#### Linear Features

The default number of hits PC-DMIS generates on a linear feature is a system option. To change this value, access the Setup Options dialog box (Edit | Preferences | Setup), and then click the General tab. Type the new default value in the Auto Line Hits edit box. | PC-DMIS can automatically generate hits for lines and planes. To do this:

1. Move the cursor close to the line.

2. Click the left mouse button. (The STATE icons must be set to Program mode.)

Follow these rules for measuring linear features:

- PC-DMIS will generate equally spaced hits along the length of the line at the current probe depth. (See "Setup Options: General Tab" in the "Setting Your Preferences" section for setting the number of hits for lines.)

- The cursor must be placed on the side of the line where the hits are to be taken.

- To automatically program planes, at least two sets of hits at different probe depths must be taken.
