CONVERT BXL FILES INTO YOUR PREFERRED CAD FORMAT

The free reader is a lite version of Ultra Librarian specifically designed to import vendor neutral CAD data (.bxl files) from manufacturers’ websites and then export symbols, footprints, and 3D models to specific CAD tool formats. The reader is a read-only tool and will not allow users to make any changes to the data. For symbols, footprints, and 3D model creation capabilities, use one of the Ultra Librarian Desktop Software options.
