Understanding Drawing Scales and Data References in Civil 3D

Enhancing Drawing Completeness with Data References and Scales in Civil 3D

Learn how to create a sheet in Civil 3D by importing more data references and adjusting the drawing scale. Understanding how labels update based on the drawing scale and how to preserve the drawing, create data shortcuts and references will prove vital.

Key Insights

  • The generic notes created in Civil 3D are objects that will annotate and update based on the drawing scale. Changing the drawing scale affects the lot labels, street labels, among others.
  • Creating data shortcuts and references is an important step in bringing more data into your drawing. This is exemplified by adding in alignment for the highway and selecting corridors.
  • Saving and preserving the drawing is crucial to prevent loss of work and preserving the original state of the drawing before further modifications are made.

Note: These materials offer prospective students a preview of how our classes are structured. Students enrolled in this course will receive access to the full set of materials, including video lectures, project-based assignments, and instructor feedback.

So before we go ahead and create a sheet, we're first going to bring in a couple more data references to make our drawing look a little bit more complete. And we're going to go ahead and talk about drawing scales.

So inside of the drawing, the important thing that I noted about the generic notes that we created was that they are civil 3D objects and they will annotate or update based on our drawing scale. So I'm going to show that now by changing my drawing scale from this one in 20 up to one in 60. When I changed to one in 60, you're going to notice that all of my labels updated, but more importantly, you're going to see that my lot labels updated.

And so did my street labels here. So these labels, these generic note labels can be used for multiple different purposes inside of civil 3D, and they will update and change based on the scale that your drawing is set to. So I'm going to go ahead and bounce back to one in 20.

And then we're going to go ahead and open another drawing to create some more data references. So before we do that, though, I want to go ahead and save this drawing off. I want to preserve what we have now as our pipe drawing, and I want to save this off as a finished drawing.

So I'm going to go ahead and do a save as I'm going to go ahead and go in here and erase out pipe and type in fin and then save. Now we are working in our sieve 203 fin dot DWG. I'm going to go ahead and go to start.

I'm going to click open and I'm going to open up our sieve 203 data file. I'm going to go ahead and click open on that. And then I'm going to navigate over to the tool space.

I want to bring in my corridors because I want to turn off some information, but I want to leave on my back of sidewalk. I want to leave on my curb lines so that we have a little bit more of a complete drawing. So what I'm going to go ahead and do is I'm going to go to my data shortcuts.

I'm going to right click. I'm going to click create data shortcuts. And then from here, you can see these are grayed out because they're already created data shortcuts.

So I'm going to go ahead and go down here. I'm going to go ahead and add in my alignment for my highway. So I'm going to go to my alignments.

I'm going to go to my center line alignments. I'm going to go to EX highway. I'm going to go ahead and click OK.

Well, I'm not going to click OK yet because I want to go down to my corridors. So I'm going to go down here. I'm going to select all of my corridors and I'm going to click OK.

Now that I've clicked OK, you can see here that all my corridors are in here as data references. So I'm going to go ahead and close up my data file. I will click yes for save.

And now that I'm in my CIV 203 FIN, I'm going to go ahead and bring in some new data shortcuts. I'm going to go ahead and go to my corridors. I'm going to right click on Dev Branch and I am going to create reference.

My corridor reference is being told to have a name of Dev Branch, a description, a corridor style of basic, and then my baselines. So Civil 3D is giving me a warning of when you create a reference to a corridor, references are automatically created to its baselines. So I'm going to say OK.

So I'm now bringing in the information for this. I've now gone and I'm going to check Dev Branch and create reference. I'm going to go ahead and click OK.

I'm going to go ahead and go to Dev Main, create reference, and click OK. I'm going to go ahead and go to Dev Main Branch, create reference, and click OK. I'm going to go ahead and go to Dev Main End, create reference, click OK.

I'm going to go to my existing highway, create reference, click OK. I'm going to go to my highway Dev Main Intersection, create reference, click OK. And so from here, what we can see is that we have information based on our edges of the roadway.

Some of our sidewalks are showing up. When I select these, you can see I have a flow line, a back of sidewalk. This is starting to look a little bit more complete for us.

So I'm going to go ahead and escape. I'm going to go up to my alignments. I'm going to go to my centerline alignments.

I am going to go to my EX highway. I'm going to right click and I'm going to click create reference. Actually, it's already grayed out because it brought in my EX highway alignment with that corridor that I brought in for my EX highway.

We're OK there. I'm going to go ahead and minimize these down and then I'm going to zoom out. I'm going to save my drawing and then I'll meet you in the next video.
