The invention provides a CAD (computer-aided design) drawing information batch processing method based on ObjectArx. The CAD drawing information batch processing method comprises the following steps: opening a CAD drawing, storing a polyline entity ID (identity) according with feature drawing frame features into a TKAarray array, judging whether CTKInfo is attached to the feature drawing frame in the TKAarray array, if so, not adding, and otherwise, adding CTKInfo to the feature drawing frame; ordering the TKAarray array according to an X coordinate of a polyline angle point so as to arrange page numbers according to the order; orderly reading drawing information items in a chart-information list box, filling into the CTKInfo of the feature drawing frame in the opened CAD drawing, and adding related label information to a preset position according to the preset Scale. According to the invention, the CTKInfo is customized by expanding a CAD object; the drawing information batch processing function is achieved; the functions such as drawing information batch filling, compiling, labeling and automatic arranging of the drawing page number are included, and the CAD drawing information batch processing method has the characteristics of good modularity, strong independence, simple connection, use convenience and efficient internal function, strong code reusability and the like.
