i dont think it will create problems in gerber generation
but switching between units very often is not advisable
Thanks for your reply,from your point of you it is not issue right, but units some time maybe rount off like,if i change the mils-->mm (6mil--->0.1524mm) like that appeared or some time it will appeared 0.152 why ??
What value you got when u switch back to mils?
I do not have any problems in 9.5 version
May be in 2005 it supports only 3 digit accuracy in MM
If switching the units many times from mils to mm and mm to mils the round off error will occur .So better to keep single unit as much as possible.
Thanks and Regards
