I think that components are explained in the offline help.
Either you put only a limited number of images into a new project, align them and then export them (workflow - export - registration). Make sure the right component is selected. If you only want a part of the aligned cameras, select them beforehand and only the selected ones will be exported.
Once you have created several components, import them (workflow - import - component) into a new project.
In the alignment settings set “align only components” to true and hit the alignment button.
If everything has been done properly it should then create one big component with all cameras.
Of course, there needs to be enough overlap between the individual components…
Hi Götz,
coming back to you a bit later but meanwhile i tryed your suggestion and it really helped.
I can still find some “double” surfaces but the offset of them is much smaller - can be also a problem of the shooting process. But the result is good 
Thanks again.
