On Sunday morning, I debugged acad.exe lingering in Task Manager post-shutdown, linked to an NVIDIA driver. Disabling hardware acceleration in AutoCAD/Civil 3D resolved the issue. A clean installation of the driver also fixed the problem, which I confirmed through a newly found knowledge base article on the matter.
The Autodesk University 2026 Thrive Guide by Shaan Hurley offers essential tips for attendees preparing for the event in Las Vegas from September 15-17. The guide includes venue highlights, packing suggestions, and advice on networking and session attendance. It emphasizes the importance of hydration, comfortable footwear, and enjoying the local cuisine and attractions.
The article discusses the differences between the Overlay and Attach methods in AutoCAD and Civil 3D. While Overlay is preferred for managing references, Civil 3D introduces complexities with data shortcuts, creating potential mixed loops that can disrupt project workflows. Users must understand file dependencies to avoid creating loops before referencing drawings.
Why cascading data references and circular loops degrade Civil 3D performance and stability, how to prevent them, and what Autodesk could build to kill the problem.
Shaan has developed a Civil 3D plugin in C#, functioning as an audit tool to analyze AutoCAD drawings efficiently. It captures essential data on references and project health, providing detailed reports and insights. The plugin can run in headless mode, enhancing performance for large batches of drawings. Future enhancements will address sheet set detection and layer audit calibration.
My session "The Stack Inversion Is Real" was accepted for Autodesk University 2026, focusing on AI's impact on CAD management. While I'm disappointed my favorite submissions were declined, this presentation will reflect my current role as a practitioner. Attendees will learn about AI's changes in CAD functions and strategies for evolving expertise.
Managing a Civil 3D shop can lead to complex issues with circular data shortcuts that obscure visibility and hinder performance. Many users unknowingly create tangled reference chains, resulting in file corruption and slow operations. The author seeks insights from other CAD managers on preventing and managing these challenges for better collaboration and efficiency.
Most CAD managers underestimate the significance of Autodesk crash data found in Customer Error Reports (CERs). Regularly analyzing these files reveals underlying issues affecting user environments, often overlooked by support tickets. Cer data can identify patterns leading to crashes and help implement fixes, thereby reducing user frustration and improving productivity.
AutoCAD 2027, released on March 25, 2026, emphasizes AI-assisted workflows, featuring the Autodesk Assistant for enhanced user interaction with DWG files. Key updates include multi-user DWG editing, a Geometry Cleanup tool, improved layout tab switching, and significant upgrades in Civil 3D, especially in drainage tools, enhancing collaboration and efficiency.
Updated 9/6/2026: The PowerShell scripts in this post have been rewritten and tested end to end. The original versions captured the decoder with 2>&1, which fails silently in any PowerShell script that sets $ErrorActionPreference = ‘Stop’: the decoder’s stderr output…
