Is the program actually entering the 'else' section?? Maybe tbnIniciar->Down is always true? If you're not sure then throw in a print statement to see if anything prints in that section.The RemoveActor function is the correct one to use. I am using that in the program that I'm working on at the moment.If that is not the problem, then it could be that something is still using the actor that you're trying to remove. That can be a problem when using the Delete function to remove it from memory, however I'm not sure if it can be a problem for RemoveActor as well.Hope that helps a bit,Cameron.

Hello All, 
How do I remove an individual actor from the scene? My code does not work. Someone help me? Thanks. if  (tbnIniciar->Down) {  VTK3->GetRenderer()->AddActor(outlineActor);  } else {    VTK3->GetRenderer()->RemoveActor(outlineActor);    VTK3->GetRenderer()->RemoveViewProp(outlineActor);    VTK3->GetRenderer()->Clear();   } VTK3->Invalidate();
