Q: Why did I fail to convert all lines of a line dataset into region objects?
A: There are two reasons for the failure of converting a line object into a region object. The first reason is that the line object is a straight line, and the straight line cannot be converted into a region object. The second reason is that the line object is a compound object. You must split the compound line object and then connect the separate lines segments into a single line before you convert it into a region object.
