In the main workflow wizard tool bar click on the "Select or Create Stock/Blank" button.
In this window you can select your partially used disks, or create a new one by clicking "Create".
Look at the label of your disk, or the box, for the information required. If you are using CAP disks, the information will be on the label.
This CAP FZ disk has all the information on the front, and this information will be input into this Sum3D screen.
Shapes - This should stay at the Round diam. 98 unless using a different disk type.
Thickness - Will be right on the top of the disk. This disk says 14mm so I put in 14.
Shrinkage Factor (Some versions of Sum3D may say Reduction Coefficient) - This will be right on the top of the disk also. Some disks have this on the side.
Stock/Blank Name - This can be whatever you want to name this disk. It is important to put a name, or the disk will not save. The name that is decided should be written on the side of the disk so it is easy to find in your used stock later on.
Lot Code (Not all versions of Sum3D have this) - This is also on the disk next to "LO".
