Close Google Earth™ and any CAD product that may be running on your system.
Don't have Google Earth™? Install now.
After downloading, run the Executable File (.exe) and follow the screen instructions. Upon finishing the installation, restart your computer.
Open your CAD software. CAD-Earth should appear in the toolbar or ribbon. It will also show as a shortcut on your Windows desktop.
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.
Using a specialized tower crane foundation design XLS template provides several advantages over manual calculations:
A professional Excel calculation sheet must be clean, transparent, and easy to audit by third-party checkers. It should avoid hidden formulas and follow a logical top-to-bottom flow. Section 1: Project Metadata Project Name / Location Crane Model and Manufacturer Designer and Checker Names Design Code Selected (e.g., ACI 318-19, EN 1992) Section 2: Input Parameters (Color-Coded Cells)
For weak soils, a pad foundation won’t work. The XLS should toggle to "Pile Cap Mode," calculating pile forces, pile group efficiency, and cap bending between piles.
Based on the soil pressure distribution, the XLS calculates the required steel area (As) in both directions. Tower Crane Foundation Design Xls
Engineering spreadsheets must be calibrated to specific localized or international design codes to pass regulatory peer reviews:
However, a spreadsheet is only as good as the inputs it receives. Garbage in equals garbage out—or worse, a collapsed crane.

Most professional-grade tower crane foundation spreadsheets include the following core components:
Eliminates the need for a separate reusable chassis, utilizing the building's structural mass. The XLS should toggle to "Pile Cap Mode,"

Using spreadsheets for this critical design task has clear strengths and limitations. Understanding these is key to using them effectively.
From a practical example:
For example, a 6m × 6m × 1.5m foundation with concrete density 24 kN/m³ yields:
The final output of a well-designed spreadsheet is not just a set of numbers, but a comprehensive, auditable design report . This report is a crucial project document, serving as a record of the calculations and verifying compliance. All inputs, intermediate values, and final checks should be clearly displayed.
