Hi David.
Thanks for the reply. I am referring to the scale when I build objects, e.g. 1cm on the grid = 10m in actual length. With the older version the scale was small, but with the new version x9 it is very large. A small wall of 1cm on the grid shows as 400m actual length. When I compare version x7 with x9 I can see that there is a diffrence in lenght under "Edit" > "Preferences" -> "Number Style". In version x7 it shows 0,1234 m and in version x9 it shows 12,34 m. It is as if the conversion from Imperial to Metric is not working correctly or there is a setting somewhere.
I hope I make sense.
