What exacly determines that a part is listed in Parts Lists as EACH or for Length f.e.?

Hi Infoseeker, 

You can set this in the part by going to the Tools tab > Doucment Settings > Bill of Materials tab,  and setting the Base Quantity setting.

I hope this helps.
Best of luck to you in all of your Inventor pursuits,
Curtis
