Doesn't sound like you're saving your drafting standard under document properties->drafting standard.
I can't get my drawing settings to remain after I set them. I set my font sizes and my dimension decimal places to 3, save my drawing as a sheet template, and when I pull that drawing sheet up again, everythings back to defaults. What am I doing wrong?
There's no such thing as a sheet template. There are drawing templates and sheet formats. Confusing the two is a common issue. I suspect you're saving the sheet format instead of the drawing template. See #2 here: Frequently Asked Forum Questions , and see if that will help.
Those settings are controlled by your document template not the sheet format. You have to create a sheet format apply it to a drawing and then set your font sizes etc. and then save this as a drawing template. It should then work
