iFeature • View Catalog • iFeature Author Table • Edit iFeature • Opens the Edit iFeature dialog box • Cannot change parameters • Can modify size parameters and position geometry • Name • Value • Limit • Prompt
iFeatures • Table-Driven iFeatures • Open the .ide file in Autodesk Inventor • iFeature Author Table • iFeatures behave similar to iParts • Main difference: No File Name, Display Style or Material column designations
Exercise 8-5 • Creating and Placing iFeatures
Applying Your Skills • Skill Exercise 8-1
Checking Your Skills • iMates are created while inside of a part file. • What needs to be selected to have a single component containing iMates be placed and automatically constrained in an assembly? • Automatically Generate iMates on Place • Place Component with iMate • Interactively Place with iMates • Use Composite iMate • When creating parameters in a spreadsheet, the data items must be in the following order: parameter name, value or equations, unit of measurement, and, if needed, a comment. • What is the difference between a model parameter and a user parameter? • Multiple versions of an iPart can be placed in an assembly. • When you make changes to an iPart factory, the changes are updated automatically in iParts that have been placed in assemblies. • Which tab of the Place iPart or iAssembly dialog box can be used to create a new member of the factory during placement in an assembly? • Keys • Table • Tree • None of the above • You can add features to standard iParts after they have been placed in an assembly. • Named parameters are added automatically as Size parameters during iFeature creation and cannot be removed. • What happens when you create a table-driven iFeature and one of the original parameters contains a list of values for the parameter?
