Changing edge direction
 

Hi All!

Does anybody know how to change the direction of an edge (at blocking meshing method)? The direction of edges can be seen when I turn on the bunching on edges or just when I change edge params. I know how to change the direction of a curve, but is there similar command (or sth) that I can do with edges? Actually, a few of my edges are not associated with curves just with surfaces.
I faced this problem when wanted to link buching from other edges to some edges but this problem occured:

'internal error in copy_linked

A minor internal error has occurred.
You may continue to work but if problems arise they may be related to this error.
Try using the check/fix function to fix the problem
The following message was designed to aid developers fix the problem:

can't unlink counts at this point'

I realized that some edges point to the opposite direction than the edge from which I want to copy distribution with link bunching option, so that caused the problem. But still I can not think about other solution than to change edge direction but I do not know how to do it! So anybody please help! Thank You in advance!

Hello,

You can avoid the error message by using the "reverse link" option when you are link bunching the edges.

Assume your large parallel edge is running from left to right.
You have several smaller, connected edges, that are parallel to this large edge.
Assume the most left edge of these is running right to left.
To link bunch, you select the large edge, than link bunch the most left one of the smaller parallel edges. After selecting this edge press Reverse Link button and press apply.
This will link bunch your edges correctly without the error appearing.

Good luck!

Link Bunching
 

Nope, there is no way to change edge direction (that I know of, and I think I know all the options ;) )

Anorky is right to suggest "reverse" if you are trying to copy edge parameters to an edge or link the initial spacing, but I think you are trying to use the "link bunching" command.

This is one of the trickiest commands to use because you need to select the low side of the target edge... You can't select any of the three edges.

For example, if on the one side, we have one long edge and we want to link bunching to make the mesh parallel with three short edges, you must pick the lowest edge (index wise) of the three as the source. This should be the edge that has the same side one index as the edge you are linking.

I don't think this command properly supports a situation where you would have the index in different directions on either side of the mapping (perhaps you could submit the model for testing). If that is the case, you may need to extend split and avoid the need for linked bunching.

One last thought... If the mesh looks fine, you can ignore those minor errors. They don't really stop you, and often they are only FYI.
