: Regarding the F1 ...
: and it's a good idea to enlarge the
: survey drawing to a size that's easier to work from than 8.5 X
: 11 ... I scaled up my F1 survey such that the side view length

Thank you, I will take it easier. ;)
At the moment i am using Gimp to check the measurments and OO_Calc to scale the numbers. It seams that Gimp can easily work on the original file. I wish I won't build a raft instead! ;)
