OdDbScale Class

Syntax

C++

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.
