Good Morning !

I have a problem with my SketchUp, where in my project comes a moment that it starts to get very slow when I will put the 3dwarehouse objects. Please, can someone help me?

Follow the link of my project for analysis!

Don’t download content from 3D-Warehouse directly into your project file. Import them one by one into a new SketchUp instance first to examine them to see if they are any good at all. You may want to clean them up first and/or make them less heavy. Only then import them in your project file.
