Remove insertion grip point using overrule                         By Adam Nagy
If you think that the insertion grip point of a block reference is in the way then you can use GripOverrule to remove it.
The following sample only removes the insertion grip point of dynamic block references:

1. using System;
   
2. using Autodesk.AutoCAD.Runtime;
   
3. using Autodesk.AutoCAD.DatabaseServices;
   
4. using Autodesk.AutoCAD.Geometry;
   
5. 
   
6. namespace ClassLibrary1
   
7. {
   
8.   public class Commands
   
9.   {
   
10.     public class MyGripOverrule : GripOverrule
    
11.     {
    
12.       public override void GetGripPoints(
    
13.         Entity entity, GripDataCollection grips,
    
14.         double curViewUnitSize, int gripSize,
    
15.         Vector3d curViewDir, GetGripPointsFlags bitFlags)
    
16.       {
    
17.         // It should not be anything else, since we are
    
18.         // filtering for block references
    
19.         BlockReference br = (BlockReference)entity;
    
20.         base.GetGripPoints(entity, grips,
    
21.           curViewUnitSize, gripSize,
    
22.           curViewDir, bitFlags);
    
23.         // We'll only remove it for dynamic blocks
    
24.         if (br.IsDynamicBlock)
    
25.         {
    
26.           GripData toRemove = null;
    
27.           foreach (GripData gd in grips)
    
28.           {
    
29.             if (gd.GripPoint == br.Position)
    
30.             {
    
31.               toRemove = gd;
    
32.               break;
    
33.             }
    
34.           }
    
35.           if (toRemove != null)
    
36.             grips.Remove(toRemove);
    
37.         }
    
38.       }
    
39.     }
    
40.     [CommandMethod("RemoveInsertionPoint")]
    
41.     public static void RemoveInsertionPoint()
    
42.     {
    
43.       Overrule.AddOverrule(
    
44.         RXClass.GetClass(typeof(BlockReference)),
    
45.         new MyGripOverrule(), true
    
46.       );
    
47.       Overrule.Overruling = true;
    
48.     }
    
49.   }
    
50. }
