I’ve been learning to use Sketchup to create basic 2D drawings so I can get things laser cut. The shop requires AutoCAD file formats so I’ve drawn something in Sketchup to scale (everything measures millimetre perfect) but when I export to DWG and open this file in AutoCAD the measurements aren’t the same.
Sketchup measures a circle at say 10mm (both top to bottom, and left to right, perfect), but AutoCAD measures the same thing at 9.68mm (left to right) and 9.24mm (top to bottom).
Does anyone know what causes this? I’ve tried looking everywhere but can’t see any reason for this.
