Summary
Returns all angular dimension, baseline dimension, datum dimension, linear diameter dimension, and linear dimension objects whose Extension Line Width property complies with the Query.
Syntax
DimensionExtensionLineWidth : 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(DimensionExtensionLineWidth) : Number– to specify a width in mil.AsMM(DimensionExtensionLineWidth) : Number– to specify a width in mm.
Example Usage
DimensionExtensionLineWidth = 10
Returns all angular dimension, baseline dimension, datum dimension, linear diameter dimension, and linear dimension objects that have an Extension Line Width property which is 10 current measurement units.
DimensionExtensionLineWidth >= 0.2286
Returns all angular dimension, baseline dimension, datum dimension, linear diameter dimension, and linear dimension objects that have an Extension Line Width property which is greater than, or equal to, 0.2286 current measurement units.
AsMils(DimensionExtensionLineWidth) Between 8 And 12
Returns all angular dimension, baseline dimension, datum dimension, linear diameter dimension, and linear dimension objects that have an Extension Line Width property which is greater than, or equal to, 8mil and less than, or equal to, 12mil.
AsMM(DimensionExtensionLineWidth) < 0.2794
Returns all angular dimension, baseline dimension, datum dimension, linear diameter dimension, and linear dimension objects that have an Extension Line Width property which is less than 0.2794mm.
Tips
- The Extension Line Width property is only defined for angular dimension, baseline dimension, datum dimension, linear diameter dimension, and linear dimension objects.
- The child objects of angular dimension, baseline dimension, datum dimension, linear diameter dimension, and linear dimension objects returned by the Query, are not returned.
