Simple sounding question... i have a surface with a hole in it that I want to fill in. Boundary blend doesn't seem to work. How do I go about filling in the hole with a surface?

Select the face (so that it is highlighted pink in shaded mode)



CTRL-C (copy)

CTRL-V (paste)



In the dashboard look for "options"



Under that you will see "exclude surfs and fill holes" - click that radio
button.



Mouse over the edge of the hole you want to fill and click it when it
highlights.



MMB for done.



Hope this helps.

    This is by far the best suggestion in the thread.  Its quick and easy.  Look no further.

    It's good to know about the (hidden) option to fill the holes when copying and pasting quilts, but I do think that the remove function seems more appropriate.  It was mentioned in this old thread that the function doesn't work on "edges", but seems Creo is more capable now.

    Hole removal example illustrated in Creo 4:

      RE: Boundary Blend


      Old method: Create a datum curve at the 2 hole vertices, create 2 blended surfaces from this, then merge these surfs with the original surface and end up with one contiguous surface...Just saying.

      Boundary blend won't work for round holes. Even though the hole is made
      up of two edges, the ends of the edges are tangent and the blending
      becomes undefined. You cannot boundary blend features that are tangent
      on the ends of the edges.

      Instead, select the surface and copy-paste. During pasting there
      should be an option to fill in holes and exclude patches (or similar).
      Select the hole boundary to fill-in and all should work OK.

      a) Create a datum curve "diameter" using the 2 vertices of the hole feature. (Where the half-circles meet)


      b) Select this datum curve "dia" and one side of the hole. (I.e. half-circle)


      c) You can create a blend surfae from these 2 entities.


      d) Repeat for the other half.


      Please see attached figure.


      Hope this helps.

      What happens to the original surface? Do you delete it? And then merge
      the new surface with the existing quilt?

      Why doesn't it work the intuitive way? Select the edge and press
      Delete?

      Sometimes PTC has a way of having great functionality... but hiding it
      behind mysterious methods and/or way too many clicks.

      Because we don't create edges, we create features. Delete the feature
      and the hole disappears. But that may not be what the OP wants.

      You can use the REMOVE feature but not on the edge, rather on the
      surface of the hole.

      The hole surface looks planar. If so, a FILL surface should work.

      Or suppressing the hole...

      Or INSERT MODE before the hole, copy the surface, resume the hole...

      Or do what Nathan said...

      Or REMOVE the hole...

      (In reply to Asselman's reply via RUi's reply.)

      It's not in WF3; maybe WF5. to chose the two curves and select Edit
      Fill? It seems like that worked some time.

      Selecting the edge and pressing Delete is not as intuitive as one might
      think. Since the surface is bounded by the curves, eliminating one or
      more of those curves should delete the surface that depends on it/them,
      leaving only the remaining curves.

      A good way to reason this through is to think of Pro/E, Creo as a
      procedural modeler. You're not simply editing a model - you are creating
      a procedure to create the model you want. The ability to edit the
      procedure and have a model be the end result is what makes Pro/E, Creo
      the software that it is. It doesn't have a way to delete part of an
      existing feature yet, in the way that a straight B-Rep modeler does. In
      the B-Rep modeler, of course, gone-is-gone. The main place Proe/E, Creo
      has that does handle things like this is the Data Import Doctor, which
      operates on non-procedural imported geometry. Everywhere else, you don't
      really delete a feature, you delete the procedure that creates a
      feature. That's how suppress works, just less permanent than delete.

      Of the methods mentioned, the copy and paste method allows multiple
      holes to be eliminated in one step, while the add-curve and blend takes
      three or more steps, depending on the desire to merge the new surfaces
      with the old ones. I know that Fill works when you create a sketch, but
      will need to be merged to create a single surface.

      The original surface likely has to stay as that is what the copy/paste
      procedure is based on. It's why you won't be asked where it goes as it
      is placed exactly as the original was placed.

      Using the Import Data Doctor on imported geometry, you can simply select one inner edge and hit Delete and the full inner contour is removed.
      So PTC has the functionality, but not always where you want it.
      Maybe the new Flexible Modeling Option available with Creo 2.0 has this capability.

      Extrude > surface > cut at the extents of the hole in an appropriate 'square' boundary, back fill with boundary blend with tan boundary conditions.
