Split .stl file not possible

I have a STL file that I wanted to print, but… it’s too large to be printed on the P1S bed (had it originally planned to print on another machine). I thought I could just choose the split option, but that doesn’t show in the top bar.
Is there another way to split this one up? Not sure if I can place the stl has I’m not the creator of it.

Split function from context menu is possible only if the STL consists of two or more separate meshes. You can then split them into parts (still working as one object) for color assingment or other operations, or you can split them into objects and place them on different plates for example.

Maybe you are looking for “cut” function instead?

AH… I thought that was the same. Going try and find that then/
