Associative Dimensions in Sections/Elevations/IE and 3D Document
Dimensions in the Section/Elevation/IE and 3D Document windows are associative, meaning that every dimension point you create adheres to its reference point. For instance, when you stretch the Window in the wall, it will cause the entire dimension chain to be automatically updated.
Elevation Dimensions and Angle Dimensions are also associative.
When a Model type Section is turned into a Drawing type Section, dimension points will still remain associated to the right points and will reflect the changes to the model, if you use the Rebuild from Model command.
