Description
model.result(<pgtag>).create(<ftag>,"Arrow...") creates an arrow plot feature named <ftag>.
Arrow plots are available in 2D and 3D. ArrowPoint plots arrows at points in 2D or 3D. ArrowLine plots arrows on lines in 2D or 3D such as geometry boundaries in 2D or cut plane edges in 3D. ArrowSurface plots arrows on surfaces in 2D or 3D. ArrowVolume plots arrows in a 3D volume.
The following properties are available:
