When you would like the stitches in an object underneath to be deleted automatically where the upper object overlaps, use the "Mask" function of Editor. This function can be used only for two or more selected objects.
Note: If you want to apply the "Mask" function to a single object, you must first split it in such a way, that you separate the underneath layer into the first object, and the upper layers into the second object.
1 - Run Embird and click "Editor" menu to switch to Editor window.
2 - Select "File > Open" menu to open the first design (Picture No. 1).

3 - Select "File > Merge" menu to bring in the second (upper) design (Picture No. 2).
2. Merge the second design
4 - Select the objects you want to mask. In this case, there are only 2 objects on Work Area, so click "Edit > Select > Select All" menu to select them. As you can see at the right side of the screen, both objects are now selected (Picture No. 3).
3. Select both objects
5 - Select "Edit > Stitches > Mask" menu (Picture No. 4)
4. Select "Edit > Stitches > Mask" menu
6 - A dialog box will appear on the screen allowing you to modify the "Pull compensation" parameter, which specifies the overlap between the upper and bottom objects on the edges of splitting (Picture No. 5).
5. Specify pull compensation
7 - Use "File > Save As" command to save the whole design to a file on your disk. Specify the format and the file name of the new design in the dialog boxes which appear on the screen.
8 - Finally, check the results of the mask function. Click "Edit > Select > Deselect All" menu to cancel the selection of objects. Then move the mouse pointer to the upper object (dog), depress the left mouse button and move the mouse to change the position of the upper object. You can see that the stitches in the bottom object were deleted automatically where the upper object overlaps (Picture No. 6).
6. Move objects apart to check the result
