Problem with dimensions adding an extra digit

Hi

I am using AutoCAD 2010

I have a problem with the dimensions on some drawings adding an extra digit to the text

if I offset a line 100mm then draw a line between the 2 lines, the properties of the line show it as being 100mm long. If I then put an aligned dimension between the 2 lines the dimension text shows 1000

Does anybody know why the dimension text has an extra 0

Thanks for your help

if it is on ALL dimensions I would guess that you have a multiplication factor somewhere in your dimension style. If it is only on the odd line I would suggest that you check the Z c=values of each end (although a factor of 10 is quite extreme).

Thanks dbroada

I had a dim scale of 10 change it to 1 which corrects the dimension text. Didn't know you could have a automatic scale with dimensions

Thanks again for your help

very useful when you have a mixture of metric & imperial although I prefer to double dimension when that happens.
