Note: Depending on the number of factors and the specified value for Number of Runs, you may want to increase the average number of initial points per design point by selecting Advanced Options > Set Average Cluster Size.
The design region can be defined using the Disallowed Combinations option from the Space Filling Design red triangle menu or by selecting Add linear constraints under Fast Flexible Filling in the list of Space Filling Design Methods. However, the design is generated differently for these two methods.
Note: Depending on the nature of the constraints and the specified Number of Runs, the default coverage of the unconstrained design space by the initial uniformlygenerated points may not be sufficient to produce the required Number of Runs. In this case, you may obtain a JMP Alert indicating that the algorithm “Could not find sufficient number of points.” To increase the initial number of points that form the basis for the clustering algorithm, specify a larger average number of initial points per design point by selecting Advanced Options > Set Average Cluster Size. (See Set Average Cluster Size).
When linear constraints are specified using the Add linear constraints option, the random points that form the basis for the clustering algorithm are uniformlydistributed within the constrained design region. The clustering algorithm uses these points.

Remove the Smoother by clicking the smoother icon (the second icon from the left in the row of icons directly above the graph).

5.

In the Graph Builder red triangle menu, click Show Control Panel to deselect it.

You should see a graph similar to the one in Fast Flexible Filling Design with One Linear Constraint. Note that the points satisfy the linear constraint . Also, consider the distance between any point in the design space and its closest design point. Note that there is not much variation in these distances.
