You can sprue units to each other to fit more units into your puck. Make sure that the units have enough support from the puck. You want to be cautious as to where you place them for future nesting jobs.
- Move the units (using the move button) you want to sprue together as close as you can without having the offset lines touch the other unit or any sprues.
- Zoom into the areas you want to sprue. When you click on this point, the sprue will connect to the closest part of the neighboring unit.
- That's all you need to do to sprue the units together. Again, you need to be aware of how much zirconia is being taken away. There needs to be an island of zirconia going through the puck for the units to hang onto.
