I thus had to rotate in 2 steps. However this would lead to duplicate vertices on the seam - because if we apply "Coherence" (or "BooleanFragments") the geometrical entities will change... which will prevent the mesh extrusion to work. So the trick is:</div><div class=""><br class=""></div><div class="">- extrude in 2 parts</div><div class="">- mesh</div><div class="">- remove the duplicate vertices "by hand" with the "Coherence Mesh" command.</div><div class=""><br class=""></div><div class="">This is a bit ugly, but at least it works ;-)</div><div class=""><br class=""></div><div class="">Christophe</div><div class=""><br class=""><div><br class=""><blockquote type="cite" class=""><div class="">On 3 Jul 2018, at 09:20, Luca Verzeroli <<a href="mailto:luca.verzeroli@serioplast.com" class="">luca.verzeroli@serioplast.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div class="">Hi,<br class=""><br class="">I'm a researcher at the University of Bergamo (Italy).
