In this video, we're going to look at linework code sets.
00:10
We're going to open a linework code set and discuss the parameters inside of that code set.
00:13
And then we're going to compare those codes to a survey dataset to see how the codes are read inside of that survey dataset.
00:20
So when we set our survey user settings,
00:23
we directed Civil 3D to look to a specific file that contained our equipment databases, our figure previous databases, and our linework code sets.
00:31
So if that was setup correctly,
00:33
what Civil 3D is going to do now is it's going to populate a already created linework code set for you called Essentials.
00:41
If you were working inside of Civil 3D not as part of these video sets, what you would have to do inside of Civil 3D, first, would be,
00:48
to set up a linework code set unless less where you're working has linework code sets specified and has a location for you to direct Civil 3D to.
00:58
So if you need to create a new linework code set, what you're going to go ahead and do is right click on Linework Code Sets select New.
01:04
Since we already have a linework code set, we're going to go ahead and go to Essentials and we're going to right click, select Edit.
01:10
So inside of this window is the Edit Linework Code Sets window,
01:15
and we are basically setting our codes for how Civil 3D is going to look at the field data inside of a survey database.
01:23
So we're going to go and look down the list, starting with coding methods.
01:28
What this is basically saying is that after your point identifier, how is Civil 3D going to tell when your field codes start.
01:38
And so you have a point description of, say, GS for ground shot,
01:42
and then if there's a Space, Civil 3D is going to see that space and it's going to say, this is the beginning of the field codes.
01:49
And so the field code escape is kind of the opposite of that, it's saying, once I've started reading these field codes,
01:56
when do I decide that I'm done reading that field code, and I switch over to comments.
02:01
And so a slash would say, I'm going to stop reading those field codes, I'll continue to the end of the line,
02:05
but I won't implement any more text inside of this field code.
02:10
Start in comments mode is basically flipping how Civil 3D reads everything.
02:15
When you get to your field codes, it will start in comment mode and it will wait until it sees that field code escape.
02:21
And once it sees that field code escape, it will switch over to reading the field codes and implementing them into the drawing.
02:27
An automatic begin on figure prefix match basically looks to your figure prefix database and says,
02:33
do I have a code that matches this figure prefix database?
02:38
If it does, I'm going to start to figure on it.
02:41
Otherwise, it won't start to figure and it'll look to the rest of your code sets.
02:45
If you don't have this checked basically, what you have to do is you have to always when you want to create a figure,
02:51
use your begin command for that figure.
02:55
So moving on, now we have our special codes for how to dictate what's going to happen with these figures.
03:00
So we have begin which begins a figure, continue would continue a figure,
03:04
and within that figure, close basically takes the point that you're on and loops back to the beginning.
03:10
Horizontal offset and vertical offsets are creating offsets, whether it's horizontal and vertical, and then stop as offsets stops those offsets.
03:18
Then we have our line segment codes.
03:21
We can recall to a specific point, connect to a specific point, create a rectangle on the point that we're reading currently,
03:28
make a right turn based on where we are at currently and an extension to there.
03:34
If you use a negative number, it would be a left turn.
03:36
And then you can also choose to extend a line past a point by using the Extend command.
03:42
Then we have a curve settings, which are begin curve, end curve, creating a circle on the point that we're at,
03:49
and then specifying whether a point is on a curve versus a beginning or an end of a curve.
03:55
The most common ones that I see used in my day-to-day work is begin and end curve.
04:01
And then also begin code, end code, and close.
04:07
So what we're going to go ahead and do is I'm going to open up a survey dataset, and we can see how these code sets are implemented.
04:13
So if we look at this code set or our survey data, you'll see point 306 is a building noted by the BLD,
04:22
and it begins it and draws that building from 306 all the way until you get to 309,
04:28
and then it finds the CLS command for close and it loops back and will create a closed shape from 306 to 309.
04:36
Then we move on to 310 and you will see that it begins a SWL, which is swale, and it creates a swale from 310 all the way to 333 and then ends it.
04:48
So we will not loop back to 310, we will just stop at 333 and start a new code at 334 and begin a new swale moving on until it reaches 341.
04:59
If we navigate all the way up to the top of our survey dataset, what you'll see is we're now working with an edge of pavement,
05:05
and you'll see begin of that edge of pavement moving on to the beginning of a curve of that edge of pavement,
05:11
moving on until we get to the end of that segment and the end of that curve.
05:15
So what Civil 3D does is it starts with a begin, it continues reading until it finds that end,
05:21
and if it encounters another code in between, it starts that code.
05:25
So we will have a linear segment beginning and then we will have a beginning of a curve,
05:30
and then we would have an end of the entire segment code and move on to a new code for figure.
