 In model space: In this process, everything is drawn in model space, which at one time was the only known universe in AutoCAD. The drawing is created full size, while text and dimension component sizes, hatch pattern scaling, title blocks, and borders are all created at the inverse of the final plotting scale. This was the only way for many years, so you’ll encounter many drawings that were made this way.

 In paper space: Finally, Autodesk programmers figured out how to tunnel through into a parallel universe called paper space, which revolutionized drawing production. Current preferred practice is to draw the object full size in model space, cut a viewport in paper space so you can look through to the model space, and then apply documentation such as dimensions and text in paper space.

The next decision to make is what kind of border your drawing needs. The options include a full-blown title block, a simple rectangle, or nothing at all around your drawing. If you need a title block, do you have one, can you borrow an existing one, or will you need to draw one from scratch? Although you can draw title block geometry in an individual drawing, you’ll save time by reusing the same title block for multiple drawings. Your company or client should already have a standard title-block drawing ready to use, or someone else who’s working on your project may have created one for the project.
