> ## Interference Checks

> You can check for spatial interference of any two model parts.

> ## Interference Check Options

> With the Interference Checking option, you can perform different interference checks. These checks are:

> Check | Description
> --- | ---
> All Against All | Check for interference of any of the parts in the model.
> Set Against the Rest | Check where a model part or set of model parts interfere with other model parts.
> Set Against Itself | Check where a model part or set of model parts interfere with itself.
> Set 1 Against Set 2 | Check where a model part or set of model parts interfere with another model part or set of model parts.

> ## Performing an Interference Check

> 1. From the Analysis menu, select Check for Interference.

> The Interference Checking dialog box appears.

> 2. From the Scope options, select the type of interference check that you want to perform.

> See Interference Check Options

> 3. If you selected Set Against the Rest or Set Against Itself, select one or more model parts on the model or from the Model Tree.

> Note: To select more than one model part, press the Shift or Control key while selecting.

> The model parts appear in the Selected Set list and are highlighted on the model and in the Model Tree.

> Note: To clear the last set of selected model parts, click Clear.

> 4. If you selected Set 1 Against Set 2, click the Set 1 arrow , then select one or more model parts on the model or from the Model Tree.

> Note: To clear a selected part, press the Control key and click on the part on the model. To clear the last set of selected model parts, click Clear.

> Click the Set 2 arrow then select one or more model parts on the model or from the Model Tree.

> The model parts appear in the Set 2 list and are highlighted in a different color on the model and in the Model Tree.

> 5. In the Minimum Clearance Distance field, enter a distance. The default value is 0.

> Note: Adding a minimum clearance distance not only checks if the two model parts interfere, but also checks if they are located within a set minimum distance.

> 6. From the Units list, select the unit for the clearance distance.
> 7. To configure the interference check results, click Options.

> The Options dialog box appears.

> See Interference Check Results Options

> 8. Click Compute in the Interference Checking dialog box.

> Note: The Compute button changes to Stop. To stop the Interference Checking process at any point, click Stop

> Note: Section plane is not taken into consideration when computing an interface check.

> When the process is complete, all the instances of interfering pairs appear in the Results list. The number of interfering pairs found appears in the Description box.

> Note: To view a pair’s interference information, click the corresponding Results line. The information appears in the Description box and AutoVue zooms into the interfering area.

> 9. To save the results, click Export.

> The Export Results dialog box appears.

> 10. Specify the file name and the directory where you want to save the file.
