Computing Interferences

Compute Interferences lets you compute an interference, and save it under the active markup.

  1. In the Context tab,
    1. Define the context of the simulation.

      By default, the context of the review is selected as a context for simulation.

    2. Select the Append Intermediate Representation check box to include intermediate representations to the interference computation.
    3. Select the Compute Between Intermediate Representation check box to identify interferences that exist between representations under the same product.
  2. Define groups inside the simulation context.
    1. From the list, select one of the following:

      • Inside groups: to compute interferences between the elements of a group. You can select one or more groups. However, interferences are computed only between the objects of the same group.
      • Groups against groups: to compute interferences between the elements of different groups. Interferences are computed between all parts of one group and all parts of other groups.
      • Groups against context: to compute interferences between the selected elements in a group, and the remaining elements in the context. Interferences are computed between defined groups against the context.

    2. Click Add new group to create a group.
    3. Add the required products in the group.

      • Click Add the selected products to this group : to add products to the group. Select products or parts in the 3D area or in the tree to add them to the group. The already added products in the group are highlighted in the 3D area and in the tree. You can cancel the selection of any product by selecting the product again.
      • Click Remove the selected products from the group : to remove selected products from the group.
      • Click Delete this group : to delete the selected group.

  3. In the Specifications tab, select the options for standard, and engineering connection specification.
    1. In the Standard Specification area:

      • Clash and Contact: Computes clashes and contacts.
      • Clearance: Computes the clearances lower than the minimum clearance value defined in the Clearance box.

    2. For light interference simulation, select the Activate check box and then the required specifications under the Engineering connection specification area:

      • Check No Clash: Identifies only clashes.
      • Check Contact: Identifies clashes and clearances.
      • Check Clearance: Identifies clashes, contacts and clearances with distance less than the specified minimum value of the clearance.
      • No Check: Avoids computation for the interferences with specifications set as No Check in the Engineering Connection Definition dialog box.

    3. Select the following check boxes under Compute quantifier area to compute the quantifiers and display their values in the Quantifier column of the interference simulation list:

      • Minimum Distance: Computes and stores the minimal clearance distance. This check box is available when you select the Clearance check box.
      • Penetration Vector: Computes and stores the penetration vector value when a clash is identified.

  4. Click OK.
  5. To check the interference simulation results, double-click the Interference results node in the tree.
