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. Non-associative dimension points can be useful if you want to dimension a component not represented by an AEC object, like a property line, or AutoCAD objects like blocks.
Note: You can specify if manual dimension points near custom objects can be associative or non-associative.
