I am importing data from a dxf (drawing exchange format) file into a table. What is the best way to search for the lines I need then put them into a table. I must first find the "ENTITIES" section then look for either a "LINE", "CIRCLE", or an "ARC" entitie. Then I must read each line and evaluate what to do with the next line based on what the value is. For example the following is the description of a line that I would put in a table by extracting the needed data. The 5 means handle the 8 means layer name etc.

LINE
5
35
100
AcDbEntity
8

AcDbLine
