Use a Cut Point 1D (), Cut Point 2D (), or Cut Point 3D () dataset to plot and evaluate a value in a certain point along time or along a parametric solution and to create cross-sectional point plots. The choice of 1D, 2D, or 3D only controls the type of input the dataset accepts. For example, a Cut Point 1D can only be added to 1D datasets, Cut Point 2D can only be added to 2D datasets, and so forth. Any of these can be used to make a point graph plot along time and so forth.

Add a Cut Point 1D dataset for one point as cross-section data. Add a Cut Point 2D or Cut Point 3D dataset to, for example, plot the value in a certain point along time or along a parametric solution and use the dataset in its original dimension. Useful ways to visualize and display data in cut points are through Point Evaluation nodes () under Derived Values and Point Graph nodes () under 1D Plot Group nodes.

To specify the point data coordinates using the Entry method list:

Select the Snap to closest boundary check box to snap the selected points to the closest boundary in the geometry. Use this option when evaluating a variable that is available on boundaries but not in domains. Otherwise, leave the snapping off (the default setting) to avoid the additional computational cost.

By default, the Cut Point datasets create a point number variable so that you can refer to that variable in a Point Graph, for example, where you want to plot some quantity at those cut points. The default variable name is typically cpt1n, for the first Cut Point dataset. Enter another variable name in the Point number variable field if desired.
