Wrong Size in AutoCAD? Use SCALE, Not UNITS #autocadblocks #autocad #engineeringdesign #cadbury

If your AutoCAD drawing is the wrong size, changing UNITS will not fix it.
When you type 100 in AutoCAD, the software only stores a number.
It doesn’t know whether you meant millimeters or inches.
UNITS only control how values are interpreted.
SCALE is what actually resizes your drawing.
This short explains the difference clearly and shows the correct way to fix size issues.
Perfect for AutoCAD beginners and civil engineering students.
