Summary
Returns all angular dimension, baseline dimension, datum dimension, leader dimension, linear diameter dimension, linear dimension, radial diameter dimension, and radial dimension objects whose Dimension Text Gap property complies with the Query.
Syntax
DimensionTextGap : Number
Number will follow the measurement units currently employed for the document – either Imperial (mil; 1mil = 0.001inch) or Metric (mm; 1mm = 0.001meter).
A specific option for the measurement unit can be specified – overriding the default units specified at the document level – through use of an additional measurement unit-based keyword:
AsMils(DimensionTextGap) : Number– to specify a gap in mil.AsMM(DimensionTextGap) : Number– to specify a gap in mm.
Example Usage
DimensionTextGap = 10
Returns all angular dimension, baseline dimension, datum dimension, leader dimension, linear diameter dimension, linear dimension, radial diameter dimension, and radial dimension objects that have an Dimension Text Gap property which is 10 current measurement units.
DimensionTextGap >= 0.2286
Returns all angular dimension, baseline dimension, datum dimension, leader dimension, linear diameter dimension, linear dimension, radial diameter dimension, and radial dimension objects that have an Dimension Text Gap property which is greater than, or equal to, 0.2286 current measurement units.
AsMils(DimensionTextGap) Between 8 And 12
Returns all angular dimension, baseline dimension, datum dimension, leader dimension, linear diameter dimension, linear dimension, radial diameter dimension, and radial dimension objects that have an Dimension Text Gap property which is greater than, or equal to, 8mil and less than, or equal to, 12mil.
AsMM(DimensionTextGap) < 0.2794
Returns all angular dimension, baseline dimension, datum dimension, leader dimension, linear diameter dimension, linear dimension, radial diameter dimension, and radial dimension objects that have an Dimension Text Gap property which is less than 0.2794mm.
Tips
- The Dimension Text Gap property is only defined for angular dimension, baseline dimension, datum dimension, leader dimension, linear diameter dimension, linear dimension, radial diameter dimension, and radial dimension objects.
- The child objects of angular dimension, baseline dimension, datum dimension, leader dimension, linear diameter dimension, linear dimension, radial diameter dimension, and radial dimension objects returned by the Query, are not returned.
