I have a square objwct where I want end up with a circle object cropped, with the circle saved, the straights corners deleted. Such an option is not available with the cut tool for some reason. So how can I do it?
Thanks
You can create negative modifier of needed shapе. Then use combine/difference and substract said modifier from your object.
Doesn’t that remove the middle and keep the outer?
This is the square, light part. I want to keep the area inside the yellow circle. Everything outside the circle is to be deleted.
in theory you should be able to do this with a boolean combine and a cylinder, but both bambustudio and orcaslicer always fail me on anything complex.
A tool i know of to do this would be MS 3d builder
Import model
Ensure model is MANIFOLD aka fixed
Add cylinder that covers all of the space you want to keep
Select cylinder AND object and then edit → intersect
Export as obj/3mf/stl
So you have put a negative sphere in there but it sounds like what you want is a cylinder with X, Y, Z dimensions?
Do you want a cylinder or do you want a cube with fillets on the 4 vertical corners?
Looking at your 3d landscape, I think what you want is to use an operation to capture everything inside a cylinder. You want to make a cylinder whose ID is the inside of your tan sort of circle. The OD of cylinder will be such that cylinder wall thickness will be the distance to corner of landscape. I’m assuming you want a perfect circle.
I have used a solid cylinder to punch holes in objects using primitives in Studio and concept is pretty much same in OpenSCad and Fusion.
Try right clicking on landscape and see if you get an box that has Primitives as an option. If yes, choose it and seee what your shape options are.
If that doesn’t call the flyout, deselect your model and right click on build plate. One of the two should get your primitives.
Start a new project, add a primitive “cube”, scale it larger than the model in all directions.
Add a negative part, primitive cylinder in the center.
Export as “hole.stl”, this is your cutting tool.
Load your model as a new project.
Add a negative part, Load “hole.stl” as a negative part and position as desired.

The corners should disappear after slicing.
So something is wrong then, that the corners are still there after slicing (the black areas)?
Try making the X and Y longer. It will toss the excess so it doesn’t need to be so close. Tack on 5mm on X and Y and then slice. Z also needs to be taller than the tallest building.
Make longer which - the object or the hole?
Yeah, I’m seeing the same problem in OrcaSlicer. Add Negative Part>Load… hole.stl is not being treated as a negative object.
Right-click on hole.stl, Change Type, make it a Negative part, slice.
Now the question is… why did Loading a .stl as a Negative work for me earlier?
What you call hole. Upper left picture.
Still not working. Seems it is indeed a negative part when imported. Change type does nothing.
Earlier I was testing in Studio, not OrcaSlicer.
Studio, Prepare:
Studio,Preview does not show “corners”. In Line Type display, Preview still shows buildings “grayed out” outside the hole, but those do not actually print.
=================================================
And now when I try again in Orca, the hole loads and slices as a negative part, as it should.
I HATE intermittent problems!
You mean increase the diameter of the hole, or the outer edges of the cube?
My Preview still shows black corners. I think I did as u explained.
