Cheers ctbram

Thanks for that video, made it clear that most of the texts i found.

Will have a closer look when i get home later.

But now thinkig of this, what might be bugging maya is when i try to connect the first vertex, obviouslly the very first weld will leave 2 faces connected to 1 vertex, but that should be fixed when i weld he 2nd one, but maya keept shouting at me i was doing it wrong.

So perhaps it's becouse of the way i used to connect both subdivs? I used "attach surface" and then went into merging the vertexs (under polygon mode), just wondering if this is something i shouldn't do and it's causing all this.

Thanks anyway

Cheers,
DJ
