Select the 2-track bridge in my design and copy it. Now open a New Layout and paste the copy into it. I suggest moving it closer to the upper left 0,0 location on the page. Then save the file with an appropriate file name.
If you want any of the other objects from the link I posted, you have to right-click on the Quick Download button and use the Save File As option otherwise all you’ll see is a text file that won’t mean much to you. For each one you’ll get a separate SCARM file. If you open the files, you need to use the 3D view to see what’s there otherwise it won’t look like much.
