Not that i know of.. i was in the middle of doing the dimensions.

most of the dimensions were of sealed rectangles and one had a gap. so when i got to this one i could not use the Dim Command so i switched to the Dimlinear Command and this is when it changed and i cannot get it back to the settings even when i switch back to the Dim Command 

as a dwg file or a screen shot?

here you can see the cold store is how i set my preferences, and the prep tent is the one with the break in the line

Hi Maxim..

here are two screen shots showing the settings for each of the different dimensions

and here is a screen shot of my settings for dimentions

ok so i changed it back to standard and no change. 

any other options i can try ?

here is the DWG file..

ok great..

so you will notice that most of the Dims have arrows and are all the same in text size (these were done with the normal Dim tool) except the one on top of the prep tent (5000mm) and the on on the servery (2500mm) where i used the Dimlinear tool

all was going fine as i worked my way clock wise from the bottom up until i hit the prep tent which has a break in the line which is why i had to switch tools. 

from this point the text size shrunk and i had to manually go in to the dimension to resize the numbers. but ive lost the arrows too..

i did not change anything during the whole process so it seems to have changed when i switched tools

yes these are the problem dims

Hi Maxim.. yes thats perfect.. what was i doing wrong?? strangely now that i have opened your one my old one works correctly.
