(Laying out the board)
Now you will create the board outline. The things you need to consider are the following:
| |||||||||
Select the Obstacle button from the tool bar . | |||||||||
Select the Global Layer from the layer pull down list . | |||||||||
I usually place the board above the drill chart. Click on the workspace for the lower left corner, then move up click, move right click, move down click then press ESC. A yellow box should trace out. Use the X Y coordinates in the upper left to determine your outline size as you trace. Remember, I'm using mils or 1000th of an inch. My example is 2" x 3". |
Click on DRC so that it's gray. The Design Rule Checker feature gets in the way at the beginning of the process. The dotted line should disappear. | |
The datum is the reference place for the coordinate system. The datum represents 0,0. I prefer that the lower left corner of the board be 0,0. Go to Tool -> Dimension -> Move Datum. Click on the lower left corner to move the datum. | |
Select the component button from the tool bar and "TOP" for the layer . | |
Start moving components to within the yellow outline. |
The board we are building only has a top and bottom (no inner layers), so go to Tool -> Layer -> Select from a spreadsheet ... |
Select a Layer and from a right click choose "Properties" to edit the layer. Change the GND, POWER and any INNER layer to say Unused. |
Let's take a second to look at the nets.
