Lambda makes extensive use of Adobe's Acrobat file format. Your browser may be set up to view these files, if not when you select a file you will be asked to download it. To view it later on your computer, you will need to use Adobe's Acrobat Reader software.

Lambda also provides CAD files (.DWG) for your convenience. You must have Auto-CAD or an Auto-CAD file viewer, such as Volo View, to view these files.
