CreateDeleteEdgeBuilder failing to create surface

[esikoglu]

We have pre-existing code that creates surfaces over a cut-out. This code is now failing with the message "The remaining edges cannot adapt to close the area left by deleting the selected edges."
The code uses Part.Features.CreateDeleteEdgeBuilder(null) with Part.ScRuleFactory.CreateRuleEdgeDumb(TopEdges.ToArray()) where TopEdges are a selection of edges around the top of the cut-out.

We can't find any documentation on the methods we are using and would be grateful for any clues to help us diagnose the problem.

It sounds like you want to delete all the edges of a cutout to delete a hole in a face? The message seems to indicate that one or more edges remain and NX can't close up the hole and keep those edges. Make sure that you have given the builder all of the correct edges to work with.

We believe that we have the correct edges since there are some holes that the software is working. I checked the initial persistence data for each hole. Everything seems fine until this Part.Features.CreateDeleteEdgeBuilder(null) part, and I am trying to understand what it does.
The idea is to create a patch using the edge values after deleting and calculate the center of the cut-out and put a datum axis from top to bottom to create a toolpath.
Sorry for the delay,
Regards

How do I check and be sure that I have the correct edges on the builder, is there a way to do it?

Once you have collected the edges, call .Highlight() on each one and exit the journal code before any other processing takes place. This will visually show you which edges the code is working with.

Are you dealing with a solid body? If so, deleting the hole faces would probably be a more robust way to fill it in.

I am dealing with turbine blade cooling fan shapes and holes, selecting the features manually ->Top face, edges, hole faces etc. I will try the .Highlight() asap thank you so much

I fixed the problem, thank you so much!! I added these lines right after I collect the edges and problem is solved UFSession ufs = UFSession.GetUFSession(); ufs.UiOnt.Refresh();

Cheers
