That's what I thought, but it's not working right. I see the two icons on the toolbar but they both have little red x's on them. When I press them nothing happens, I can't switch from grid to object. I'll try reinstalling - I used the DLL dated 1/22 with the Addins folder earlier in the thread.
If you have the two icons then it should be working.
The one with a grid and red dot toggles grid snap on/off
The one with a cicle and red dot toggles object snap on/off
When they are active the border around the icon should go dark, so click on them until both are dark, zoom in a bit then select 'Draw a Polyline' , move the mouse, you should see the cursor jump from one grid point to the other. Press the icon again and the mouse will not jump to grid positions.
