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.

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!: d1 E6 w, C- q3 H5 y, O0 c- w

Fast forward 20 years, I’m still a huge parametric modeling fan, but I’ve also encountered that feeling of dread when a late change to a model requires dramatic design alterations. History-free editing has proven useful in these types of situations, however, it also has limitations.

Of course, direct editing is also very useful for modifying imported solid geometry that does not include any parametric feature data. Fortunately, SOLIDWORKS 3DEXPERIENCE solutions combine both parametric and direct editing into a seamless, single modeling environment, giving you the best of both worlds!! |7 y/ D, O. _9 |) |
二十年过去了，虽然还是着迷于参数化建模，可也有恐惧的感觉，特别是后期修改需要有出人意料的设计变更时。历史化建模已经被证明是很有用的，可它也有局限性。

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.
