As with a curve, you can lay points out on a line by specifying the number of points (in which they’re evenly spread along the line) or by specifying the spacing. Below is a line with 10 evenly-spaced points.
To lay out points on a line, proceed as follows:
Select Construction > Layout > Points on Lines.
Select one or more lines. The Layout Points on Lines dialog will appear.
n Spaced Points radio button: SA will create the specified number of points spaced evenly along each of the selected lines.
Spaced at Distance radio button: SA will create points on each line starting from the tail of the line, using the prescribed spacing.
Group field: The name for the resulting point group.
Choose the desired options, then click OK.
