I have an object that I want to quadruple in size (double up and down, double left and right). I know how to split it into 4, but then I have to center each quarter and then double its size to print. But how I can I exactly do this so the 4 pieces fit perfectly together? Is there a center of the object that can be placed at the center of the bed?
Thanks.
Can you explain more about what you are trying to do? Is there some reason you can’t just scale the object like this?
There’s a lot of detail and when I zoomed in many times so it would fit in bambu, got some weird domes in some objects, There is about 35% that can b removed.
I figured scaling too far messes tins up. it’s about 0.001 scale is what I seem to have to go.
Can you upload the model or at least some pictures so we can see what you’re talking about? If you scale that large and the details look bad, it’s likely because the model wasn’t high enough resolution. Things can look sharp when they’re small but blow that up 4x and all the imperfections are now front and center. Or are you seeing something different than that?
The model is massive and I need to shrink it by 1000 in Fusion to fit on the Bambu bed. Did that in Fusion. I guess zooming in that far could cause issues? The details are in the huge original 1, and would be less sharp. Then I uploaded to Bambu, I saw some weird shapes. Not simple rectangular building roofs. So zooming in that far, to find the smallest areas, accuracy gets hurt?
Will try to upload.
Your problem is the model, not how to print it 
Keep in mind that the number thing is having a solid and flawless model.
With that the size does not matter as you can scale it any way you like.
If that fails and produces artefacts or worse it just means the model is bad and has errors.
If you can scale the model to size in Fusion make sure to have it checked and if doubt to also check how complex it is.
For example a STL file of 100 or more mb while only being 10X10X10 in outlined volume is total overkill in almost all cases…
It is also prone to produce manifold errors or geometry issues…
So no data is lost when cutting and changing size, etc. There’s no interpolation going on? Combining or smoothing out?
So, no, it’s all just the initial model?
No, yes - depending on how you interpret your question.
Sizing does not change things, cutting a model always does and in most cases will result in manifold problems if the model is a complex one.
A cube, cone or such is no issue, a 3D scan of your head will be…
The problem is not the cutting but how it is done in Studio.
If you need to cut the model into pieces then scale it to the required size and do it in the CAD program you used to create/modify it.
There you have the control and also a far more capable engine.
Studio is mainly a slicer - never forget that
