Mounting Boss

• Select a face . Select a planar or non-planar face on which to place the mounting boss. The software creates a point (where you select the face) in a 3D sketch.
  
  To position the mounting boss, do one of the following:

• • Edit the 3D sketch, then dimension the point.

  • To place the mounting boss at an exact predefined location, before or after you create the boss, create a sketch with a point at the desired location, then select that point for Select a face .

You cannot edit the point during feature creation.

• Select Direction (non-planar faces only). Set a direction for the boss. If not specified, the boss is placed normal to the face at the selected point. Click Reverse Direction if necessary.

• Select circular edge (optional). Select a circular edge to position the center axis of the  mounting boss.

The projected center of the circular edge must intersect the face where the mounting boss is positioned.

• Mating face . Select a face to which you mate the top of the boss. The boss height is automatically calculated. If you change the height of the mating face, the boss height changes too.
  
  You can mate the boss to a face that does not contact the boss. For example, the mating face and the boss can be side-by-side.
