Hellooo…
thanks Milos and Martinb,
yes this is what I did, and it works… BUT with a couple tests, I get several components…
let;s say I have 250 cams… then 120 cams in 1 component and 130 in another component. And these 2 components, while being correctly aligned on each component, are not aligned between them…
How do I align these two components…?
