CAD:Drawing Spaces Explained

Description

The CAD file is structured to reduce errors of scale. It does this by creating an infinite coordinate system. This allows you to work without the limitations of paper. We don't have to scale our idea on to the page. We can work at any scale we want and worry about the printed output only when in comes time to deliver.

The CAD file has, at the minimum, two drawing spaces.

1. The Model Space. This is where we drawing our drawing.
2. At least one Paper Space (referred to in DWG2000 and forward as Layouts). Here we lay up our drawing for print. The Paper Space can contain entities like page borders and text.

The Paper Space must also contain at least one ViewPort.
