Staggered was created for those instances when you need to dimension smaller distances within a larger dimension, as shown in Figure 6. You'll see that the dimensions are stacked on top of each other with their text staggered from left to right as you ascend the stack. You can use this option to create multiple baseline dimensions. The system variable dimdli still controls the distance from one dimension line to the next. I did notice that if the dimensions were too close together, they didn't automatically jog but rather landed on top of each other.
Diameter works similarly to radius dimensioning.
This option dimensions according to the various dimension-variable settings. After selecting a new reference or Datum point, AutoCAD returns to the previous point. Here you can easily add or remove points you want AutoCAD to take into consideration when dimensioning. Figure 7 shows you the points that show up when you select Edit mode. This allows you even more control over the final dimensioning outcome.
