I got this model from the 3D warehouse.
Two plates of different sizes. I went into one of them and realized the other one was also being adjusted. They are components even though they aren’t exactly the same size??? What???

There aren’t actually different. Evidently you made a copy of the large one and scaled that copy down to make the smaller one. You neglected to use Make Unique to separate them so they are still instances of the same component.
BTW, you have exposed reversed faces. You should correct them.
You should also take a look at Outliner. It will show you that they are instances of the same component.
Is there a reason why the rim of the plates is a group while the center is just loose geometry combined with the group into the component?
Edit to add a couple of other observations. These are fundamental modeling things.
The normal wisdom is that you should turn off Length Snapping for your modeling. For something the size of these plates, it would be better to use something other than Architectural units and higher precision.
When drawing circles you should drag out the radius on axis and not in some random direction as you’ve done here. Dragging out the radius on axis makes the object easier to work with and more predictable.
As I said, I got this model from the 3D warehouse. I drew none of this. I still don’t understand how these are components yet different. Surely you noticed that if you go into one of these to make adjustments, they are still components? Can you help me understand?
I’ve already showed you, the two objects are instances of the same component. One component has been scaled down but they are still the same component. They are only different in size. Entity Info shows there are two of the same component.
Look at Entity Info. There’s only one component definition.
Look at Outliner. It shows two instances of the same component.
Here I’ve modeled the plates correctly. Each one has a different definition. Note in the difference in what Entity Info shows. There are two different components shownin the Components panel. And Outliner shows each one as a different definition.
You should take some time and go through the SketchUp tutorials to learn about this. learn.sketchup.com
I didn’t understand most of what you said, but I just made a component in my own model, made a copy, and realized I could scale it without affecting the component relationship. In case anyone else comes to this thread looking for this information.
Due to the way they work and the somewhat sloppy language often used when dealing with SketchUp components, it is easy for non-technical people to be confused.
A component is really a complex idea with two sorts of things associated with it: 1) a “definition”, which is like a specification of how to build one - what it contains, and 2) zero or more “instances”, which are actual things created in the model according to that specification.
Each instance has several properties that are uniquely associated with it, including its location, scale, name, and other non-geometry data. The two plates you are seeing are instances of the same definition, with different scales.
When you open a component for edit, you are actually accessing the definition via one of its instances and modifying the definition. Part of the magic of SketchUp’s components is that every instance remembers what definition was used to generate it, and is automatically updated if the definition is altered.
If you made the first object a component and copied it without making the copy unique, modifyin one will modify the opther. Simply scaling one of them without opening it does not break its relationship to the other.
If you made the first one a group instead, you can modify one copy without modifying the others.
Thank you Steve
simple trick, if you enter a component, you impact all of them. if you stay outside, you impact a single one.
it works with pretty much everything, move, rotate, copy, paint, scale, draw…
Just a simple gif to show what everyone has said.
The difference between scaling the component instance and the component geometry.
This is a helpful way to understand components!
