You can create 2D drawings of the 3D solid parts and assemblies you design. Parts, assemblies, and drawings are linked documents; any changes that you make to the part or assembly change the drawing document.
Generally, a drawing consists of several views generated from the model. Views can also be created from existing views. For example, a section view is created from an existing drawing view.
Topics about drawings include:
Creating standard views (model views and standard 3 views)
Creating derived views, such as detail, section, projected, broken, and so on
Dimensions, notes, datums, geometric tolerances, and other annotations are discussed in Detailing.
