Multiple Objects in 1 STL

  • Are you ever going to fix this? Over 2 years ago I asked about this, and was put on the list to take care of. But it still is not fixed in the latest release. If there are multiple object in 1 file/STL it automatically does a screwed up XOR like thing. I am still having to separate each object into separate files, load them, and then align them.

    There was a fix for this sometime last year. But like many bug fixes it only addressed cases we knew about.

    Can you please submit an issue to GitHub with the model and a screenshot?

    We would love to investigate and fix we're issues like this.

    Copying the GitHub response here.

    This has lots of self intersecting geometry which can have an undefined result. It is hard for the algorithm to find a solution. I tried to repair it with NetFad and it gave an error. I would recommend you try to repair it with another mesh tool (possibly meshmixer or meshlab. Or if you can re-model it.

    I also tried this online tool and it produced as a result.

    Here is a screenshot of the fixed mesh.
    As you can see, it could not detect the complete whole correctly.

    We will keep this as a test model (if its ok) to try and improve the algorithm, but it seems like this may not be fixable.

  • Odd, my response didn't get posted.

    The thing to do is just separate the models. If I manually separate the models and load them individually, then align them it prints perfect.
