Assigning Line Types to Layers AutoCad Help

You will often want to use different line types to show hidden lines, center lines, fence lines, or other noncontinuous lines. You can set a layer to have not only a color assignment but also a line-type assignment. AutoCAD comes with several line types, as shown in Figure 4.18. From the top of one image to the bottom of .” the continued image of Figure 4.18, we can see Standard line types, then ISO and Complex line types, and then a series of lines that can be used to illustrate gas and water lines in civil work, or batt insulation in a wall cavity. ISO line types are. designed to be used with specific plotted line widths and line-type scales. For example, if you are using a pen width of .5mm, the line-type scale of the drawing should be set to 5as well. (See Chapter 12 for more information on plotting and line-type scale.) The complex line types at the bottom of the figure offer industryspecific lines such as gas and water lines for civil work, and a line type that can be used to symbolize batt insulation in a wall cavity. You can also create your own line types.

AutoCAD stores line-type descriptions in an external file named Acad. 1; n. You can edit this file in a word processor to create new line types or to modify existing ones. You will see how this is done

Adding a Line type to a Drawing

To see how line types work, add a dash-dot line in the bathroom plan to indicate a shower curtain rod.

1.’ Open the Layers Properties Manager dialog box.
2. Click New and then type Pole to create a new layer called Pole
3. Click the word CONTINUOUS at the far right of the Pole layer listing (under the Linetype column). The Select Linetype dialog box appears.
The Select Linetype dialog box offers a list of line types to choose from. In a new file such as the Bath file, only one line type is available by default. You must load any additional line type you may want to use.
4. Click the Load button at the bottom of the dialog box, The Load or Reload Linetypes dialog box appears

Notice that the list of line-type names is similar to the Layer drop-down list. You can sort the names alphabetically or by description by clicking the Linetype or Description buttons at the top of the list.
5. In the Available Linetypes list, scroll down to locate the Dashdot line type, click it, and then click OK.
6. Notice that the Dashdot line type is now added to the line types available in the Select Linetypc dialog box.
7. Click Da~hdot to highlight it; then click OK. Now Dashdot appears in the Pole layer listing under Linetype.
8. With the Pole layer still highlighted, click the Current button to make the Pole layer current.
9. Click OK to exit the Load or Reload Linetype dialog box.
10. Turn off the Running Osnap mode; then draw a line across the opening of the tub area, from coordinate 4′-4″,1′-10″ to coordinate 4′-4″,6′-10″. Metric users should draw a line from coordinate 133,56 to 133,208.
