Hi Gianrico,

> Ok Michael, away from me the idea to ask fixing something for me!

Well, the true fix in this case would be for MoI's IGES reader to look at the group elements in the IGES file and only attempt to join surfaces from the same group.

I would like to fix this in the future, I have added it to my list of stuff to work on.


The other part that you are asking about, the disconnected object, is related to difficulties in processing the big pile of surfaces with coincident edges. Even if the area is not immediately in the same spot as the coincident edges, it is caused by side effects from those in other places of the model.


Are you able to use one of the methods above to get this model finished up properly?

Let me know you if you need any help finishing this, I could do one of those steps for you and send you the completed model if you are having difficulty finishing this up, just let me know.

Don't worry, Michael, I have no problem with this model.
It is only a test to understand what's happen.
I have other models with the same problem with completely different structure but for now I use a little trick:

1 - I look for the part that 'drive' the group
2 - Cycle thru select until it is the only selection (two or three clicks, strange but real)
3 - Click on 'separate' command'. Now the group is ungrouped but all the parts in the group (except the driver) are duplicate.
4 - Delete the duplicate parts.

Unlimited thanks
Gianrico

Hi Gianrico, I'm glad you have a solution!

I you have other sample files that have this same kind of behavior, can you please e-mail me those if possible? (moi@moi3d.com)

That way I will have more samples to test with when I get a chance to work on improving the IGES import.
