Creating a Lip

You can create lips on the divided bodies using Simple, Upper/Lower profile and Center profile methods.

Note: Depending on your role, you may not have access to this functionality.

This task shows you how to:

Create a Lip Using the Simple Method

You can create a lip using the Simple method.

  1. From the Manufacture section of the action bar, click Lip .

    The Lip dialog box appears.

  2. Set Height to define the height of the upper lip. The value must be greater than zero.
  3. Set Thickness to define the thickness of the lip. The value must be greater than zero.
  4. Set Mating angle which defines the vertical edge (defined by the height) of the outside of the lip. A negative value implies a snap fit.
  5. Set the Inside angle option: it defines the vertical edge (defined by the height) of the inside of the lip. A negative value implies a snap fit.
  6. Select an edge or a curve to define the path.
  7. Click OK.

Create a Lip with Different Upper and Lower Profiles

You can create a lip using the Upper/Lower profile method.

  1. Click Lip .
    The Lip dialog box appears.
  2. Set the Upper/Lower profile method.

    You are going to define one lip for two divided bodies Divide.x1 and another lip for Divide.x2 (highlighted feature).



    Look more closely at the profiles already sketched:



    Note: Profiles cannot be self-intersecting.
  3. Select a sketch as the upper profile.
  4. Select another sketch as the lower profile.


  5. Selecting Protected volume protects the volume of the lip area by preventing any additional material created by other features to be added to the lip.
  6. The lip path consists of edges or curve, planar or non-planar. All edges must be connected, and the profile plane must intersect a portion of the path. By default, all split edges constitute the path. Clear the option and select the edge to restrict the creation of the lips.


  7. Click OK to confirm the operation.

    Both lip features Upper Lip.x1 and Lower Lip.x2 are added to the tree. Each of them is located in a distinct Divide body.



  8. Hide Divide Body.x2 to make visualization easier. Lower Lip is created only on the selected edge and the protected area appears in red.


    Looking more closely, the shape looks like this:



  9. Show Divide Body.x2 and hide Divide Body.x3 to see the second lip.


Create a Lip with a Single Profile

You can create a lip using the Center profile method.

  1. To perform this scenario, delete Divide Body.x3 to obtain only one divide feature.
  2. Select Divide Body.x2 in the tree and set it to Define In Work Object.
  3. Click Lip .
  4. Select the Center profile method.
  5. Select a sketch as the center profile.


    By default, the Protected volume option is not selected. This protects the volume of the lip area by preventing any additional material created by other features to be added to the lip.

  6. The lip path consists of edges or curve, planar or non-planar. By default, all split edges constitute the path.
  7. Click OK to confirm the operation.


    Looking more closely, the shape traces the center profile sketch.
