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:
From the menu, select Construct>New Points>Layout>Points On Lines.
Select one or more lines. The Layout Points on Lines dialog will appear.
n Spaced Points. SA will create the specified number of points spaced evenly along each of the selected lines.
Spaced at Distance. SA will create points on each line starting from the tail of the line, using the prescribed spacing.
Group. The name for the resulting point group.
Choose the desired options, then click OK.
