Dimension Style

The Dimension Style (DSTYLE) attribute, combined with DTANG, controls the overall dimension style. Possible settings are:

DSTYLE DIMLINE

DSTYLE LEADERLINE

DSTYLE EXTERNAL

The default setting of DSTY is DIMLINE. The style displays a radial dimension line with terminators. For DFLAG DIAM this is drawn across the diameter with two terminators; for DFLAG RADI this is drawn from the centre to the circumference with a single terminator. If the dimension text lies inside the circumference, then the dimension line is gapped if the text crosses it. The position of dimension text is controlled by the Dimension Text Offset (DTOFF) attribute.

The dimension line is extended beyond the circumference of the object dimensioned if the text radial position (DTRAD attribute) lies outside the circumference. If the text is horizontal, then a horizontal line is drawn from the radial dimension line to the actual text position. Whatever the text orientation, the line is extended to underline the text if indicated by the DTUL attribute.
