class OdDbScale : public OdDbObject;

Description

This class implements the scale object that stores information about an annotation scale as an element of the database container. The database stores the scale instances in the dictionary and associates the object ID with an each scale instance. The scale dictionary is accessed from the database object using the getScaleListDictionaryId() method. The root drawing dictionary, associates the "ACAD_SCALELIST" name with the scale dictionary.

Remarks

This class is intended for stand-alone applications only. TXSDK developers cannot use it.

	setDrawingUnits	Sets the number of drawing units as a positive Double value. The initial value is 1.0 by default.
	setIsTemporaryScale	Sets the scale temporary status as a Boolean value. The initial value is False by default.
	setIsUnitScale	Sets the scale default status as a Boolean value. The initial value is False by default.
	setPaperUnits	Sets the number of paper units as a positive Double value. The initial value is 1.0 by default.
	setScaleName	Sets the internal scale name as a String value. This name is used as a comment for the ratio of paper units to drawing units when the scale object is displayed in a list. The initial value is an empty string by default.
