Let’s be direct. You cannot buy a new license for CivilCAD 2008 in 2025. Domussoft (now part of Diehl Group) has moved on to CivilCAD 2024, which only supports AutoCAD 2020-2025.
If you are searching for CivilCAD 2008 para AutoCAD 2010 64 bits because you have an original dongle (hardlock) – good news: The 64-bit patch supports the parallel port and USB dongles. Bad news: No driver support for modern USB 3.0 ports. Use a USB 2.0 hub.
If you do not have a license, please note that using cracked versions for production work is risky. Crashes, data corruption, and malware are common.
To make CivilCAD 2008 sing on AutoCAD 2010 64-bit, adjust these system variables: civilcad 2008 para autocad 2010 64 bits
This is the most common query: "I have CivilCAD 2008. Will it install on my 64-bit AutoCAD 2010?"
The short answer is Yes, with caveats.
| Component | Status | Notes | | :--- | :--- | :--- | | CivilCAD 2008 Core | Partial | The main ARX (AutoCAD Runtime eXtension) files for 64-bit were released late. Ensure you have CivilCAD 2008 build 08.00.06 or higher. | | 2D Tools (Plans, Sections) | Full | Lines, hatches, dimensions, and annotations work flawlessly. | | Terrain Model (MDT) | Full | Creating grids, contours, and profiles works natively. | | Sewer & Hydraulic networks | Full | Calculation engines run as 64-bit processes. | | LISP Routines | Full | Custom scripts run faster. | | 3D Visualization | Partial | Some old OpenGL calls may flicker; use DirectX 9 mode in AutoCAD. | Let’s be direct
Crucial Warning: CivilCAD 2008 was released before AutoCAD 2010. The official 64-bit compatibility patch came via a hotfix from the developer (Domussoft/Diehl). Without that hotfix, the installer will block you, stating: "CivilCAD requires AutoCAD 2007-2009."
A few advanced users attempted unofficial hacks. None are recommended for production environments, but they illustrate the technical depth of the problem.
Why are users clinging to this 2008/2010 combo instead of moving to CivilCAD 2024? However, if you are starting a new project
However, if you are starting a new project today, consider:
Released in 2007–2008, CivilCAD 2008 was optimized for AutoCAD 2008 (32-bit). Its key features:
CivilCAD 2008 was distributed as ARX (AutoCAD Runtime eXtension) and CUI (Custom User Interface) files, tightly coupled to AutoCAD 2008’s specific API (ObjectARX 2008). It relied on the acad.exe memory model – a hard 32-bit address space.
CivilCAD 2008 often called third-party 32-bit DLLs for:
On a 64-bit system, even if you forced AutoCAD 2010 64-bit to run, those external dependencies would fail to load.
