I am trying to draw a line in 3D space,   however with the following code:

  
  BaseObject *op = doc->GetActiveObject();  
  if (!op) return TOOLDRAW_0;  
  
  bd->SetMatrix_Matrix(NULL, Matrix());  
  
  bd->SetPen(Vector(1,0,1));  
    
  Vector position = op->GetRelPos();  
  
  bd->DrawLine2D(position, position + (0,   0,   600));  
  bd->DrawLine2D(position, position + (0,   600, 0));  
  bd->DrawLine2D(position, position + (600, 0,   0));  
  
    
  return TOOLDRAW_HANDLES;  

I get a line being drawn across the view port instead of in 3d space.   I thought that DrawLine() replaced Line3D()?   Am I doing something wrong?

You are showing DrawLine2D() instead of DrawLine() in your code.  DrawLine2D() only draws in Screen space (2D).

Remember that the DrawLine() coordinates must be in World space (not local - which is what GetRelPos() retrieves!).  You would be better served using:

Vector position = op->GetMg().off;
