The postprocessor supplies additional AutoCAD elements into the input .DXF file. Since it is a sequential processor, all geometry elements MUST be connected to each other. This is done because a machine tool travels from the end of one element (current position) to the start of the next position (goto position). "Connecting the Dots" means that everywhere a geometric "GAP" in the sequential AutoCAD data occurs a line element is developed. This line element bridges the GAP between the end of the last element to the start of the next element. This behavior is commonly known as INDEXING from one element to the next.
This additional line element will affect the processing of the AutoCAD .DXF file. When defining text statements at locations that are at the beginning or end of geometries that are not physically connected, remember the following:
The postprocessor develops a line between all geometries that have a physical gap. This developed line is the same type of line element as though it was developed in AutoCAD. Any text that appears at the beginning or end of this developed line will appear in the NC code according to the rules outlined above. That is, a text statement will be collected and then output when a physical element (such as a line) is encountered.
