Board Shape refers to the geometry of the edge of your board and any internal cutouts. Most board shapes are rectangular but you can create more complex shapes. For example, you can create a circular board or a board with intricate cutouts.

You can set or change the overall size of your board. For example you might want to increase the size of a board to allow room for adding more components.

alt To change the dimensions of a rectangular board:
  1. From the toolbar, turn on Snap To Angle mode.
  2. Drag the right edge of the board outline or select the edge and use the Left/Right arrow keys.
  3. Move the top edge similarly.

You can create boards of custom shapes. For example you might need to create a round board to fit into a round enclosure.

alt To create a custom circuit board shape:
  1. Choose the Selection tool.
  2. Select the existing board outline; press the Delete key.
  3. Choose the Trace tool.
  4. On the Property Bar, select Board layer.
  5. Draw the desired board shape by drawing traces using straight lines, arcs and/or circles. When using the circle tool choose outline style, not filled. Close the shape. Avoid line intersections.

You can create custom shape holes or cutouts in your board. For example you might need a square hole to fit around a heat sink.

alt To draw a custom shaped hole or cutout:
  1. Follow steps 3, 4, and 5 above.

You can add an edge connector to your board (e.g. see the preview in the Job | Settings | Specifications dialog).

alt To add an edge connector:
  1. Use the Trace tool to draw the connector fingers, stopping at the board edge.
  2. Use the Polygon tool on the unMask layer to add a rectangle encompassing the fingers (to allow electrical contact).
  3. For gold plating check Job | Settings | Specifications | Advanced "Gold fingers or gold plating required".

Changing the Origin

Pad2Pad specifies object locations in X,Y coordinates with origin at 0,0 at the lower left corner marked marked by a + symbol. You can move the Origin Point. For example you might want to put the origin at the center of a mounting hole.

alt To move the Origin Point:
  1. Choose the Selection tool.
  2. Select the object to use as reference.
  3. Choose Edit | Origin Point... ; the Shift Origin Point dialog appears.
  4. Specify the horizontal and vertical offset for the origin point.
  5. Click OK.

alt Origin Point coordinates are always shown relative to the current Origin Point position. On entering the Shift Origin Point dialog it always shows zero coordinates.
