On Chitubox v1.6.3 if I load a file I created in Fusion360 using inches, Chitubox incorrectly scales the item when I let it scale it via the pop up.
If I go into Fudion 360 and change my model to mm and export and load into Chitubox the file lids correctly and is printed I. The correct size.
Unless there is a setting I am missing, I think there is a bug in the way Chitbox accepts a file when it is defined in inches.
