- I followed the example in the 4.0 Layout reference.
-
- Basically you make a simple object in modeler with the center
- point at it's base.
-
- Add a copy and clone it so there are several (the book has 4 total).
- Then move them into position of an 'arm'. Take the last one and parent
- it to the one before. Then take that one and parent that etc..etc...
-
- Now add a NULL object...name it to something like NullGoal
- Now, take the final child in the arm and set is goal to be
- Null goal.
-
- What you will find is it kind of works, but since the base
- of the child object is trying to reach the goal the last child doesn't
- look right. ie: it's base is reach not it's tip. So add one more null
- object at the end of the last child. Parent that to the child and
- also remove the childs goal. Then set the goal of this null object
- to be NullGoal.
-
- Now select the goal object and move it around and it should
- work fine.
