By default, control points are 4’-6” above the floor level of the current building location. You can edit the elevation of a control point on an animation path using the Elevate Control Point tool. This adjusts the path so it goes up or down depending on the elevation you specify. For example, if your path is on the ground floor and you have a control point at either end of a staircase, elevating the top control point will make it seem as if you’re walking up the stairs.
To edit the elevation of a control point:
Select Tools
> Animation > Elevate Control Point, or click the Elevate
Control Point button on the Animation toolbar.
Click on the control point you want to edit.
In the Elevate dialog, the value currently shown is the current elevation of the control point. Edit the elevation as desired.
Click OK.
