Did not catch what you mean about 0 deg, but part was created upright (fins were vertical) so I rotated it 90deg and placed on the build surface flat, is that what caused confusion in Cura ?
Cura 14.07 doesn't want to add support pillar, Im trying to print model from Thingiverse and in case 90deg overhangs It doesn't add support structure no matter what I do!! Slicer in same time add support properly.... But I want to make it work in Cura. I have single extruder setup Please help.
