Push a Body

You can push a selected body into another body and carry out various operations (like filleting and removing the unnecessary faces) on it.

  1. From the Create section of the action bar, click Cutout or Push .

    The Cutout.x dialog box appears.

  2. Select External Shape as the shape definition.
    The Push.x dialog box appears.
  3. Select the pushing body in the Tool body box.
  4. In the Clearance box, enter the clearance value.

    Clearance is the protected volume around the pushed feature that separates it from solid functional set.



  5. Under Wall:
    1. From the Type list, select Enter Thickness.
    2. In the Thickness box, enter the thickness value.
    Note: The walls produced by the Push feature are defined by one of the two options available from the Type list:
    • Use body thickness: The push wall thickness is that of the active shelled body thickness.
    • Enter thickness: Enter the value you want. After this option is selected, the Thickness box becomes available. Wall thickness values can only by positive values.
    • The Constant wall thickness check box
  6. To add fillets, click the Fillet tab.
    1. From the Intersection fillet list, select the following check boxes to create fillets at the required intersections:

      • Intersection with Core/Cavity
      • Intersection with Core
      • Intersection with Cavity

    2. Select the Fillet radius check box to create fillet by adding material to the feature.
    3. Select the Round radius check box to create fillet by removing material from the feature.
    4. Select the Preserve shell thickness check box to maintain the thickness at fillets.
  7. Click OK.
    The push feature is created. Push.X is added to the tree under the Solid Functional Set.X node.

  8. In the Faces to remove box under Control, select the faces to be removed, if any.



    Tip: If you want to remove:
    • A face from the selection: Select the face from the geometry.
    • All selected faces: Right-click the Faces box and select Clear Selections.
    Important: By selecting faces in the Faces to remove box under Openings, the walls facing to the selected face will be removed. This feature is useful for the vent shapes. The clearance option on selected faces will be compatible with the selection of faces to remove.
  9. Click OK.
    The push feature is edited.

Define Additional Clearances

You can apply clearance value between the pushing body and the existing body.

The clearance is the protected volume around the pushing body that separates it from solid functional set (see scenario above).

If you want to define other clearances between specific faces and the solid functional set:

  1. Select the Other clearance faces tab.
  2. Select the faces of interest and click .
  3. In the table that appears, specify the distance values for all the selected faces.
    Additional clearances are applied.



If you want to apply the same clearance to other faces, select the faces and select Apply distance to all selected faces check box.

Note: To clear selection from a face, select the face again. To clear all selections, right-click the Faces box and select Clear Selections.
