You can edit both hatch boundaries and hatch patterns. If you edit the boundary of an associative hatch, the pattern is updated as long as the editing results in a valid boundary. Associative hatches are updated even if they're on layers that are turned off. You can modify hatch patterns or choose a new pattern for an existing hatch, but associativity can only be set when a hatch is created. You can check to see if a Hatch object is associative by using the Associative property.
用户可以编辑图案填充边界和填充图案。如果编辑关联图案填充的边界，只要编辑的结果是有效的边界，图案就会被更新。即使关联图案填充位于已关闭的图层上，仍将对其进行更新。用户可以修改填充图案或为现有的图案填充选择新的图案，但是只能在创建图案填充时设置关联性。可以使用 Associative 特性查看 Hatch 对象是否具有关联性。
You must re-evaluate a hatch using the EvaluateHatch method to see any edits to the hatch.
必须使用 EvaluateHatch 方法重新计算图案填充才能看到任何图案填充的编辑效果。
For more information about editing hatches, see “Modify Hatches and Solid-Filled Areas” in the AutoCAD User's Guide.
