You can start a new drawing several ways, including starting from scratch or using a template file. In each case, you can choose the units of measurement and other unit format conventions.
A quick way to begin a new drawing is to start from scratch, which starts a drawing that uses settings from a default drawing template file.
A setup wizard establishes basic drawing settings step by step.
A drawing template file contains standard settings. Select one of the template files supplied, or create your own template files.
Before you start to draw, you decide on the units of measurement to be used in the drawing, and set the format, precision, and other conventions to be used in coordinates and distances.
You can keep track of your drawings more easily if you add keywords or other information to them.
