selected by default.3. Specify the draft direction by selecting one of the following:
◦ One Sided—The draft is created only on one side of the reference curve.
◦ Two Sided—The draft is created on both sides of the reference curve.
4. Specify the pull direction.
5. Click the References tab, click 
under Draft Line Selection, and select the reference curve. The reference curve must lie outside the reference part geometry.
