I have an STL image (of arteries in the brain) and I want to get 2D slices or z stacks of this. I installed the 3D viewer and was reading somewhere that there is a way to convert this into stacks? However, when I open the stl in 3d viewer, it does not give me an option to view it as orthogonal slices/surface etc (all those options under ‘Edit’ are greyed out). I also can’t use the regular stack menu under Fiji/ImageJ with this STL as it is open under the 3D viewer and not as an image, so whenever I try to use any of the regular menu, it just says no image is open.
Can someone please help me with creating slices/stacks from this stl? I would really appreciate it. I tried uploading the STL but I guess the forum upload doesn’t allow STL files.
