I tried to enable and disable safe frame by code, but I didn’t find any method property in .Net sdk to do that, I only found a property Rhino.Render.Utilities.SafeFrameEnabled but it has no setter.
Anyone knows how to disable the Safe Frame by code?
The only reference I can find in the C++ SDK is also not settable:
/** Queries whether or not the Safe Frame is visible.
\return \e true if visible, else \e false. */
RHRDK_SDK bool RhRdkIsSafeFrameVisible(CRhinoDoc* pDoc = ::RhinoApp().ActiveDoc());
