Global Axes
Global Axes, sometimes also called global frame, display orientation of the world. All objects are positioned and oriented relative to these global axes.
3D navigation using rotation or pan, on the other hand, changes only the point of view.
Visibility of the global frame is accessed at runtime via context menu of the control. Programmatically it is manipulated using the ShowGlobalAxes control property or the component context as described below
Global axes can also be viewed as a 3D icon at the left bottom corner of DGKC window. This icon is independent of the normal global axes
Appearance of global axes or the icon can be modified via the relevant IContext_DG interface. See below for details
Global Axes
To obtain access to properties of the global axes, query DGKC>GetView()>
IView_DG>
GetExtendedProperties() > IDictionary_DG >
GetInterface("GlobalAxes") >
IContext_DG
Global Axes Icon
IContext_DG interface for the icon can be acquired via:
DGKC>GetView()>IView_DG>GetExtendedProperties() > IDictionary_DG > GetInterface("GlobalAxesIcon") > IContext_DG
To show/hide the icon call: IContext_DG>SetBool(0), or use the Boolean property id=19 of the DGKC context:
DGKC > GetView() > IView_DG > IView_DG.GetExtendedProperties() > IDictionary_DG > SetBool(19)
Properties
Size and face name of the font used to display axes names can be modified via IFont_DG queried from the IContext_DG.
The double properties below are adjustment factors applied to the automatically calculated dimension, not the actual dimensions.
