Q: Why did I fail to convert points to line with SuperMap iDesktop 8C?

A: First, the associated field should be of numeric, text, or wide char type in the conversion process. Next, if the values of the join field of all point objects of the point dataset are null, or are a unique value, the conversion will fail. The conversion will also fail if some of the values of the join field of all point objects of the point dataset are null, and the other values are a unique value.
