You may need to change the associativity of dimensions in several circumstances including adding associativity to dimensions created in previous releases.
You may need to change the associativity of dimensions in several circumstances such as the following:
With DIMREASSOCIATE, you can select one or more dimensions and step through the extension-line origin points of each dimension. For each extension-line origin point, you can specify a new association point on a geometric object. Association points determine the attachment of extension lines to locations on geometric objects.
When you create or modify associative dimensions, it is important to locate their association points carefully so that if you make a future design change, the geometric objects that you change will also change the dimensions associated with them.
When you use the DIMREASSOCIATE command, a marker is displayed that indicates whether each successive extension line origin point of the dimension is associative or nonassociative. A square with an X in it means that the point is associated with a location on an object, while an X without the square means that the point is not associated with an object. Use an object snap to specify the new association for the extension-line origin point or press Enter to skip to the next extension-line origin point.
The marker disappears if you pan or zoom.
You can change all the non-associative dimensions in a drawing to associative. Select all non-associative dimensions, and then use DIMREASSOCIATE to step through the dimensions, associating each one with locations on geometric objects.
You can change all associative dimensions in a drawing to nonassociative dimensions. Select all associative dimensions, and then use DIMREASSOCIATE to convert them into nonassociative dimensions.
