然而，站在AutoCAD 2025与2026版本的视角回顾，2021版在某些前沿领域存在局限性。三维建模方面，2021版尚未引入后续版本中加速建模与布线的高级Surface工具。性能表现上，尽管二维平移缩放有所优化，但在多图档环境下的支持不如引入“浮动窗口”功能的2022版，在处理超大数据集时的启动与保存速度也逊于经过内核优化的2025与2026版。自动化程度上，2021版的基础自动化依赖于传统的LISP脚本，尚未引入Autodesk AI赋能的“智能块”检测与自动放置功能，后者从2024版才开始真正成熟。

The feature presents a palette listing all previous versions, with filtering options by date range, author, or time increment between saves. You can then invoke the DWG Compare tool to see differences side-by-side – previous versions appear in red, newer versions in green, and unchanged elements in gray. The comparison results can be exported to a new drawing, and objects can be imported from the compared drawing.
