Problem is to make the alignment between them of numerous facets!

Maybe a trick is existing! :)

The best if of course to make from the begining directly a generative structure of "planar facets"
for avoid all this hand adjustment headache!

Who is not reasonable times consuming!

And here there are just 16 facets...in normal case that is more like 200 - 300! :)

Sorry the file with full alignment facets was not saved in 3dm format (so a good exercice! :)
only in SKP format! :(
