Survey Figure Prefix Database

In this video, we're going to talk about survey figure prefix databases. I'll open the survey figure prefix database in our drawing, and we're going to discuss how and why the figures inside of our drawing are being displayed. So first, I'm going to go ahead and zoom in on a couple of figures that are in our drawing. I'm going to navigate over to our figure prefix database. I'm going to drop it down, and we have our essentials that we're going to look at inside of this file. If you needed to create a figure prefix database, you can right-click on Figure Prefix Database and select New. We're going to go ahead and edit this one and manage our figure prefix database. Before you do an import, you usually want to have your figure prefix database set up obviously, because when we did our import, we told Civil 3D to create our linework using the figure prefix database. So if you didn't have the figure prefix database setup yet, then you wouldn't be able to import that linework, and the Field-to-Finish wouldn't be completed when you did that import. So what we're going to go ahead and do is we're going to look at the couple of objects that we have here, which is a fence line, a building, and a shrub line. So if we look at fence and we look at the FMC figure prefix. You'll notice that you can have the code set for FMC set to not be a break line, not be a lot line, be displayed on the V-FENC layer, and then the style of how you want that figure to be displayed and what site you'd like that certificate to go to. You also have your building which is down below in the BLD. The BLD is a break line, and these all come up when we're talking about creating surfaces, is not a Lot Line, is displayed on the V building, is displayed as basic, and it goes to the Survey Site. Then you also have your shrubs which are ESHB, it is not a Breaking. So breaklines are defining hard edges on a surface. It is not a Lotline, it does not define a parcel, and it's displayed on a specific layer with a specific style on a specific site. If you needed to create a new code set or figure prefix database or a figure prefix, you would go ahead and click the plus sign to create a new one. If you wanted to copy one, you would select a figure prefix, click on the Copy, and then you would create a copy down below. If you wanted to delete some that you had already created that you didn't need anymore, you could click the Delete option. So I'm going to go ahead and click Cancel, because I don't want to change any of my figure prefix database information. The one thing to note is that if you hadn't created your figure prefix database before you did your import, you don't have to go back and delete your import and then redo it with your new figure prefix database. What you can do after you've done your survey import, is you can go to your Survey Points and you can right-click on it, and you can choose Process Linework. Inside a Process Linework, you can choose your figure prefix database, and you can tell Civil 3D to either process the linework and insert your figures, or you can tell it to just process alignment and do no insertions. If you chose to say no to the insertion of the figures, then if you wanted to then later import those figures into the drawing, you'd go to your figures inside of your survey database, and you can right-click and choose to insert your fingers into drawings. So just because you've done a import does not mean that you're locked in on all of your survey information. There is plenty of edits that can take place inside of your survey database after the import takes place. So inside of figures if you right-click, you'll notice that you can edit figures, you can update your figures based on changes that you've made in the datasets. You can create new breaklines, you can create figures interactively, you can create figures from objects. So you can draw in a polyline and then create a figure from that polyline. You can modify existing figures that are in your drawing. Same thing with the survey points, just because you've imported the points, say one of the points had the wrong elevation, you can go ahead and go to your points. You can update them or you can go to points, you need to go to Edit points, and you can look at all the points that you've imported and change their Eastings, their Northings, and their elevations, and their descriptions. So if a description was wrong, say the code set was incorrect, there was a typo, or you missed your figure prefix, say you said EG instead of EP, you could go in and you could correct this by clicking on it and erasing the the G if there was G here, and you can change it to P. That would then allow you to reprocess your linework using the correct code set, and then it would update your figures, and you would have your edits done in Civil 3D rather than having to fix your datasets and then re-import them.
