Fitting a 3D Shape into Another 3D Shape

You can use a new or existing 3D shape to fit into another 3D shape in a different solid functional set. It lets you define a protected area by using a solid functional set and adds a clearance.

You can use this capability to take into account in the designed 3D shape the space that will be occupied by another 3D shape in the same mechanism.

  1. Click Fitting in the Basic Features toolbar (Body Modifiers sub-toolbar)..

    The Fitting dialog box appears.





  2. Select Solid Functional Set.2 as the solid functional set that will perform the operation into Solid Functional Set.1.

  3. In the Clearance box, enter a value to define a clearance.

    The clearance defines a space around the tool body, based on a specified value, that extends the protected volume of the fitting by that value.

  4. Click Preview to see the result:



  5. If you want to define specific clearances between one or more faces and Solid Functional Set.1, click the Advanced tab.



  6. Select the face of interest, then, for instance, enter 4 as the distance value.



  7. Click Preview to see the result:



    Important: If you want to apply the same clearance to other faces, just select the faces, and select Apply distance to all selected faces check box.
    Tip: In case you want to remove:
    • A face from the selection: Select the face from the geometry.
    • All selected faces: Use the Clear Selections contextual command available from the Faces box.

  8. Click OK to confirm and create the fitting.

    Fitting.X is added to the specification tree in the Solid Functional Set.X node.



    The volume that is removed during the fitting operation is made a protected volume. No other entity in the same solid functional set can penetrate into the protected volume. However, entities from other solid functional sets can penetrate it.

    A fitting feature does not create walls in the shelled volume of the target solid functional set. If you want the fitting feature to inherit the shell thickness of the target solid functional set, thus creating walls of the same thickness, use the Push or Pull command.
