Default Bottom Up Approach Merge Vertices at the end

Hello everybody,

I have the following question:

- I have meshed a geometry where I have chosen a bottom up approach

- Due to the bottom up approach I now need to merge the two ends of the block to "close" them (see first attached picture)

- Then with the function merge vertices I connect the two ends. (see second Picture). The result from that can be seen in the third picture

- My problem is that icem doesnīt recognize one of the merged edges as an internal edge (light blue color). Therefore I get a strange Mesh at this point. See fourth attached picture to see what I mean

Does anybody know where the problem is?

Thanks a lot for your answer and have a nice day!

Hi pamstad,

this may be an artifact from the merging.

Delete the association on the edge to revert it to an internal edge.

Hopefully, all the invisible edges in your blocking are not going to interfere in the further process...

Best,
Sebastian

Hi Sebastian,

thans a lot for your answer!

I donīt get what you mean: You said I should delete the association on the edge to revert it to an internal edge. But on the edge we are talking about (the one marked in picture 4) there is no association? What do I understand wrong?


Thanks and have a nice day

Patrick

Hi Patrick,

the color black of the edge indicates that the edge projects the "edge to
surface", the closest one. So there is an association. However, this one was likely set automatically. It's an artifact of the face being infact a boundary face before.

Disassociating the edge will make it an internal edge again.
You'll find it in the tap blocking under:
Associate > Disassociate from Geometry: select that stray edge for disassociation and apply.

Best,
Sebastian
