Hi,everyone. I have created an AIS_Trihedron for display using the codes below:
Handle_Geom_Axis2Placement aTrihedronAxis=new Geom_Axis2Placement(gp::XOY());
myUCS = new AIS_Trihedron(aTrihedronAxis);
the AIS_Trihedron serve as a "indicator" which telling the user where the local coordinate system is, but when I perform selecting in the AIS context, this AIS_Trihedron can be selected and deleted which is not what I want. Can anybody tell me how to make this AIS_Trihedron unselectable? Thanks!
