Attachment and AssociativityKeyCreator Drafting / Detail / Detail Overview / Attachment and AssociativityBefore adding detailing to your designs, it will be important to understand the following regarding detail attachment and associativity:
Dimension Attachment:Attachment is determined by the integrity of a dimension’s connection to an entity. A dimension based off of, or positioned from, geometric positions on an entity is an attached dimension. For instance, a dimension attached to two endpoints of a line is an attached dimension. A dimension whose positions are cursor selected, or placed using key-in, is un-attached.
Dimension Associativity:A dimension is non-associative if the program cannot determine its value, or if any entity required to determine its value is deleted. For instance, a dimension whose value is accurate and updates in accordance to changes made to the entity to which it is attached is considered an "associative" dimension. As a result, dimensions’ whose values have been manually applied or modified are not associative. NOTE: All non-associative dimensions are also un-attached. |
