Right, this is my 1st post! But I cud see u needed help!
Go to file & then plot style manager, click the create a new plot style wizard. Follow this an u can decide each colours line thickness & colour that it prints out at etc. Then when u print it chose your new plotstyle in the print options list. Hope this makes sense!
Dont think 2000i is compatible with 2006 tho' may be wrong. I know that 2004 created drawings will work back to release 14. altho' this wont help ya
