Recently I posted a question about the difference between setting up pieces in components versus groups. Oliver, Mike, and Darryl sent responses that are extremely helpful, and explained the differences and things you can accomplish in components , and gives me more things to look forward to learning. Thanks, guys.
If anyone didn't see the responses they posted, here they are: Originally Posted by Gaffboat
I think the advantage, Jim, is that when you make a component it is available for use in other places in your project. For example, if you need five shelves and make the first shelf a component, you can easily place the other four shelves. Then later if you need to change the shelf dimensions you only need to change one and all the rest change automatically.
With a group you could duplicate and move the first shelf to create the other four but could not make changes to all by changing one. Components can also be shared with other files. So, if you were making kitchen cabinets where the sides are always the same height and depth, you could make one side component and use it over and over again to make various width cabinets, even in a new or different file.
I occasionally group several components if I want to move or rotate them as a unit.
I also recall reading somewhere that using components can reduce the file size vs making everything a group. Originally Posted by MT Stringer

And that part about resizing shelves is the cat's meow! Originally posted by darsev
Just another point to add. Sometimes the component is close but not exactly what is required. For example, the front legs on a workbench are the same as the back legs except for additional fittings for vices etc. In this case, you can copy the component and then make it unique. Changes made to the new component then are not replicated in the original components. Another situation I can think of like this is the mid shelf in a cupboard. This can be copied from the bottom shelf, made unique, and then adjusted as required.
After reading the above responses, I stumbled upon a Jay Bates video that shows a pretty impressive demonstration of the principles described in the responses to my question. It's pretty long (about 30 minutes), but well worth your time if you're a beginner like me and a little overwhelmed by it all. Be warned, Jay moves extremely fast, so you'll need to stop and back up a lot to absorb it if it's new territory. https://www.youtube.com/watch?v=PlnE...4838260#t=1417
And here's the companion video that shows the actual build. I wish I could build things that fast. https://www.youtube.com/watch?v=4y3H3AoL-yY
