New NX Sketch

Beginning with version 1926, NX Sketch has a new solver to help you create sketches that are accurate and represent your design intent.
You focus on creating curves and dimensions to define your sketch.
Accuracy and interpretation

The ≈ symbol shows where dimensions are approximate, for example, after you arbitrarily drag a curve.
Shaded areas assure you that your sketch boundaries are connected.
Potentially distracting information is displayed only when you need it.

Minimized external relationships

Dimensions do not create “P” expressions by default. This minimizes the number of external links to the sketch. When you want to create an external expression, right-click and choose Add/Remove Expression.
Creating fewer external expressions minimizes the chance of changing a sketch expression by mistake and reduces clutter in the Expressions dialog box.
Sketch does not create external geometric relationships by default. When you want to use an external curve, edge, or datum in a sketch, choose the new Include command, or set the Selection Scope so that you can select objects outside of the sketch.

InteractionThe new intelligent solver works in the background as you sketch. Dimensions and relations capture your design intent. The sketch now uses relations instead of geometric constraints. You can create persistent relations, but you will find that you don’t often need to, because most relations are found “on the fly.” Persistent relations you create and the found relations work together.
To create dimensions, you don’t need to use a command. Just select the curve or curves to dimension and select from the candidate preview dimensions you want to create.
Sketch curves change color to black when they are no longer movable, and the Status line tells you your sketch is fully defined.

EditingEdit your sketch by dragging. Select a curve and drag a handle. While editing, click on relations to relax them if they are not what you want. Select a dimension and change the value or drag either arrowhead.
You have freedom to change your design intent, even when the sketch is fully defined, or over-defined. NX sketch guides you to either select specific relations to relax, or you can allow the solver to relax either the needed dimensions or relations to test alternate solutions.

Using existing sketchesWhen you open an existing sketch, you can either edit parameters to make dimensional changes, or you can renew the sketch to take advantage of the new capabilities. Dimensions are the same as before, and constraints are converted into persistent relations.

新建NX草图

从1926版开始，NX Sketch有一个新的解算器，可以帮助您创建精确的草图并表示您的设计意图。

重点是创建曲线和尺寸以定义草图。

准确性和解释

约≈符号显示尺寸的近似位置，例如，在任意拖动曲线后。

着色区域确保草图边界已连接。

潜在的分散注意力的信息只在您需要时显示。

最小化外部关系

默认情况下，标注不创建“P”表达式。这将最小化到草图的外部链接的数量。如果要创建外部表达式，请右键单击并选择“添加/删除表达式”。

创建较少的外部表达式可最大限度地减少错误更改草图表达式的可能性，并减少“表达式”对话框中的混乱。

默认情况下，草图不创建外部几何关系。如果要在草图中使用外部曲线、边或基准，请选择“新包含”命令，或设置选择范围，以便可以选择草图外部的对象。

相互作用

当您绘制草图时，新的智能解算器将在后台工作。尺寸和关系捕获了您的设计意图。草图现在使用关系而不是几何约束。你可以创建持久的关系，但是你会发现你并不经常需要这样做，因为大多数关系都是“动态”的，你创建的持久关系和找到的关系一起工作。

要创建标注，不需要使用命令。只需选择要标注的曲线，然后从要创建的候选预览尺寸中选择。

当草图曲线不再可移动时，其颜色将变为黑色，状态行将告诉您草图已完全定义。

编辑

通过拖动编辑草图。选择曲线并拖动控制柄。编辑时，如果关系不是您想要的，请单击关系以使其松弛。选择一个尺寸标注并更改值或拖动任一箭头。

即使草图已完全定义或过度定义，也可以自由更改设计意图。NX草图将引导您选择要松弛的特定关系，也可以允许解算器松弛所需的尺寸或关系以测试替代解决方案。

使用现有草图

打开现有草图时，可以编辑参数进行尺寸更改，也可以更新草图以利用新功能。维度与以前相同，约束将转换为持久关系。
