solidworks概念設計云入門教程之無參直接建模

寂靜天花板

When I was first exposed to parametric CAD in 1995, I immediately saw the promise this modeling technique offered.  No more add, subtract, union Boolean operations.  No more user coordinate systems just to sketch some geometry.
Coming from a manufacturing background, I quickly became comfortable defining some stock material, and then refining it using parametric features.  Sure, under the hood I was still doing Boolean modeling, but it sure seemed faster, easier and much more fun. Finally, software that thought the way I did!
95年剛接觸參數化CAD時，那個爽。

二十年過去了，雖然還是著迷于參數化建模，可也有恐懼的感覺，特別是后期修改需要有出人意料的設計變更時。歷史化建模已經被證明是很有用的，可它也有局限性。
把這兩種方法結合在一起，用戶可以充分利用每種方法的優勢之處。當然直接建模也可以用于修改外來導入的不帶任何參數化特征數據的情況，云解決方案把兩種建模方式無縫結合在一個單一的建模環境中，讓你兩全其美。

The single modeling environment allows users to build models using a parametric, history-based approach combined with the flexibility of direct editing (where you push and pull features). Unlike other solutions, these two methods can be mixed in a single model, providing rapid development without sacrificing model intelligence.
單建模環境允許用戶建立用參數化，基于歷史記錄的方法結合直接編輯的靈活性（如您的推拉功能）車型。不像其他的解決方案，這兩種方式可以混合在一個單一的模式，提供快速的發展，而不犧牲模型情報。
