Additionally each slice of each part is in it's own layer.\r\n\r\n### Reproduce\r\nWe take this example from microsoft's 3mf repository: [Train Engine.zip](https://github.com/alexrj/Slic3r/files/1737849/Train.Engine.zip)\r\nwhich looks like this: \r\n![3d train](https://user-images.githubusercontent.com/29820012/36392179-5ae8200c-15aa-11e8-8e7f-35dbdbd1ad35.JPG)\r\nSlicing it via File -> Slice to SVG... produces the following SVG: [Train Engine_svg.zip](https://github.com/alexrj/Slic3r/files/1737867/Train.Engine_svg.zip)\r\nHere are the first 9  layers to illustrate what happens:\r\n![slices](https://user-images.githubusercontent.com/29820012/36392623-74f82062-15ac-11e8-93ce-7b8117aa79db.jpg)\r\n(read from left to right, top to bottom)\r\n\r\nI don't really mind the fact that each object is in a separate layer, it even makes it a bit easier for my application. But they should be positioned correctly on the platform\r\n\r\nI noticed that this is handled differenty when slicing through Window -> DLP Projector -> Export SVG.\r\nLikely because this is done in SLAPrint.cpp and not in print.pm like when going via File -> Slice to SVG.\r\n\r\nTherefore I will try to go through the Window option for now and leave this Bugreport here in case other people have similar issues.\r\n\r\n\r\n\r\n"},"comment":{"url":"https://api.github.com/repos/alexrj/Slic3r/issues/comments/368270776","html_url":"https://github.com/alexrj/Slic3r/issues/4310#issuecomment-368270776","issue_url":"https://api.github.com/repos/alexrj/Slic3r/issues/4310","id":368270776,"user":{"login":"lordofhyphens","id":31754,"avatar_url":"https://avatars0.githubusercontent.com/u/31754?v=4","gravatar_id":"","url":"https://api.github.com/users/lordofhyphens","html_url":"https://github.com/lordofhyphens","followers_url":"https://api.github.com/users/lordofhyphens/followers","following_url":"https://api.github.com/users/lordofhyphens/following{/other_user}","gists_url":"https://api.github.com/users/lordofhyphens/gists{/gist_id}","starred_url":"https://api.github.com/users/lordofhyphens/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/lordofhyphens/subscriptions","organizations_url":"https://api.github.com/users/lordofhyphens/orgs","repos_url":"https://api.github.com/users/lordofhyphens/repos","events_url":"https://api.github.com/users/lordofhyphens/events{/privacy}","received_events_url":"https://api.github.com/users/lordofhyphens/received_events","type":"User","site_admin":false},"created_at":"2018-02-25T00:09:55Z","updated_at":"2018-02-25T00:09:55Z","author_association":"COLLABORATOR","body":"@Samir55 any ideas if there is anything weird going on with 3mf itself?"}}
