Flags Property

Summary

Flags that indicate how to handle exposed areas, and the direction of the shear wave.

Syntax

C++/CLI

Python

public FreeHandShearCommandFlags Flags { get; set; }

public: 
property FreeHandShearCommandFlags Flags { 
   FreeHandShearCommandFlags get(); 
   void set (    FreeHandShearCommandFlags ); 
}

Flags # get and set (FreeHandShearCommand)

Property Value

Values that indicate how to handle exposed areas, and the direction of the shear wave.
