Function Description

Edit Data 选项卡上的Feature Editing组提供了处理line或region的边界线的功能，主要对line或region的边界线进行重采样和平滑处理。

The Feature Editing group on the Edit Data tab provides functionality to process the boundaries of lines or regions, primarily for resampling and smoothing the boundaries of lines or regions.

当line或region的边界线上的节点太多时，可用Resampling按钮对其进行重采样处理，去掉一些节点，同时尽量保持线的形状。

When there are too many nodes on the boundaries of lines or regions, you can use the Resampling button to perform resampling, removing some nodes while trying to maintain the shape of the lines.

• Feature Editing组中的控件只有在map中有选中的可编辑图层中的geometry（line和region）时才可用。
• The controls in the Feature Editing group are only available when there are selected geometries (lines and regions) in editable layers in the map.
• 关于重采样的原理及重采样的结果说明，请参见：线状对象重采样说明。
• For the principles and results of resampling, please refer to: Line Object Resampling Description.
• 参数化曲线（如弧线、free curve、bezier curve、B 样条曲线等）进行重采样时，会先将曲线转为线段，然后对转换线段进行重采样。注：CAD Dataset中，参数化曲线不支持重采样。
• When resampling parametric curves (such as arcs, free curves, Bezier curves, B-spline curves, etc.), the curves are first converted to line segments, and then the converted line segments are resampled. Note: In CAD Datasets, parametric curves do not support resampling.

Operational Instructions

1. 将map中要进行重采样的geometry（line或region）所在的layer settings为可编辑状态。
2. Set the layer containing the geometry (line or region) to be resampled in the map to an editable state.
3. 选中要进行重采样的geometry（line或region），可以同时按住 Shift 或者 Ctrl 键，连续选中多个geometry。
4. Select the geometry (line or region) to be resampled; you can hold down the Shift or Ctrl key to select multiple geometries continuously.
5. 在Edit Data 选项卡的General editing下拉菜单中，单击Trimming分组中的Resampling按钮，弹出Resampling Settings对话框。
6. In the General editing drop-down menu on the Edit Data tab, click the Resampling button in the Trimming group to pop up the Resampling Settings dialog box.
7. 在resampling method的下拉框中，选择合适的resampling method，并在采样容限右侧的文本框中输入容限值，默认值为0.4，应用该方法对line或region进行重采样。
8. In the drop-down box for the resampling method, select an appropriate resampling method, and enter the tolerance value in the text box to the right of Sampling Tolerance, with a default value of 0.4, then apply this method to resample the lines or regions.
9. 要重采样map中其他图层中的geometry，重复上面第 1 步到第 4 步的操作。
10. To resample geometry in other layers in the map, repeat steps 1 to 4 above.
11. 单击OK按钮，对选中的geometry进行重采样操作。
12. Click the OK button to perform the resampling operation on the selected geometry.

Note:

当启动了multi-layer editing时，用户可以同时选中多个可编辑图层中的多个line和region来进行重采样操作。

When multi-layer editing is enabled, users can select multiple lines and regions from multiple editable layers simultaneously to perform resampling operations.
