Time:09-20

Just consult everybody, as shown in the figure below for cad graphics,

Now want to comments from graphics data such as Angle and yaw degrees and bolt diameter, think of the way is:
1, converted to DXF file, but the rules cannot extract,
2, AutoCAD to extract data, results such as 1,
3, the use of VB or c # to centre point for identifying the choice of object collection development, now seems more likely, but the difficulties method has the following three points:
1), complete information on how to pick up a ball, will choose the scoping a ball in the area?
2), how to according to the labeling rules extraction Angle?
3), after how to M number (this is the identity of the threaded holes) in accordance with the law of angular dimension to arrange out?
