Checking Interferences

You can check intersections and interferences on meshed 2D geometry (surface elements). The tool checks for standard geometric intersections and indicates interference when the elements are more than a specified clearance distance from the associated geometry. The clearance distance allows you to account for the real thickness of the geometry.

Before you begin: Surface meshes must exist.

  1. From the Check section of the action bar, click Interferences .
    The Interferences dialog box appears.
  2. In the Clearance box, enter a value beyond which you want to check for interference.

    If the clearance value is equal to zero, only intersections are checked. If the clearance value is greater than zero, intersections and interferences are checked.

    Important: The maximum value of clearance must be smaller than the mesh size.

  3. Optional: To specify the meshes to check, click Selection in the Mesh parts list, click , and select the desired meshes using the dialog box that appears.

    The Mesh parts list is not shown if the model contains only one mesh.

  4. Select the Thickness from sections check box to include the thickness of sections in accounting for interference.
    1. Enter a Default thickness to use for sections whose thickness is undefined.
  5. To dynamically visualize interferences while you are modifying the mesh, select Dynamic check.

    Dynamic checking is not available if you included Thickness from sections.

    When this option is active, the interference is checked each time you modify the mesh.
  6. To focus on and scan the interference areas, select the Autofocus check box, and use the browse buttons.

    Tip: You can use the clipping box tool to visualize the interference areas while you browse them. For more information, see Using the Clipping Box.

  7. Click Apply to perform the interference check, or click Close to exit the action.
