Step 8: Rearranging Layout
Since letter and A4 paper are different sizes, the pieces will usually not fit after you change the paper size. You will need to re-align them to fit on the pages.
First, get rid of the 3D window, so that you will have more room to re-arrange the pieces. Select the "Configuration" tab, and click on "Show Only 2DPatternWindow".
To space the patterns out, you'll need to use the "Select and Move" tool. You can select it in the right-click menu. Now, arrange all of the piece so they all fit on the pages, and don't overlap. You can put as many pieces on one page as you can without overlap, but some space aids in cutting it out.
Using only the "Select and Move" tool, you can arrange all of the pieces. However, if you don't want to waste paper, you can use the "Rotate Part" tool to arrange the pieces closer, and conserve paper.
To use the "Rotate Part" tool, select it in the right-click menu. Now when you click on a piece, small circles will appear on its vertexes. Select a pivot vertex. There should now be a cross hair on it. Now, click and drag another vertex in order to spin the piece.
Position your parts to your satisfaction.
