Use drawings to create and access project data.
There is a tight association between a project object, such as a surface, and its source drawing, which is the drawing that contains the object. To create a project object, add the object’s source drawing to a project and specify that you want to share the object with others. You can edit a project object by checking out the source drawing, making the change, and checking the source drawing back in.
You can store any project drawing in the project database. You will find it easier to keep your project organized if you use more than one folder to store your project drawings.
The Drawings collection in the Prospector tree is not a folder and does not map to a folder in either the project database or the working folder. However, the folders under the Drawings collection map directly to folders in the project database and the working folder.
