… cube for instance. I did do a search for my question, but couldn’t find any info.
I know that Bambu Studio has some basic design options, like adding and doing nice stuff with cubes, circles and so on. But what if I would like to create chamfers and or rounded corners on let’s say a cube, is that possible within Bambu Studio, or should I create that in ‘real’ 3D design software?
You can do cuts on your model in BS. But you’re limited to a flat plane.
You could in theory trim the corners of your cube with the cut tool to make a chamfer.
Use the “Cut tool” and angle your cutting plane to the desired chamfer.
Fillets (round corners) would be difficult to do with a flat plane.
OK, too bad, but thank you for the info.
A bit fiddly, but I think similar to how hard it used to be in Tinkercad (which is the reason I moved onto Fusion 360).
But what you can do is create a ‘fillet cutting’ stl shape - and then use that as a negative part scaled and positioned over the edges to round off.
Steps to create the cutter STL.
To Fillet -
Add saved fillet cutter stl by right clicking on the object to fillet and load in the cutter as a negative part
Then when you slice the model the corner will be rounded off
Wow!
I’m still learning.
Thanks for the detailed tutorial!
I never knew that could be done.
Thank you Dave, that ‘procedure’ looks like a pretty easy way to achieve what I want. 
If anyone finds this, I was able to at least make circular prints easily, make a negative torus and scale to slice a circle in the middle.
You can prepare pieces (tools) of different round corners sizes for cut (outside of a corner) and add (inside of the corner, to create an external or internal fillet.
Sizes as 1, 2, 3, 4, 5, 6 mm will always be welcome. You can change how long is the piece when applying, or, if you have time, create several pieces (tools) with different shapes and sizes, and give them names, like Fillet_Outside_0306, meaning a cutting tool with 3mm radius, 6mm long.
While I do see the benefits of these object manipulations for the beginner:
I find the precision often rather lacking.
Take the pictured example of the Bambu cube for the above posting…
Putting the created chamfer SOMEWHERE on the cube is easy…
Like trying to round all four vertical corners of the cube IDENTICAL.
The beauty of those in-slicer-manipulations is that they won’t actually change the model.
You include or exclude things basically layer based.
Good for something but far for ideal for precision.
Try this:
A simple cutlery box for your kitchen drawer.
How hard can it be?
Basic square shaped, nothing fancy…
Sharp angles make the cleaning hard, so need to round them…
Preferable in an even fashion.
Clone one cut out and just scale it wider and longer - easy…
Within a few minutes you have a nice looking box for your spoons, forks and what not.
Won’t fit onto your build plate though.
How do you get those thing walls before or after cutting the model to size so you won’t have to waste a ton of filament ?
Like it or not: It is usually best to make changes to a model using the software the model was created with…
Yes, you can create a bunch of pre-made cutting and adding tools, several different radius and lengths and use them without much precision whenever you need, OR, Bambu Studio “could” have those functions embedded, and it is not difficult, like when you use macros in Excel, it does all the job for you, fast. If you want to fillet an external edge, just select the edge (the same way you do when measuring distances with the ruler), and select radius curvature. The “macro” would have distance and radius, it could create that same “your cutting tool” but in the right place, make the subtract and delete the tool, voila, a simple and efficient fillet, at first for straight lines, it would be a start.
Thanks but I think I’ll pass and use a normal modelling program before I try to mess with the slicer for no reason 
Super helpful!!! This helped me turn a square object into a circle. Will be using this method often!! Wish i could “boost” your post.
