Editing Feature Lines

00:00

RUSS NICLOY: Hello and welcome to Feature Lines

00:02

in Project Explorer.

00:03

My name is Russ Nicloy, Civil Solutions Specialist

00:06

at MACER Technologies.

00:07

In this course, we are looking at Project Explorer for Civil

00:13

you to work with and analyze objects in your design file.

00:16

This session is part 2 of

00:20

Currently we are looking at how to create and edit feature

00:22

lines through Project Explore.

00:24

In this learning path we are at the Edit Feature Lines course.

00:28

This session we'll look at identifying the correct feature

00:31

line and vertex for edits.

00:33

How to manipulate the elevations and slope of feature lines

00:36

segments, and how to compare a feature

00:38

line to alignment or surface objects

00:40

all through Project Explorer.

00:43

So, we have our feature lines in this file,

00:47

we can see them right here.

00:49

And in the list, it's not that they blend in with the others

00:52

but there are so many others it'd be easy to get this wrong.

00:55

One of the things that you can do

00:56

to identify which feature line you're working with,

01:00

is to come up and filter by.

01:02

I'm going to click the dropdown there

01:04

and you can filter by which site.

01:06

I'm going to filter by the ditch grading site,

01:10

and now all the other feature lines are gone,

01:12

only the ones that are on that site, on the ditch grading site

01:16

are available.

01:17

Now, I still need to identify which feature

01:20

line we're working with here.

01:22

So, when I select one, I'm going to hit the Control key

01:25

and it will highlight.

01:30

Taking that one step further, with the north ditch line

01:34

highlighted.

01:35

The three points down below here are the vertices

01:38

of that feature line and you can see them

01:40

highlighting on the grid above.

01:45

With one selected, I'll hit Control

01:47

and it will highlight in a way that's pretty

01:50

easy to see on the screen.

01:56

Now, something else that we can do

01:58

to help us understand what we're editing

02:00

is to compare this feature line to something

02:04

in the neighborhood, like an alignment profile or surface.

02:07

I'm going to go up to the compare to option

02:09

here, click that dropdown, I'm going

02:12

to find West Mineral Avenue, that's

02:14

the alignment that we're near.

02:15

Now, click on the alignment, there

02:17

is a profile here as well, but I'm

02:18

going to click on the alignment.

02:20

And then when I select on one of these vertex points

02:23

and hit Control, it now gives us the distance to that alignment.

02:29

And we can do the entire feature line all at the same time

02:32

if we would need to.

02:37

Now, you'll notice if we can edit the purple text in here,

02:41

really the only purple text we can edit is the elevation.

02:44

We can't edit the grade ahead or back,

02:47

but we can set the elevation.

02:50

What we can do is right click on the feature line name itself,

02:54

come down set a constant grade holding the start point.

02:58

I'll left click on that, and in here we can set this

03:01

to a particular grade or slope.

03:04

I'm going to put in a negative two for the grade,

03:08

you could do the slope here.

03:10

I'll click OK, and now it drops that down

03:13

at that particular grade.

03:16

Now, that's great for the first segment,

03:18

but we still want it to tie-in to the surface

03:20

on the other side.

03:21

So, what I'm going to do is change my compare to,

03:24

I'll scroll all the way down to the bottom where

03:28

the surfaces are.

03:28

I'll pick the existing ground, and now we

03:31

can see where that is.

03:33

Not only can we see it but also if I

03:36

scroll over the compare to fields over here will tell us

03:40

what the surface is doing at that third point.

03:48

Double click on the elevation 80.142 and that

03:55

now ties back into the existing ground.

03:57

We have a -2% down to this point and then add a little under -1%

04:03

to the tie-in on the other side.
