Double-click the file in the design pcb1. After the pcb into the PCB design system, you first need to set up PCB design environment. Right-click, select Options design environment settings (Figure l8).
Options There are three commonly used sub-menus:
(1) Board Options: used to set the grid size and component placement step interval. Mesh size is divided into imperial (Imperial) and Metric (Metric) two standards. Foreign production of integrated circuits generally use imperial norms, for example, dual in-line, (DIP) pin spacing of 2.54 mm (tenth of an inch), so when placing components generally choose to use imperial grid.
(2) Layers: PCB board layers used to set.
(3) Display: PCB board for setting the elements to be displayed.
In addition, you can set the cursor menu preferences, lamellar color.
Options parameter should be set in line with personal habits, usually after a set without further modification. Most parameters can use the default values.
