When placing, routing and laying out a PCB based on a schematic (such as with this project) we
will be working with components.
The Board Edge
Before we can place the components on the board we need to define what shape and size the
board will be. For our project we need only a simple rectangular board edge but we do want to
control the dimensions of the board (115mm wide and 40mm high).
The first thing to point out here is that Proteus will operate in either imperial or metric units and
you can switch between modes either by toggling the Metric command on the View menu or via
the ‘M’ keyboard shortcut. You may need to switch units for the placement of the board edge
and also elsewhere in the documentation.
You can set your default or preferred units from Technology Menu - Grid
Configuration command.
To start placing the board edge, select the 2D Rectangle icon from the left hand side of the
application.
