Why would you mate all your components to the assembly origin instead of other components?

There is this debate going on in my company about how we should mate our assemblies together. We have a huge stability problem, which I am currently trying to fix. Anyway one of the suggested solutions was to mate every components in the assembly to the assembly origin. I for one think that this is the worst idea I have ever hear, but I am trying to keep and open mind and would like to hear from others on this topic.


Just to make sure you understand what I am asking let me walk you through my thinking. What I was taught was that you would insert one component a "base" if you will. That component it could either be manual mated to the planes or just hit the check mark and solidworks will put it in place and fix it. Now that the first component is fixed you would start adding components and mate them to the "base" and other components until you are out of components and the model is fully defined.


what my co-workers are suggesting is that each component would be modeled up in a part file a specific distance from the origin. when you insert that component into your assembly you would drop it in and select the origins to mate to and align the axis. As far as what I was taught in school is that your assembly is now "dumb". it is not intuitive and will not adjust if there are modifications made. I am just wondering if there is some benefit that I am over looking when it comes to this form of matting?


thanks and have a great day
