You can create non-associative dimensions from points you pick anywhere in the drawing. For each point you pick, a location point is generated and dimensioned. If the point is used to dimension an object, and the object is moved, the non-associative point is not updated. You have to manually move the non-associative point to reflect the change.
Non-associative grip points on AEC dimension
You can convert AutoCAD dimensions to non-associative AEC dimensions. The AutoCAD dimension points are converted to location points on the AEC dimension.
