I have an object that is far away from the starting point grid. When I Add a Bezier Curve, it is on the grid and switch to Top view, it is too far away to see and manipulate. How do I get my object in the center of the grid so I can do the curve-the-object around the Curve trick?
Sometimes it is difficult to locate the exact location of your object in the 3D editor.
You can directly set a number of properties for Meshes and other items in the Properties Panel.
The Properties Panel can be toggled with the 'n' key in any 3D view(and a number of other views).
To set the Location to 0 for X,Y,Z click and drag from the X input box to the Z so they are all highlighted. Then just type 0 to set them all to the same value.
There is the simple way to do that without changing your object location.
Add an Empty object then make it follow the curve. After that, add a Copy Transform constrain to your object with target is the Empty object that you just created.
