Is there a way to fill the hole?

Sure, but you have to tell creo how to treat the inner volume.
See one possibility in the attached video.

THANKS! But it looks very distorted.

As written, it depends on what you "tell" creo to treat the inner volume.

See attached example (not finished).

My attempt.

Meh, lost my nerve near the end so if you can finish it cool.

Btw in Creo 3 we can fill holes when copying quilt but not that complex.

NX fill is real nice but in this case still gives less then perfect fill.

I was trying to something similar but ran into problems knowing what connected to what.

did you try the n sided patch option?

NX seems to be great doing that. Hope some day have tools like that in Creo.

Hope Creo 4.0 will give us a big surprise It's time to enhance Creo surface capability, What are you waiting for,PTC?

ok this is done in creo 2.0 student edition.....i have attached the step file also

But not tangent

consider this as the first step...since creo does not have a specific tool like in nx..

the good thing is..it took very less steps.

I have no excellent skills in ISDX module, but i reach a complete filling of entire surface with tangency continuity. I rebuild surfaces. Expecially near the hole, geometry was very poor. IDD isn't a perfect solution. I think that for guys of reverse enginering filling this hole is a joke. Sure it's not a 2 click work as in other software. I attach Creo2 and STEP file. There are little distorsions on my work, but i'm not a specialist.

Solidworks and NX both use Parasolid Kernel, maybe this is a limitation of Granite?

I don't think so,In advanced surface,Creo is weak compared with NX.Creo just provide IDD TOOL to fix input data(igs/step).It's a limited capabilities tool. From Proe to Creo ,do you see the advanced surface be enhanced?

I understand what you are getting at. People should not use Creo and should use NX or Solidworks because those programs are better in every way.

I see this thread as a way to show that some competitors of PTC are doing better productivity wise in this particular example.

I certainly don't doubt Creo more than I did before reading this thread.

One thing that I always tell my colleagues is if you only know one CAD software then you will become a toast one day.

Seeing how other software functions is interesting.

This case is a test of the ability of software to handle an unusual case where the geometry has been purposely damaged, but the user doesn't have enough information to recreate the part independently. A few people might have this happen as part of their work, but I would not want an expensive software development effort to fix a problem few people have when there are more universal enhancements to be made.**

If someone brought a metal mold with this complex curvy channel into a machine shop and then bored a big hole in the middle, what would the expectation be of repairing it?

This question boils down to - can software make a surface the user could not create on their own? I think it is interesting that other programs may be able to handle this problem, but it's not a problem Creo Parametric was designed to fix.

I note, for example, that Creo Parametric doesn't handle draped fabric very well and it doesn't have a Compositor for video or a non-linear video editor. All of these come free with Blender, but it is unlikely for PTC to build all these features into Creo Parametric.

It's good to know that using NX or Solidworks is an alternative when managing damaged surfaces. It's not good to complain as if there is no cost to developing a means to resolve this or that it is a software sales driver. Maybe there's a lot of demand for repairing overly-patched surfaces, but I think it is as much as there is repairing brutally damaged molds.

**Yet again, recent post about needing to control part color. First raised before Rev 14, and still not dealt with in a direct manner. The number of items that get different paint colors for different part numbers has got to be more than the number of defective geometry imports that need to be fixed in 2 steps or less, even if the desparation felt by users in the two groups isn't.
