【讨论】【灌水】Firstly,research Exploding entity type for AutoCAD2002
 

Some entities can be exploded, or decomposed, into a set of simpler elements. The specific behavior depends on the class. For example, boxes can be exploded into regions, then lines. Polylines can be exploded into line segments. An mtext entity can be exploded into a separate text entity for each line of the original object. An mline entity can be exploded into individual lines. When you explode a block reference, AutoCAD copies all entities in the block reference and then splits them into their components.

To meet the requirement of high precise of product and execute the new GPS, in my view, the third development plan based on AutoCAD software should be canceled.
There are several reasons for what as follows:
1)
On the view of the above table, that aren't exploded such Entities as AcDbRay,AcDbXline,AcDbSpline,AcDbXline,AcDbMline.
In AutoCAD 2002 software, the complex curve is not expressed.

2)
AcDbDimension object involves many objects such as solids,lines,text,strings,point.
To third developing Partner, it is difficult to extract all of the characteristics of AcDbDimension object.
3)..........................
