If the shape of the pond needs to change slightly, I can just stretch the grip of the path. Increasing or decreasing the number of symbols is easily done in the array properties of the contextual ribbon. The beautiful thing is that its not a static entity – I don’t have to start all over if something changes. I then froze that layer because I don’t need it to display, I just want it to define my path. That’s what I did for the pond in the picture below:Īfter drawing the top and toe of the pond, I offset the top to the midpoint of the slope, and did a path array of the slope symbol along that line. But what if you’re not using gradings, corridors or even Civil 3D for that matter? In AutoCAD 2012 you can use an associative array. Now, using Civil 3D, you can get those symbols automatically drawn for you if they are part of a grading object or corridor. Nice, but you still had to do it one by one. Back in the day, I used a lisp routine that automated the process somewhat, drawing the line and slope symbol for you by picking the top and toe points. Let’s take a look at how it can be used.Ī common, mundane task when creating grading plans is adding slope symbols to indicate the direction of the slope from top to toe. While that’s still a powerful option with unique advantages, similar functionality is now possible with the path option in associative arrays. Linetypes with text, direction arrows, fence linetypes, etc. Recently, I wrote about using Civil 3D alignments as complex linetypes. With the advent of the associative arrays in AutoCAD 2012 products, we’ve got a great new tool with some interesting possibilities.
