I am just now creating parts in an Assembly. In the past I have created seperate parts and inserted them into the Assembly. Anyway, when I create a part in an Assembly set up as inches (IPS), the part is metric. I know how change it back to inches, (Options > Document Properties > Units > IPS) but when I create another part it goes back to metric. Is there some setting that I have missed so that parts created in my IPS Assembly will also be IPS?
