To Move Dimensions
You can move dimensions within a view using the following procedure:
1. Select the dimension you want to move. The cursor changes to a four-pointed arrow.
2. Drag the dimension to the desired location.

You can use the CTRL key to select multiple dimensions. If you move one of the selected dimensions, they all move with it.
You can move created (driven) dimensions by editing the attachment point of the dimension. Select the dimension and click Annotate > Attachment. Select a new attachment point within the same view and middle click to place the dimension. Shown model dimensions can not be moved with this command, as it would require changing the reference within the model.   
You move dimensions according to their X and Y coordinates using Annotate > Move Special.
