A new try (4/5) :)
Seems impossible with this design of letters :D (same forms file above)
Else funny to do :)

Program just crash one time on "Bolean union" of a complex object entielrely "auto trimed" ---> Bolean union
(maybe I have no right to do that? :)

> Boolean union crash.

Can you look for a moi_report1.zip file inside your \Program files\MoI folder, and if you've got one, please e-mail it to me at moi@moi3d.com ? That crash report file has some information in it which might help me analyze the crash.

For surfaces that have been trimmed to touch edge-to-edge, you should generally try to use Join to create a single object out of them, not boolean union - use boolean union when there are some parts that intersect with each other.
