Points on the base size that are not grade points can be configured as grade points.
When adding a new point and defining it as a corner point, it will be defined as a grade point by default.
To configure a point as a grade point:
If it is not already open, open the Sizes and Grading pane.
In the 2D window, click the point on the base size that you want to configure.
Go to the Sizes and Grading pane, and click Grade Point:
The point is configured as a grade point.
You can also use the table to input values manually and configure grade points locations. First, select a point on the piece and ensure that Grade Point box is checked.
