Crashes, Clues, and Two Big Wins From Autodesk CER Files

In recent months, CAD stations faced significant issues such as crashes and slow performance, primarily revealed through Autodesk's CER data. Ignored by users, CER files provide crucial insights into system failures. Two major problems were identified and resolved by analyzing these files, underscoring their value in managing CAD software effectively.

Preparing for Autodesk’s 2026 Licensing Changes

Autodesk sent another round of renewal notices this week. More increases. Fewer discounts. And another reminder that network or multi user licensing is almost gone. None of this is new, but the pattern is getting harder to ignore. “We’re committed…

Convert Civil 3D Files for AutoCAD and More

This blog post explains how to convert Autodesk Civil 3D drawings for users with basic AutoCAD or older versions. Key methods include using EXPORTC3DDRAWING for simple output, ETRANSMIT for complete project packages, and EXPORTTOAUTOCAD for quick 2D views. These techniques ensure compatibility and prevent issues with missing geometry.

Floating Point, Multi Core, and Why Precision Still Matters

The importance of precision in CAD software like AutoCAD is highlighted, illustrating how floating point limits affect geometry at large scales. While multi-core processing exists, certain tasks must remain single-threaded to ensure accuracy and reliability. AutoCAD balances threading where beneficial, continually addressing tradeoffs between precision and performance for user stability and productivity.

Fix Common Geometry Issues with MAPCLEAN

MAPCLEAN is a powerful command in AutoCAD Map 3D and Autodesk Civil 3D that addresses common geometry issues like duplicates, overshoots, and bad intersections from various sources. Its simple workflow allows users to select objects and choose specific cleanup actions, ensuring clean geometry for improved design efficiency. Despite its benefits, it's absent in core AutoCAD.
