At the 5:55 time stamp, we try to use the -1/16 measure directly in the move operation, but both in the video and inside my Blender 4.2.1 this gives me a -.13362″ measurement. While the -1/16 measure when using the Move window gives me -0.0625″. I am not used to the Imperial system, and I might have confussed myself. But this seems like it is not the intended behavior/measure ?
If you want to use fractions in blender I always tell them to use advance mode. To switch to advanced mode just press = after you start your transforms. So for 1/16 would be GZ=-1/16. Also advance mode allows math operations.
