&lt;td&gt;&lt;/td&gt;
&lt;td&gt;&lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;h1&gt;&amp;nbsp;&lt;/h1&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;h1&gt;Question:&lt;/h1&gt;
&lt;p&gt;In MX Road, there is this option in surface analysis for viewing the flow based on the ground surface called flow arrow and I can see that in InRoads there is this option called slope vector. Is slope vector actually similar to flow arrow? How do I get the flow arrow analysis inside InRoads?&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;h1&gt;Solution:&amp;nbsp;&lt;/h1&gt;
&lt;p&gt;Here are two options to view the flow of your surface with flow arrows.&lt;/p&gt;
&lt;p&gt;Evaluation&amp;gt;Hydrology and Hydraulics&amp;gt;Trickle (Hydrology and Hydraulics is an Application Add-In, Tools&amp;gt;Application Add-Ins&amp;gt; Hydrology and Hydraulics, this command will be placed on the InRoads dialog box at Evaluation).&lt;/p&gt;
&lt;p&gt;The Trickle command dynamically traces the path of a drop of water down a selected DTM surface or up the surface to the water source. You can also display the path or paths at a selected XY location. The path lines are always&lt;br /&gt;drawn from high to low so that you can use your own linestyle to indicate the direction of slope.&lt;/p&gt;
&lt;p&gt;Or&lt;/p&gt;
&lt;p&gt;Surface&amp;gt;View Surface&amp;gt;Annotate Feature (Slope Direction)&lt;/p&gt;
&lt;p&gt;This command annotates the slope direction of a feature in plan view. You can define a cell to use as the arrow, the offset, and the option to annotate at every segment or at a specified interval.&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;
