I'm not aware of a defualt functionality for adding arrows to a line at set intervals. However using the sketch tools and layers (if you choose...just makes the colors, line weights etc. more automatic) you can add sketch lines and insert blocks (of the arrow heads) and create this look. See the help file for creating blocks. They can be shaded as well.
For example you could have a water layer and an air layer. Set the line weight and style in the layer settings. You would have to either change to dashed formats on an individual line basis or set multiple layers for air and water etc.
Workflow would be: select layer, sketch lines, add arrows (blocks).
Hope this helps.
Thanks! I'll try that.
Welcome to the forum.
On top of what Jason said, you can sketch splines and change the style
as well as the line thickness in the line format toolbar. Then create an arrow
like you showed in your pic and save that as a block to insert whereever and how
ever many you need. Hope this helps.
