Slope Arrows

[jedwhitney]

I have too many arrows shown on the created surface. How do I limit the amount of slope arrows shown?

You will get slope arrows everywhere you have a triangle. You can change the size of them but if you want less you have to simplify your surface.

You could make a Grid Volume and use that surface for the slope arrow analysis.  The specified grid spacing will make a uniform grid array of slope arrows.

To make the grid volume surface you'll a Base Surface at elevation 0.  Just make a large rectangle around your current surface at elevation 0 and use it as a contour in for a new surface.  Use this new surface as the base surface for the grid volume surface and your current surface as the comparison surface.  Use a surface style that shows the slope arrows.

hI @jedwhitney  when you turn on Slope Arrows in your surface style, in the default you will see many slope arrow might be like this 

then if you go to surface properties, in Analysis tap, selected Analasis type to Slope Arrows, then you will see some thing like this  

but if would like to see only one slope range, for this sample, slope arrow between 50-100%, then you will see slope arrow like this
