change the length of extension lines. You can also move individual dimension

AutoCAD Architecture offers several methods for editing AEC Dimensions:
■ You can directly edit AEC dimensions using grips.
■ You can change AEC dimension settings on the Properties palette.
■ You can select editing commands from the context menu for the selected
AEC dimension.
Adding Points to an AEC Dimension
You can add points to an AEC dimension in the following ways:
■ You can attach a new object to the dimension; if dimension points have
been defined for that object type in the dimension style, corresponding
associative points are added to the dimension.
■ You can add associative points to the dimension by picking base points
or OSNAP points on AEC objects.
■ You can add non-associative points to the dimension by picking points
selected anywhere in the drawing. These points are not connected to objects
and are therefore not associative. To change their position, you need to
move the location grips generated on the dimension.
When you attach an object for which dimension points have been specified
in the AEC dimension style, the points are dimensioned and added to the
appropriate dimension chains. For example, if you add a wall to an AEC
dimension that has style settings for wall components in 2 chains, component
dimensions are added to these 2 chains.
If an object is not specified in the AEC dimension style, you can either
dimension the base point of the object or pick any of its OSNAP points as
dimension points. These dimension points can be manually offset while
retaining the associativity to the object. For example, you can dimension the
base point of a multi-view block and offset the dimension from the base point.
If the multi-view block is moved or rotated, the dimension moves and rotates
with it while observing the offset.
To add non-associative dimension points in a drawing, you specify points,
which are added as location grips, and are dimensioned on the selected
dimension chain. When the location grip is moved, the dimension point is
