Furthermore, AutoCAD 2021 continued Autodesk’s strategy of maximizing user value through specialized industry toolsets. Subscribers were not just given a blank geometric canvas; they received access to vertical products like AutoCAD Architecture, AutoCAD Electrical, and AutoCAD MEP (Mechanical, Electrical, and Plumbing). These toolsets provided thousands of intelligent, industry-standard objects and automated functions. For example, the MEP and Architecture toolsets in the 2021 version inherited the native platform's improved revision cloud properties and external reference (Xref) compare capabilities. By unifying these specialized features under a single subscription, Autodesk empowered multidisciplinary teams to operate within a shared foundational ecosystem without sacrificing the highly specific tools required for their respective fields.
: Users can now compare two versions of an external reference (Xref) and implement changes without leaving their current drawing. Blocks Palette

Current note: You cannot buy a new license for AutoCAD 2021 in 2025. However, Autodesk includes the ability to install previous versions with an active subscription. If you have a current subscription, you can still download and activate AutoCAD 2021 legally via the Autodesk Account portal.
虽然“打断于点”听起来是一个相当基础的命令，但其实际应用场景非常广泛：从墙体需要被门洞打断，到一条连续的管线需要分成独立的两段，都是设计中极为常见的需求。AutoCAD 2021 正式引入了“在单个点处打断对象”的命令，能够将元素精确地在该点处一分为二。 For example, the MEP and Architecture toolsets in
