Fill a Gap

Advanced Face Modeling Package

General

  • You can fill a gap in a model with a tangential face. A gap is a face missing from the model.
  • This functionality requires the Advanced Face Modeling Functions add-on option.
  • This function is required when you import from another CAD system a model that is missing a face or faces, or from which you want to replace an invalid face with a new tangential face.
    • It is usually not possible to perform all the normal modeling operations on such a model until the missing faces have been added and it has been formed into a volume.
  • You can also use this function when you have removed a face (invalid or a planar surface, for example) from a part model and want to replace that face with a new tangential face.
  • If no tangential requirements are set for the face to be added, you can try to create a volume with the To Volume function.

  • In the figure, the (red) plane surface has been replaced by a tangential face.
