Summary
Returns all coordinate, original dimension and text string (comment, designator, free) objects whose Text Height property complies with the Query.
Syntax
TextHeight : 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(TextHeight) : Number– to specify a height in mil.AsMM(TextHeight) : Number– to specify a height in mm.
Example Usage
TextHeight = 60
Returns all coordinate, original dimension and text string (comment, designator, free) objects that have an Text Height property which is 60 current measurement units.
TextHeight >= 1.27
Returns all coordinate, original dimension and text string (comment, designator, free) objects that have an Text Height property which is greater than, or equal to, 1.27 current measurement units.
AsMils(TextHeight) Between 40 And 80
Returns all coordinate, original dimension and text string (comment, designator, free) objects that have an Text Height property which is greater than, or equal to, 40mil and less than, or equal to, 80mil.
AsMM(TextHeight) < 1.778
Returns all coordinate, original dimension and text string (comment, designator, free) objects that have an Text Height property which is less than 1.778mm.
Tips
- The Text Height property is only defined for coordinate, original dimension and text string (comment, designator, free) objects.
