Repairing problems
You can use 3D curve and surface creation commands to create shapes that would be difficult to build with standard features.
For example:
To remove an existing problem face from a body, use the Unsew command (Home tab→Feature group).
To combine faces or add faces to a body, use the Sew (Feature group) or Patch (Feature group) commands.
After each repair, check for free edges using the Sheet Boundaries option in the Examine Geometry dialog box.
