This is my first time posting a question so please have some patience. I have been using Sketchup for several years but have never explored the means and methods to reducing file load to optimize performance while working on a larger complex model. I am proficient at using the basic drawing tools, components and such but have never assigned layers or other controls to my models. I also am not CAD savy and do not have a knowledge base or practice in file structuring. With this context, can someone point me to some written instructions as to how to best organize the file in chunks or segments such that pieces can be edited to increase computer performance times while still keeping the entire model in tact such that it can be reactivated to produce final stills and animations? The files in question do not have any CAD files or lagrge photography txtures but they do include 3-d cars, people vegetation and other sketchup produced objects. The colors and textures are mostly sketchup based although a few are from .jpg origins from outside sketchup. I do not think these are causing any excessive file density.
A good step by step strategy to accomplish the above would be greatly appreciated.
Thank you in advance.
