To Analyze Interference Among Components

Using the information from the analysis, you can modify components to eliminate the interference.

What's New: 2024.2

  1. On the ribbon, click Inspect tab Interference panel Analyze Interference .
  2. In the Interference Analysis dialog box, click Define Set #1, and then select the first component or group of components to analyze in the graphics window or browser.
Tip: If you want to check all components for interference, use a crossing window to add all components to Set # 1 and then click OK to analyze.
  1. Click Define Set #2, and then select the second component or group of components to analyze.
  2. Select Treat subassemblies as components to treat sub-assemblies as single components and ignore the interferences within the sub-assemblies.
  3. Unselect Use precise thread analysis to exclude precise analysis of full threads from start to the end of the thread.
  4. Click OK to check for interference.
Tip: By double clicking on a resultant interference, you can graphically focus on an individual interference region by zooming into a specified collision.

  1. If interference is detected, the Interference Dialog box dialog box displays the following:

    • The number of interferences detected and their total volume, and additional information about each interference. Double-click an entry in the list to zoom to the interference.

    • Options to filter out the following interference types so that you can focus your attention on the information you need to analyze:

      • General: Interferences that do not belong to any of the types below.

      • Threads: Interference between 2 components, one of which is threaded.

        If found, Matching Threads displays as an additional filter.

      • Non-threaded Content Center parts: Interferences between 2 components one of which is from Content Center.

      • AnyCAD reference components: Interferences within the AnyCAD reference component itself.

    • Detailed information about the 4 types of mismatched thread interferences. Hover over the information tooltip to display the type of interference.

      • Threaded components are misaligned.

      • Thread designation doesn't match, including nominal diameter, pitch .

      • Left/Right hand doesn't match.

      • Thread depth mismatch indicates the external thread length and the internal thread depth do not satisfy the minimum thread engagement.

        For example, interference is reported when the length of a component's external thread is shorter than the depth of the internal thread. The following illustration represents another example where minimum thread engagement is not met.

    Note: The first set of numbers in the tooltip indicate Internal thread value. The second set indicate the External thread value.

-    Ignore and Un-ignore options. You can:

    -    Right-click an item and select to ignore the selected volume or ignore all interference volumes less than a selected value.
    -    Select or deselect the Ignored filter to show or hide the ignored interferences in the list.

        Note: An ignored interference is displayed with a cross line.

    -    Right-click an ignored interference and select to Un-ignore the selected item, or Un-ignore all.

-    Options to copy the values to the clipboard and print the list.

    Note: The interference type is included in a new column called Note when you copy ![](../../images/jdi_r3_interference_excelcopy.png) a thread interference value into Excel.
