This window lets you create a transition at any surface of the block you are zoning.
- Transitions along
Specify at which of the six surfaces of the block you want your transition to be created, by selecting and I, J or K-plane and whether it is the corresponding lower or upper surface of the block.
- Transition orientation
The orientation of the transition.
- Transition Types
The image above shows you the two transition types you can use, namely a 4-2 transition and a 3-1 transition. To use a particular type, the index range in the direction of the transition orientation must be a multiple of 4 or 3 respectively.
A message will tell if a valid transition type exists for the boundary you have defined. If more than one type is valid, you will be asked to choose the transition type you want to use.
