I'm new to S3D and may be missing a setting. But in reading on the site I am not finding an answer. I am trying to print a part that is made up with 4 pieces. Two of the four part recess into the other two forming a solid part. Cura will slice it as a solid, but S3D is treating it like four pieces. If my photos stick it will be evident as to what I'm trying to do. The printed part came from Cura. I tried turning on Gap Fill to no avail.
Would appreciate some guidance. Thanks in advance.
