Open the two projects (each in its own browser tab or window).Sometimes you might want to copy or move a wireframe (or a few) from one project to another. The export dialog will ask you if you want to export only the selected controls or the entire wireframe. You can also export a subset of the controls in your wireframe by selecting them on the canvas and using the Export Current wireframe to PNG command. Exporting all wireframes will also generate images for any alternates you have created. The shortcuts for exporting a wireframe and project to image files are CTRL/ ⌘+ R and CTRL/ ⌘+ SHIFT+ R, respectively. Note: If you check the 'Use Transparent Background' option (in the Project > Export menu), the exported image(s) will be transparent anywhere the canvas shows through in the wireframe.
