About Performing a Fastener Analysis

Clicking Fasteners analysis preferences displays the Fasteners Analysis Preferences dialog box.

The Display options are selected as specified in Me > Preferences > App Preferences > 3D Modeling > Multi Discipline Engineering > Fastening > Display. You can modify them. For more information, see Fasteners Analysis Options.

The information used to perform analyses is stored in a cache. The Clear cache option lets you manually clear the cache. The cache is filled when performing an analysis, provided that the colors or labels are displayed.

The cache is automatically cleared when a filter is applied or when running the Collapse and Refresh command.

Fasteners Analysis provides different analysis options. To analyze a fastened part, you need first to specify an analysis mode.

The mode qualifies the expected results of the analysis and is specified by two parameters.

There are several analysis modes to analyze fastened parts and a complementary mode.

• A1: Find core fasteners, each involved with the whole set of selected items:

  The retrieved fasteners are the ones that connect the selected parts and all its connected parts that are in the user selection. It corresponds to the fasteners defined between the parts in the core of the whole selection.

• A2: Find core fasteners, each involved with any selected items:

  The retrieved fasteners are the ones that connect at least one of the selected parts and, for each one, all its connected parts are in the user selection. It corresponds to the fasteners defined between the parts inside the selection.

• B1: Find boundary fasteners, each involved with the whole set of selected items:

  The retrieved fasteners are the ones that connect all the selected parts together and at least one of its connected parts is not in the user selection. It corresponds to the fasteners defined at the boundary of the whole selection.

• B2: Find boundary fasteners, each involved with any selected items:

  The retrieved fasteners are the ones that connect at least one of the selected parts and, for each one, at least one of its connected parts is not in the user selection. It corresponds to the fasteners defined at the boundary of the selection.

• C1: Find any fasteners, each involved with the whole set of selected items:

  The retrieved fasteners are the ones that connect at least all the parts selected by the end user.

• C2: Find any fasteners, each involved with any selected items:

  The retrieved fasteners are the ones that connect at least one of the selected parts.

• Number of fastened parts for each fastener:

  The retrieved fasteners are the ones that connect exactly the specified number of parts. This number must be equal or greater than 1.

  Note: This analysis mode acts as a filter. You have to select first one of the above analysis modes, select the option. It is cleared by default.

• Only fasteners with broken links

  The fasteners retrieved by the analysis are only the ones that have broken links.

• Spot Fastener Single: if selected, the analysis takes spot single fasteners into account.
• Spot Fastener Assembly: if selected, the analysis takes spot assemblies into account. It also includes spot assembly with secondary and flexible fastener types.
• Bead Fastener: if selected, the analysis takes bead fasteners into account. It also includes unified bead and simple bead fastener types.
• D1: Find fasteners positioned by any selected items:

  The retrieved fasteners are the ones that are positioned by at least one of the selected parts.

There are four search modes to analyze fastened parts:

• A: Find all fasteners directly under selected items:

  The retrieved fasteners are all those that are located directly under the selected parts.

  Note: If the selected product node has never been expanded, the fasteners located directly under this product will not be retrieved; if a fastener node has been removed, it will not be retrieved either.

  Number of fastened parts for each fastener: The retrieved fasteners are the ones that connect exactly the specified number of parts. The number is a positive integer and cannot be zero.

  Only fasteners with broken links: The retrieved fasteners are the ones that have broken links.

• B: Find all fasteners among selected items:

  The retrieved fasteners are all those that can be found among the selected parts.
