Offset Faces Error

Augmented126 — Sun, 14 Apr 2019 18:06:18 GMT

I have a problem with Offset Faces, it's giving me a error, i have a video for more information.

Thanks for taking your time to help me.

PS: It my first time posting on any form sorry if i didn't post it right.

@Augmented126 , it's hard to say without the model - can you share it here? The one thing I would try is to do both faces in one Offset, rather than two separate Offsets. It could just be that this offset will fail, but the geometry looks OK to me.

@jeff_strater Hi ,trying to do both offsets didn't work either, i will give you the file maybe you find something.

Thanks for the help.

Thanks, @Augmented126 for the model. I see the same thing that you do. Let me work with the modeling kernel guys and see if they can help out. No good news for now...

@Augmented126 - I heard back from the modeling kernel guys, and the answer is something I should have seen from the beginning... I can't take credit for this, but, here it is. The problem can be illustrated by looking at the edges of the bottom of the faces of this body. These are circular arcs. You can see that if I offset one of those arcs, the other arc will still intersect the offset:

However, if you offset both arcs, they no longer intersect:

The same analogy applies to the surfaces themselves. If we offset both, they will no longer intersect, which is why the operation fails.

Hope this makes sense...

Thank for the help, but i don't know how to resolve this, i am trying to close the gap and after that combine the objects.
In the video i have o solution but it is a bad one, can you tell me what i need to do to make this work, i realy apricete the help you gived me so far, thanks a lot.

@thebrigand1 - there probably is a way to patch up this geometry, probably using Loft. But, as we saw, offset just is not going to work. So, I stepped back and looked at what you were doing - you were cutting the cube up using a narrow groove, then trying to repair the damage. Instead, if you create those as surfaces, you can use Boundary Fill to get what I think is the result you were looking for. If not, I apologize:
