Summary:

You will regularly need to position objects a certain distance away from other objects. Whether it's a door needing to be a certain distance from a window, or two Piers needing to be a certain distance apart, positioning objects is a crucial step. In ArcSite, green measurement indicators show you the relative distance between objects.

You can move any selected object and then define a relative distance to other objects nearby.

In the image below, the middle line was moved and now displays three measurements (Green). Tap on one of the measurements to specify a specific distance to create between the two objects.
