Large Assemblies/Landscaping

I was trying to creat plant layout views for out salesdepartment and have issues. How well does SW handle large models,large in size and possible part count? Can I "Fly through"assemblies? I was hoping to creat some avi videos of a flythroughof the power plant for customers. Is this the wrong software forthis or can it be set up for this?SolidworksGeneral
