In AutoCAD 2011, the default action when double-clicking on a hatch object is to invoke the Properties palette for that object. In previous releases, it would invoke the Hatch Edit dialog box. In my AutoCAD 2011 – Putting things back to “normal” post, I briefly described how to restore the old double-click action. I have since seen some incorrect advice being given out about how to do this, so this post describes the correct process in full detail.

What to do

1. Invoke the CUI command.
2. In the top left pane, find the [+] next to Double Click Actions and left-click on it.
   
3. Scroll down that top left pane a little until you can see Hatch.
   
4. In the bottom left pane (Command list), click on any command and type H. This should take you down to the Hatch Edit command. If not, just scroll down a little more until you can see it.
   
5. Left-click on the Hatch Edit command in the bottom left pane, hold down the mouse button and drag the command up onto the top right pane until it hovers over the Hatch item you exposed in step 3. When the little blue triangle is pointing to Hatch, let go of the mouse button, thereby dropping the Hatch Edit command onto Hatch.
   
   Hint: you may find that the top left pane scrolls crazily while you attempt this step. Unfortunately, this is a “feature” of the CUI interface. If this happens, keep your mouse button held down and move your cursor up and down in the left pane until the scrolling comes under control and you are hovering over the right spot. You can avoid this if instead of dragging the command directly upwards, you move in a curcuitous route to the left or right, moving on to the top left pane from the side rather than the bottom.
6. Pick OK and that should be it. Double-click on a hatch object and see what happens.

What not to do

You may see some advice telling you to find the Hatch double-click action (step 3 above) and then edit the macro of the Properties command found therein from “^C^C_properties” to “^C^C_hatchedit”. Do not do this.

Why not to do it

If you edit the macro then try it out, it works fine. Why, then, does it matter which method you use? Because if you edit the macro, you are changing the action that occurs not just for the Hatch double-click, but for every place the Properties command is used. This means it will have undesirable side-effects in many places. For example, double-click on a circle after changing the macro and you will see something like this:
Command: _hatchedit
Selected object must be a hatch object or associative hatch block.
HATCHEDIT does not support old-format non-associative hatch blocks.
Select hatch object:

What to do if you’ve already done it

If you have already changed the Properties macro, go back into CUI and reverse the process, changing the macro back to “^C^C_properties” (without the quotes). When you are happy that you’ve fixed that up, use the click-and-drag method described above.
