The line type of an object can also be modified by choosing it from the corresponding drop-down list in the Properties group on the Home tab, when the object is selected. However, the initial Autocad configuration for new drawings only includes one type of solid line. So, from the start, there is not much to choose from. Therefore, we must add to our drawings those definitions of type of line that we are going to use. To do this, the option Other from the drop-down list opens a dialog box that, as the name implies, allows us to manage the types of lines available in our drawings. As you can see immediately, the origin of the definitions of the different types of lines are in the Acadiso.lin and Acad.lin files of Autocad. The underlying idea is that only those types of lines that we really need in our drawings are loaded.
