I found a bug in SW2015, but reporting a bug is only for those with an "Active subscription." I am just a user. My employer licenses SW from a reseller. I have no idea who in that chain is allowed to post bugs.
Here is the problem: SW2015 adds in .amf export. I designed a part in mm, chose mm from the options when saving, and made a AMF file.
Slic3r, the slicing software for the repraps, only imports STLs and AMFs as mm, but the AMF is ~100x smaller than designed; an obvious unit error. The same part as STL imports at the correct size.
AMF is a huge step forward for 3D printing, and I thank 3DS for finally giving me a tool to generate an AMF. The slicing support has been in place for years.
