I think it's leaving too much past editing data in the file.ДЄnyone got any ideas what can be done about this? Is Microsoft Development fixing it? My theory is that 3D Builder isn't cleaning up after itself. At times there wasn't much difference between the duplicates, so it was impossible to sort out which was the final copy. That is until I realized that some of the duplicates represented small adjustments, etc. I thought I could go through the list, check each model and delete the objects I didn't need. There's also a couple of pieces of objects as well. The majority of this list are duplicate models from different edits. It's hard to see, but the 2 objects I pointed out are actually duplicates. The list of objects in the Object Browser window is a list of all the separate models in the file. Please notice the 2 objects at the near part of the grid. The box with the red bubble represents the print area of my printer. In Meshmixer, I saw what kind of a mess there really was: So, then I opened the file up in Meshmixer because the Microsoft site 3D Tools couldn't fix it. They also have massive boundaries around them. This is the reason the other models aren't touching the bed. 3D Builder introduced a huge amount of empty space. Those are the actual boundaries of the model. Please notice the white lines extending from the striped model. These models are only supposed to take up an area approximately 150mm x 200mm x 25mm. If you notice, 2 of the objects aren't sitting on the bed and the striped pattern indicates that that model won't completely fit on the bed. I would have used 3D Builder to print them, but it doesn't support any of the printers people actually use. Just in case you're not aware of the problem, here's how it works. Does Microsoft have a solution for the corruption introduced into edited models by 3D Builder?
