Select the stand(s) you would like to move, you should see Red nodes appear on the corners of the stands as shown below.

If the corner nodes are Blue, press the Space bar on your keyboard to toggle them back to Red nodes.

Select a Red corner node, preferably one that is not next to another node to make it easier for you to select.

You are now in 'move' mode. While you are in this mode, press an arrow on your keyboard in the direction you would like to move the stand.

A box will now appear for you to type in the distance you want to move the stand and shows you the direction the stand will move. Type in the distance and press OK.

TIP: You can type any distance in this box if required. For example if you only needed to move your stand by 0.12m to move it away from a pillar or something, just type in 0.12.
