Hi, I am working on my first "Top Down" design.  I started with a sketch in my assembly of 3 mating parts.  Starting here in the assembly instead of with individual parts has worked beatifully for working on the intricate connections between the parts in one place as my design evolves.  However, my middle part will have 3 different configurations, each a different width. The only way I have found to accomplish this is by changing my layout sketch in 3 different configurations (at the assembly level - cannot do it at the part level).  This worked great until I started to make drawings of my parts and realized that since all of the parts' orgins are linked to the assembly origin, when I change configuration to a wider middle part and it pushes the third part over It changes the origin of the third part (since its now further from the assembly origin).  This then moves the drawing view in my drawing file.

Am I going about this correctly?  Is there an easier way to have these parts share sketches at the connections?  If not, is there a way to break the link of the part's origin to the assembly origin and still have it linked to the original layout sketch?

Thanks in advance for everyone's help!
