Nearness
The position of a text element is the position of the lower left corner of the text when viewed as
read. A text element becomes associated with the nearest geometry element within one text
height of the text. The distance between the two elements is measured differently for each
geometric element type, as described in the following sections. An element which is near nothing
is considered an “orphan” and will cause CAD-to-DMC to generate a warning message.
Lines
The distance between a text element and a line element is the minimum distance from the line to
the text. Normally, this is the perpendicular distance between the line and the text (Figure 10,
Case 1). However, if a perpendicular line cannot be drawn between the line and the location
point of the text, the distance is measured from the text to the nearest endpoint of the line
(Figure 10, Case 2).
