You can create associative or nonassociative hatches. Associative hatches are linked to their boundaries and updated when the boundaries are modified. Nonassociative hatches are independent of their boundaries.
用户可以创建关联的或非关联的图案填充。关联的图案填充链接到它们的边界并且会在边界改变时自动更新，而非关联的图案填充则独立于它们的边界。
To make a hatch associative, set the Associative property of the hatch object created to TRUE. To make a hatch nonassociative, set the Associative property to FALSE.
若要使一个图案填充具胡关联性，可以设置创建的 hatch 对象的 Associative 属性为 TRUE。若要使 hatch 不具有关联性，则设置 Associative 属性为False。
Associativity for hatch must be set before appending the hatch loop. If a hatch object is nonassociative, you can make it associative again by setting the Associative property to TRUE and reappending the hatch loop.
hatch 关联性必须在添加填充环前设置。如果 Hatch 对象是非关联性的，那么可以通过设置 Associative 属性为 TRUE 让其再次关联然后添加填充环。
