Chapter 07 – AutoCAD Civil 3D 2013 Essentials – The Essentials and Beyond

hello my name is Eric Chappell author of
autocad civil3d 2013 essentials and this
is the additional exercise for Chapter
seven in this exercise we're simply
continuing what we already did earlier
in the chapter but this time for the
Madison Lane and Logan Court alignments
so the first thing we need to do is
create a surface profile using the eg
surface so I'll go to my home tab launch
the profile create surface profile
command I'm gonna do Madison Lane first
and add eg as my profile now normally I
would go straight in to draw in profile
view but to complete the steps in the
order that they're laid out I'm going to
go ahead and just click OK here panorama
pops up and lets me know that I've
created a profile and then I'm just
going to repeat the command for Logan
Court so I've created the profile but I
haven't shown it yet in the drawing
that's step two step two is to create a
profile view using the default profile
view style and band settings so I'll go
to my profile view portion of the home
tab of the ribbon create profile view
I'll select Madison Lane first using all
the defaults here create my profile view
right there and then I'll repeat the
command for Logan Court again using the
defaults
the next task that were asked to do is
to create a layout profile that roughly
matches the existing ground profile so
I'll zoom in to my Madison Lane profile
view and then I'll go to the Home tab of
the ribbon and do profile profile
creation tools and that's going to bring
up the tool bar once I click the profile
view grid and I'm just going to go ahead
and accept the defaults here that brings
up my profile layout tools toolbar I'm
going to say draw tangents with curves
and I'm going to snap right to the
beginning of the profile and if you
remember the instructions say to try to
follow existing ground as closely as
possible so that's what I'm gonna do
pretty simple profile there just three
or four PV eyes and then the same thing
for Logan Court and Logan Court is so
simple I'm just gonna go ahead and do a
straight line for Logan Court even
though I picked tangents with curves
because I'm only picking two points it's
just going to give me a straight line
now I don't have to snap to the
beginning and ending of the surface
profile it's just a good assumption to
make that you're tying in at one end or
the other but if you need to be in a
specific location then by all means you
know you can tie in above or below
existing ground but that satisfies the
next requirement which is again to
create a layout profile that roughly
matches the existing ground profile the
next task that we're asked to do is to
round off the station and elevation
values for each PVI
since we're in the imperial data set
this is going to be to the nearest five
feet four stations and the nearest point
five feet for elevations so what I'll do
is click on the Madison Laine profile
first and now let me back up a few steps
I'm gonna click on Madison Lane I'm
going to click geometry editor and then
grid view that brings up my alignment
data in panorama and now I can see my
first station is very close to three
plus fifty so
sounds good 3 plus 15 now I want to
round to the nearest 5 feet so this
one's going to be 6 plus 80 and by the
way you can just type in 680 and that
works fine and this one looks like it's
going to be 965 now for the elevations
we want to be to the nearest half a foot
so I'm going to go ahead and do the
beginning one even and do that at 193
this one will be 190 this one will be
173 and this one's gonna be 180 point 5
now of course your numbers are going to
be different because we're our first
attempt at drawing the profile it was
kind of freehand by design so your
numbers may come out slightly different
you may even have more or less PBIS than
I have and now we'll go to Logan Court
do the same thing so again I'll click
geometry editor profile grid view this
one's pretty easy because it's already
rounded off for the stations for the
elevations this is going to become 174
and this is going to become 175 all
right so that satisfies the requirement
of having rounded values for stations
and elevations the final task is to make
sure that the profile meets the criteria
of the subdivision design check set so
how do we do that
well we'll start by going to profile
properties we'll go to the design
criteria tab and say that we want to use
criteria based design we don't want to
use a criteria file we do want to use a
design check set called subdivision it's
that simple we click OK we check to see
if there are any violations and we do
have one here which is probably going to
be a slope violation so I'm going to
turn on my tooltips
I'm going to turn on my rollover tips
so that when I hover over this marker I
actually do get some information
tangent grade must be between a half
percent and five percent I'm going to
say that's a little too steep so let's
take this PV I and move it up a little
bit turn off my o stop so I can kind of
run freehand here so that took the the
warning away we're going to do the same
thing for Logan court profile properties
design criteria using the subdivision
design check set and it looks like we're
a little too flat on this one so I'd say
we're not steeper than five percent we
must be less than half a percent so I'm
going to click this in drag it down a
bit of course I can get more refined
with my design I can even go into
geometry editor and say okay well let me
make this exactly half a percent of
course that makes my elevations not so
round but actually it does in this case
170 3.5 to 175 gives me half percent and
I guess because it's just on the line
it's still a little bit unhappy so let's
make this 0.5 1 and that makes the
shield go away so you get the idea of
how we can make our design comply with
the design check set so that takes care
of the additional exercise for chapter 7
