Making Printed Circuit Boards with Orcad Layout Part 2

(Setting up Layout for your Capture Schematic)

	From file menu select "New".  The "Load Template File" dialog box will appears.
	Go with DEFAULT.TCH, unless you are doing something special like an ISA or PCI board.
	Select the *.MNL file you made a note of in Capture.
	Save the layout file.  This is the file you will open to make changes to Layout later.
	The Automatic ECO Utility will prompt you to select a footprint to the component.  Click on "Link existing footprint to component ...".  You can either browse the library or see the Footprint Library book in J207 to make things easier.  If you want to modify a footprint, do it later in Layout versus using the "Create or modify footprint library ...".  Modification takes time and is easier within the program.
	Here's the selection for the LM747.  I selected the DIP100T library to give us footprints for Dual In-line Packages whose leads are 0.1" apart, and are Through hole components (versus DIP100B which are surface mount).
	Under footprints, select DIP.100/14/W.300/L.700 which is a DIP Chip with pin that are 0.1" apart, 14 pins, and a component silkscreen (the green box) that is 0.3" X  0.7".  Don't worry too much about the silk screen.  We buy economy prototyping boards that do not have the silk screen.  If we were building full production boards, it would appear as the white writing on the board.
	Now your design should look like this.  A drill chart and a bunch of footprints connected together by the ratsnest.
	The ratsnest shows the interconnectivity between the components.  It helps with placing the components.
	In the menu bar go to Options -> System settings ...
	Click on "Workspace Settings...".  Note:  This box is also used to adjust the grids for custom parts or placement.

I'm going to chose a "Very Small" workspace.  !7" X 17" is still larger that I will ever need.  Then click on Convert.. and then OK.
