Constrained Surface
Create a surface from a selection of points or mesh data within a specified tolerance. Display deviations and optimize for performance or smoothness.
与编织布类似,每个曲面大致都是矩形。曲面有三个方向:U、V 和法向。边界曲面剖面 U 和 V 分别代表曲面的 X 和 Y 方向。


- 单击
。
- Choose to define the surface by points or mesh data.
- Points - Select the vertices to define the surface. The surface is created Normal to the selected vertex. To change the orientation of the surface, click the vertex in the dialog to show additional options:
- Click in the Normal field to select it, then select the direction in which to create the surface from the model.
- Click the Mate connector button to select a mate connector.
- Click the Flip normal button to switch the orientation.
- Mesh - Select the mesh bodies or faces to define the surface.
- Points - Select the vertices to define the surface. The surface is created Normal to the selected vertex. To change the orientation of the surface, click the vertex in the dialog to show additional options:
- Set the Tolerance to allow when creating the surface. The larger the tolerance, the simpler and larger the resulting surface.
- Click the Optimize dropdown and select to optimize for smoothness or performance.
- Smoothness - Typically produces higher-quality surfaces with lower curvatures, but with slower performance and more control points.
- Performance - Faster performance that may produce lower-quality surfaces.
- Click the Deviation check box to view the maximum deviation between the original points/mesh and the created surface.
- Click the Show deviation check box to display the Maximum deviation or All deviations on the model.
- Set the Limit for deviations to display. Any deviations below the entered limit will not be displayed on the model.

这列出了曲面特征工具的集合。这不是一份详尽的清单。对曲面建模时可以使用其他特征工具。有关其他信息,请参阅曲面。
-
加厚 - 增加曲面的深度。通过赋予曲面厚度并将其转换为实体、在现有零件或曲面中添加或移除材料,或者在其路径中与零件相交来创建新零件或修改现有零件。
-
闭合 -通过选择空白空间周围的所有边界来创建零件以形成实体。使用任何一组相互相交或在边界处连接的曲面和实体(包括平面和面)来创建体积。通过添加、移除或交叉零件来创建新零件或修改现有零件。
-
圆角 - 使尖锐的内部和外部边变圆,并通过选择“边圆角”定义为标准固定半径、或更样式化的圆锥或变量。或者,可选择应用全圆角,以在两条相对边之间创建一个或多个面的无缝融合。
-
面混合 - 圆滑化锐化连接或不相连的内部和外部面,以在面之间创建无缝混合,或者分离混合以创建新面,定义半径或恒定宽度。进一步定义混合横截面(滚球或扫掠轮廓)、对称性、控制、修剪、约束和界限。
-
删除面 - 从零件中移除几何图元。选择是否修复周围的面(通过延伸面,直到它们相交)、封口空心或保持空心开放。如果没有零件的参数化历史记录(导入的零件常常出现这种情况),此直接编辑工具特别方便。
-
移动面 - 平移、旋转或偏移一个或多个选定面。如果没有零件的参数化历史记录(导入的零件常常出现这种情况),此直接编辑工具特别方便。
-
替换面 - 修剪面或将面延伸到新曲面。如果没有零件的参数化历史记录(导入的零件常常出现这种情况),此直接编辑工具特别方便。
-
偏移曲面 - 通过偏移现有面、曲面或草图面域创建新曲面。将偏移距离设置为 0 可在原位创建一个副本。
-
边界曲面 - 创建或添加由其边界轮廓指定的曲面。
-
填充 - 通过定义边界创建曲面(或从曲面创建零件),并使用边界条件优化曲面(而非要求使用参考曲面)。
-
移动边界 - 移动曲面的边界边以对其进行延伸或修剪。
-
直纹曲面 - 从草图区域的现有边或多条边创建新的或额外的直纹曲面。
-
相互修剪 - 通过延伸交点来修剪两个相邻的曲面以完成修剪。
-
Constrained surface - Create a surface from a selection of points or mesh data within a specified tolerance. Display deviations and optimize for performance or smoothness.

iOS and Android support for the Constrained surface feature is limited to displaying and editing existing surfaces. Constrained surfaces can only be created on the desktop (browser) platform. They cannot be created on iOS or Android platforms.
