RE: [bolger] Re: brick
- When I was at college I spent some time in a workshop building things on
lathes etc. It seemed pretty common place to include the minimum number of
dimensions to the point that occasionally they would need to be calculated
from the numbers that were shown.
On the plans for the boat Im building ive sometimes been unable to find
dimensions. They are there, its just that they are difficult to find.

It's good practice not to "double dimension" anything, as if you have
little errors you can get conflict between the dimensions. Best to
put in the dimensions needed to make the part. If you add any extras
you mark them "ref", but I bet if he put those on the plans, people
would use them, mess them up, and then look at the other dimensions
and decide it's all wrong.
