Hello, I noticed that the rafts created by s3d are simply not compatible with ninjaflex and maybe other filaments that wont appreciate to be pushed to fast. on my FFC I have no big issues with ninjaflex except for the raft. I'm then forced to import a raft myself, which consists of a simple 1mm high...
+1 to the possibility to select a face and lay it flat on it. That would address more than 75% of the situations where you would normaly have to go back to a 3d soft, import the stl, arange it (that could take time too) and re-export it.
