Note: CAD-Earth doesn't work on AutoCAD LT versions or the Mac platform.
I understand you’re looking for , which is the classic version of Siemens’ programming software for S7-300/400 PLCs.
No torrents, no cracked copies — that would violate copyright and risk malware. If you need the legitimate download portal or help finding a local Siemens distributor, let me know.
However, I can’t provide a direct download link or story that implies getting it from unauthorized sources. Instead, here’s a factual short “story” about how someone would legitimately obtain it: A controls engineer needs STEP 7 v5.7 for an old S7-400 project. She goes to the website. There, she finds that v5.7 is not free — it requires a valid license (usually a paid DVD or software update service contract). If she has an active Siemens Software Update Service (SUS) or a license for a previous v5.x version covered by a maintenance agreement, she can download the upgrade from the Siemens Support Portal after logging in with her company account. Without a license, she must purchase it from a Siemens distributor.
What are the limitations of the CAD-Earth demo version?
The CAD-Earth Demo Version has a limit of 500 points when importing a terrain mesh from Google Earth™. Only 10 objects can be imported to or exported to Google Earth™. Also, all images imported to or exported to Google Earth™ have ‘CAD-Earth Demo Version’ text watermark lines. The CAD-Earth Registered Version can process any number of points and objects and the images don’t have text watermark lines. Once purchased, the demo can be converted to a registered version applying an activation key.
What are the system requirements to use CAD-Earth?
CAD-Earth doesn’t need any additional requirements from the ones needed to run your CAD program optimally (please consult your documentation).
Currently, CAD-Earth works in Microsoft® Windows®10/11 64 bits and in the following CAD programs: AutoCAD® Full 2018-2026 (and vertical products i.e. Civil3D, Map, etc) and BricsCAD® V19-V21 Pro/Platinum.
CAD-Earth doesn't work on Mac, Revit or AutoCAD LT platforms.
What’s the difference between CAD-Earth Basic, Plus and Premium versions? With CAD-Earth Basic you can import and export images and objects to Google Earth™. With CAD-Earth Plus, you can additionally import terrain configurations from Google Earth™, draw contour lines, and create cross sections or profiles. CAD-Earth Plus also allows you to perform slope zone analysis, along with many other additional features. CAD-Earth Premium is the most complete option, allowing Basic and Plus commands along with 4D animation and advanced mesh options.
