Fasteners

Use the Fasteners to connect parts together using bolts or screws. Fasteners don't allow movement at the hole location. You can search for single or aligned holes and create fasteners in all of the selected holes as a group, or you can select holes and create fasteners individually. This tool can be accessed by clicking the Structure tab on the ribbon.

Inspire automatically finds holes within a default size range that is calculated based on the geometry of your model. Click the bolt_find_options icon on the guide bar and select Options to specify a different range. You can also select and deselect individual holes by holding down the Ctrl key and left-clicking on the hole.

Click Fasten All on the guide bar to automatically create fasteners in all of the selected holes. The tool automatically places nuts and bolts in through holes and screws in blind holes. You can also create fasteners individually by clicking on selected holes. Once created, you can change the type of fastener and its direction by selecting the fastener and using the options in the microdialog. Bolts and screws impart different loads that will have an impact on the analysis and optimization calculations.

Open the options below for detailed instructions.

To find holes where fasteners can be created:
  1. Select the Fasteners tool.
  2. A guide bar appears and the find operation is executed automatically. By default, the tool automatically finds aligned holes and displays them in red. The total number of holes is displayed in a counter above the Fasteners tool.
  3. To find single holes, change the filter on the guide bar to Single Holes. The results are automatically updated.
  4. To filter the results by hole size, click the bolt_find_options icon on the guide bar.

    • Select Options and enter a range, or
    • Click the icon to deselect all holes, select a reference hole in the modeling views, then select Find Larger, Find Smaller, or Find Similar from the drop-down list.
  5. To see where all of the holes are located, use the arrow keys on either the guide bar or your keyboard to pan your model from one hole to the next.
  6. To change which holes are selected individually:
    • Left-click a single hole to select it. The hole turns red.
    • Double-click a hole to chain select a group of aligned holes. The holes turn red.
    • Hold down the Command key and left-click to deselect a hole.
  7. To clear the selected holes and start over, click the icon to deselect all holes and then click the Find button on the guide bar.

Guide Bar Options

The Fasteners tool automatically finds and selects all holes that meet certain search criteria and highlights them in red. Use the guide bar to change the size and type of holes that are found and the type of fastener that will be created.

Click Find on the guide bar to find and select holes. The find operation is performed automatically when you first activate the tool, but you can click this button to redo the operation after making changes.
Click this icon on the guide bar to open a drop-down menu that allows you to find holes that are smaller, larger, or similar (±5%) in size to selected holes. Click the Options button to specify a size range for the diameter.

By default, the Fasteners tool automatically finds existing geometry in holes, hides it, and deactivates it so that it is not included in analysis or optimization calculations. Deselect Find Parts in Holes to disable this behavior, in which case you will need to delete the existing geometry manually.
By default, the tool finds Aligned Holes between neighboring parts. Click the button to switch to Single Holes instead.
Use the arrow keys on the guide bar or your keyboard to pan to the Previous or Next selected hole.
Click the Clear Selection button to deselect all holes.
Click this button to change the type of fastener that is created. If Auto is selected, the tool will automatically place nuts and bolts in through holes and screws in blind holes. If you select Nut and Bolt, fasteners will only be created in selected through holes, while selected blind holes will remain unfastened. Screws can be placed in both through holes and blind holes.
Click the Fasten All button to create fasteners of the selected type at all selected hole locations.
