The PADS Maker Layout environment is simple in that it consists of three primary windows: the Design window, the Project Explorer, and the Output window.
The Design Window
The Design window is where the board is built.The window displays only the currently open design.
The Project Explorer
The Project Explorer displays a list of all layers, components, decals, and nets currently existing in the design.
Clicking the plus sign beside each category will expand each category into the appropriate subcategories and individual items. Clicking an item in the Project Explorer will zoom the display in the Design window to that item. You can select multiple items by holding down the Ctrl key while selecting each item.
The Output Window
The Output window is where you will find all error messages and notes that you may encounter while you are building your design.
