When you create a dimension, a preview is provided after you specify enough references to create the dimension. You can drag the dimension preview to choose the placement location. From the Dimension tab you can edit the properties of the dimension. When you select a dimension, the Dimension tab opens automatically. When the dimension is no longer selected, the Dimension tab closes automatically. After creating a dimension, you can immediately edit the dimension and then continue selecting references to create the next dimension. This allows you to create multiple dimensions and edit the properties of each one without interrupting the creation workflow.
