Diferent computer = different model scale?!

I am working with my computer in my office and sometimes later at home with my home-portable…My surprise is that my 3d model created with grasshopper (open street map + elk) which uses extruded polylines, scales the extrude scale different in my home computer compared to my office computer…
Does anybody know which setup value is different in my rhino-grasshopper at home compared to my office? because I supose this is the origin of my problem…something related to initial scale setup? something that changes extrude size effect…
thanks in advance for your time and help, dear friends.

Have you checked that the Rhino are in the same units?

Not yet…tomorrow I will check it at the office…its weird because I did the same installation, but who knows…yes I will check it …

thanks!
