stlread not working as expected

Hi everyone.

I have an STL obtained from 3D slicer, and if I import it to matlab with stlread ('STL.stl'), I don't obtain a triangulation with points and connectivity list (which I got for other STLs with the same command), but a 1x1 struct containing the coordinates of faces and vertices .

Does anyone know why?

Do the fields of the returned struct happen to be named 'Points' and 'ConnectivityList' ? If so, then somehow you would have received the struct() of the triangulation object.

Would you happen to be able to zip the .stl and attach it for us to test ?

No.. they happen to be named "faces" (561000x3) and "vertices" (1683000x3).

Here is the STL: https://1drv.ms/u/s!Al2T9TjVMCRBick_XCuYHFiRHpb1KA?e=exWsYf

Which MATLAB release are you using? I just tried in R2021b and I get a triangulation out, which is what is expected.

Solved, I realized I had the function "stlread.m" in a subfolder, that made the built-in matlab stlread do something else then expected. Thank you!
