Hello friends !

I have two independent surfaces.

1st: was build with a normal loft from two ep-curves
2nd: was build with birail 2

If I want to attach the surfaces, the surfaces disappear - yeah, both surfaces suddenly disappear.

hmm, have no clue what is wrong.

I´ve tried to delete the history from both surfaces, but there was no difference. Both surfaces disappear after attaching.

What can I do ?

thx for every littel help,
bernhard
