I'm trying to apply a linear dimension to a line, however, whenever I place the dimension the size of it is so massive that it's even greater than the size of the part I'm working on itself. I'm a student following a demo video from my instructor and having followed everything he's done should have the same settings as him, however I can't find any setting to change that would effect this. Any help would be appreciated.
It maybe caused by Drawing Scale
You can also use the function by turn OFF the drawing scale.
