Valid stl file (case sensitivity) #155

Closed nilswagner closed 3 years ago

nilswagner commented 3 years ago

Is the file HalfDonut.stl a valid stl file? solid HalfDonut.stl ... ENDSOLID HalfDonut.stl

An ASCII STL file begins with the line

solid

The file concludes with endsolid

What about case sensitivity of endsolid?

As far as I am aware the standard doesn't specify anything about needing either upper or lowercase. I've changed the file as a test for a case sensitivity fix recently: https://github.com/WoLpH/numpy-stl/issues/154

I do believe it's valid but I'm not certain. Up to a week ago this library only supported the lowercase version but it doesn't matter much either way I think.

The new release supporting case varying STL files is now online :)
