Displaying Index Numbers of Multiple Points

This is the points used this time.

Components used: (1) Point (2) Point List

This is the basics of the Point List.

Point List(P) connects data in which multiple points are set.

In this case, multiple points are set in the Point.

Point List(S) is used to input the size of the number to be displayed as a numerical value.

As you can see, the numbers are now displayed at the point positions.

This shows the Index number of the points.

Let’s change the size of the numbers.

Change the number on Point List(S) from 40 to 100.

The size of the number is now larger, as shown here.

In this way, the size of the number can be increased or decreased.

Let’s look at an example of using Point List.

Point Lists are often used to check if the order of the points is correct.

In this example, we will create points to divide a curve and check if the order of the points is correct.

Components used: (1) Curve (2) Divide Curve (3) Point List

Divide the curve set in Curve by Divide Curve and look at the index numbers of the points in the Point List.

As you can see, the order of the points in which the curve is divided can be confirmed.
