It seems like every time I talk to a relatively new user of Civil 3D, they tell me that there is so much in the software that they don’t use simply because they know a core group of functions and don’t really have time to dig into other areas. We all know that Civil 3D does indeed contain a variety of functions and routines. Let’s take a look at some of the tools that you may or may not be familiar with. Quick Profile & Quick Cross Section You may be thinking that this part of the article is about two tools and not one tool with a large name, right? Maybe the title for this article should have been, “4 Tools in Civil 3D That Rock”? Well, it could have been, but I decided to write about these two tools together because of the similarity in what they give us. However, make no mistake about it; these are two separate tools. When you first select this tool, you are prompted to Select object or by Points. What this means is that before you start the command, you can draw a polyline in the location where you want the command to read profile data, or, you can click points on the screen. My preference is to draw a polyline first because if I move that polyline, the profile view will dynamically adjust based on where I move the polyline. After selecting the polyline or picking points, you are then prompted to select the surface or surfaces that you want to show in the Quick Profile and the Profile View Style as shown in Figure 2. One important thing that I like to point out in this dialog box: you’ll notice that I changed the profile style for the FG Road surface. I always make sure that I used different styles when profiling more than one surface. At this point I can simply click OK and then place my profile view in the drawing as shown in Figure 3. It works great! One thing to remember about this tool, however, is that it is intended to be purely an inquiry tool so, when you save the drawing, this Quick Profile view will go away. Well, that reminds me of a tip regarding this fact. If you want to maintain a profile view instead of having a temporary one, simply turn the polyline into an alignment, then create a profile and view from that. This is another reason why I like using the polyline option instead of clicking points. To use this tool, simply right-click on it, and click Execute. From there, you are prompted to select a surface. After selecting the surface, you are then prompted select 3 point or multiple points. The difference between these options are that a 3 point gives you the cutting plane and the view directions, hence, the 3 points. This will produce a single section view. The multiple option will allow you to click many points along the surface. When you use this option, you will also be prompted to select sample interval as well as left and right swath widths. This process kind of simulates alignment and sample line creation, but as noted before, everything is temporary because it is an inquiry tool. First, let’s try the 3 point option. Click on 3p on the command line, then click the points you want to use as the cutting plane for the view, then click the 3 rd point as the direction you want to view from. Figure 5 shows an example of this. At this point, a dialog box will appear with selections for section and section view styles as well as band style set. For some reason, I have only been successful when selecting Standard as my section and section view styles. For me, when I have tried using other styles, all I got for output was two rectangles with no data. For this reason, you may want to go into the Standard styles for section and section view and modify them to look the way you want. You will then be prompted to select the section view origin, meaning where you want to place the section view. So, pick an empty spot and place it.
