Step 9: Continue drawing the outline. Use A on the keyboard to lock the line angle.

Note: Alignment guides appear when you are close to another vertex or line.

Step 10: Click the starting vertex to close the shape. The conductor and component keepins are automatically drawn and the outline is automatically selected.

Adjusting the Outline

Defining Board Keep-In Values

Step 11: In the Properties panel, enter 5 for the conductor keep-in value. The conductor keep-in is moved closer to the edge of the board.

Step 12: Enter 12 for the component keep-in value.

Modifying the Outline Boundary

Step 13: To change the boundary of the design outline, right-click and select Edit Boundary. Click to modify the boundary as desired. The board will be automatically cut and filled in.

Step 14: In the Properties panel, under Source, select the rectangle from the drop-down menu to change the outline to a rectangle.

Note: This will erase the custom polygon.

Importing a Board Outline

Step 15: Select Import under source to import a mechanical drawing for the board outline.

Step 16: Browse to the desired .idx or .bsm file, select the file, and click Open.

Step 17: Alternatively, to import a mechanical drawing, open the ECO menu to view other file format options, including .dxf and MCADX. Select IDX Import.

The IDX Import Window

Step 18: The IDX In window opens. Here you can configure settings for the design import. Click Close to close the window

Note: Here you can select the input file, whether to use the mechanical import as the board outline and generate a comparison report.
