Folder Setup for a Large Project
For a project to be successful it requires a good folder directory structure. One which is quick and simple to use, yet files things in an orderly way, so we have information at our finger tips. That means we can find things quickly, and not lose things! In this video we discuss a folder setup on an actual structural drafting project for a large building. We also articulate the … [Read more...] about Folder Setup for a Large Project
