Before starting this procedure, identify a curve to use for the path. It can be one that you import or create with one of the curve tools. See Draw NURBS curves. You can select a curve tool to create a smooth or jagged curve, depending on the type of animated movement required.
If you draw a curve and want to join the two ends, creating a closed loop, select the curve, then switch to the Modeling menu and select .
Before attaching the object to the path, it is recommended that you ensure correct orientation of the when it travels down the motion path. You should be able to identify one of the X, Y, or Z axes on the object as the forward direction, and another as the upward direction. If this is not the case, or if you want to verify the object orientation, use the following procedure:
To adjust object axis orientation
This lets you select the Local rotation axes for the object.
If you are going to attach the object to the curve now, do the next step to switch to object selection mode.
To create a motion path by attaching an object to a curve
When Follow is on, the Front Axis and Up Axis options determine which of the three local rotation axes sets the front and up of the object respectively.
Two motion path position markers with numbers appear at each end of the curve. These markers indicate the start and end frames of the animation path.
