You can check how big your model is by going to Window > Model Info
> Statistics. Make sure the Show Nested Components option is checked.
This will tell you how many faces and edges there are in your model.

3. Organize your model from the start. Use layers to organize your model

and to control visibility. Think about creating a system for naming your
layers. For example, you could make all the structure layers start with
“S-___,” all the architectural layers with “A-__,” and so on. We like to use
layers starting with “1-___” for all new work.

4. Use layers and groups/components to nest geometry. You can and

should make groups/components out of smaller components. With the
layers, you can create a hierarchy of geometry or nested layers.

In this example, the numerals 1, 2, 3 are individual components and are
grouped together as a component called Numbers. So, you can turn off
or hide all the numbers by unchecking visibility of the “0-number” layer,
or you can switch off each individual number. This is same with the letters
too. Also note that the Nesting layers have a zero leading their names.
That way they are at the top of the list. Although this is not important
when there are only nine layers, this does matter when you have
500 layers.
