This task can be resolved in two different ways.

Solution #1

1. Prepare the desired layout and decide which pieces you want to unite (see Fig.1).
2. Select the "unnecessary" knives or, in other words, the knives that hinder from uniting the pieces (see Fig.2a).
3. Hide these selected knives by clicking on the OFF button located in the Main window of the plug-in (see Fig.2b).
4. Now, if you cut the image by clicking on the Cut button located in the Cutter window, then you will see that one big piece has appeared instead of four small pieces (see Fig.3).

In particular, this method was used while preparing the A2 and B3 samples of our on-line Gallery.





Solution #2

As far as you can see, using the Solution #1 lets you obtain the large piece from several small pieces and the new piece carries the knobs that have remained from former pieces. In many cases this is undesirable result, because you may want the big piece to have its own knobs (one knob on a piece's side). Thanks to the new option of Puzzle Pro 3.x that allows you to add an extra knife between two knots, this task can be easily fulfilled.

1. Let's take the same layout (see Fig.1) and the same pieces that you will unite.
2. Select all knives that are related to the pieces you want to unite (see Fig.4a) and then hide these selected knives by clicking on the OFF button located in the Main window of the plug-in (see Fig.4b).

3. Select two knots and then, click on the "+" button (located in the Main window of the plug-in) to add the extra knife between these knots (see Fig.5a). (You may also review the How to add an extra knife? topic of the User Guide.)
4. Do the similar operations and add 3 more extra knives (one by one) to complete the large piece (see Fig.6).

We have used this method for B2 sample of our on-line Gallery.
