Data Transform Based on ObjectARX from AutoCAD to MAPGIS

MAPGIS and AutoCAD are broad use's system at home and abroad, so the interaction with them is necessary. Data Transform sets up the friend bridge for them, and Data resources become shared with them. The DXF format is transformed in former Data Transform from AutoCAD to MAPGIS, but it only does common entities. For example, Mtext and BlockReference aren't transformed into MAPGIS, So the way lacks the consistency with the primary data. It can't batch the Data from DWG to MPJ. To these problems, a new method is put forward. The developer tool is ObjectARX. All entities of AutoCAD and the parameters of the entities are direct transformed into the point, line and region files. So it can hold the consistency with the primary data. Trough the test, data quantity is about fifty percent of the former, and it holds the consistency with the primary data.
