Nếu bạn sử dụng hoặc kế hoạch sử dụng BOMs, PDM, hoặc ghi chú liên quan trên bản vẽ, sau đó bạn cần phải thực hiện Nếu bạn thực hiện rất nhiều bạn tình, điều quan trọng là phải có một nhịp điệu hiệu quả khi làm việc với giao diện. Cách hiệu quả nhất để sử dụng giao diện Mate là như sau: | Part II Building Intelligence into Your Parts FIGURE The Equations interface Using the Equations interface you can turn off equations temporarily by deselecting the Active check box in front of the equation. Equations can also be deactivated by a design table. I will discuss design tables in more detail in Chapter 10 which discusses configurations. Although I do not cover configurations until Chapter 10 I will mention this here. Equations and configurations particularly those that are driven by a design table should probably not be mixed. This is not because they do not work together but more for the sake of organization. When controlling dimensions it can become confusing if the changes are being driven from multiple sources. Also there is no reason not to bring your equations into Excel rather than using the comparatively limited equation functionality offered by SolidWorks. Creating equations Equations are easy to create and useful for many purposes. A common situation where you would use an equation is to space a pattern of holes evenly along an edge including the gap on both ends where the gap at the ends is half of the regular spacing. Before you write an equation you need to take care of a few organizational details. Naming dimensions It is not necessary to name every entity in every SolidWorks document but you should get in the habit of naming important features sketches and even dimensions. Dimensions become particularly important when you use equations configurations and design tables. Under most circumstances you do not use or even see dimension names but with equations you do. 304 Using Equations 9 Named dimensions make a huge difference when you want to recognize the function of an equation by simply reading it. A most obvious example would be the difference between D3@Sketch6 and Length@WindowExtrusionSketch. The first name means nothing but the second one is descriptive if you are familiar with the part.
