Closed Caption:

exercise 12 and this exercise we take a
look at the functionality in creo
parametric to point out when importing
DWG files in this case we're going to
build this little wheel that you see
here from an imported DWG so let's begin
first go to file open down below here
under files make sure you scroll down to
about the middle you'll find DWG and
find the exercise 12 DWG which you can
download it for ten to one . com veerta
and UX of the number one open it up when
it prompts you to open it you want to
open it into a part while and then use
the templates if you don't use a
template it doesn't bring in the plains
the datum plane so you have to Adam not
a huge deal but it does take sometimes
you're better off just going with
develop could give it a name here e12 ok
also you might have noticed that my
screen is very dark this DWG file i
actually change it under file options
and under system colors instead of the
default or black-and-white i went with
dark background and that gives it a dark
background so you can see this easier
you could always change it back just
remember it's under file options once in
here you'll see that you have your datum
plane already created for your front top
and write what we want to do is actually
get those all centered the front plane
is already centered for us but we want
to actually focus on building the season
revolved feature so what you can do here
you could go to the datum the plane tool
here select for example this plane right
here which is the right plane actually
I'm try this is the top and then you'll
see a little . in here on this DWG file
you're not always lucky enough to have a
center point but if there's arcs and
things are usually there so you can go
ahead and you can click on that and you
actually see it this case click align
itself depending upon which you select
you're going to get different effects we
click on this holding ctrl you want to
line it too plain for the top plane
you'll see will offset so i had to hold
ctrl and select both . and plain it ok
now we'll go back to the plane tool
again select the right plane and this
time
hold ctrl and select that point that you
have there and that will create a plane
that's offset dead center
ok i usually recommend just hiding these
older planes like the right plane just
right-click on it actually click on it
once the left mouse button then
right-click and hide do the same with
the top plane here click once left and
release right click and hold down the
right mouse button for a good second or
so
ok now we have our planes all
centralized now we can actually get down
to business here with geometry what I'm
going to do is I'm gonna go right to
revolve now you could start a sketch and
happy the geometry then go to revolve
I'm gonna go with the revolve method
here click on that
select this front plane start your
sketch
ok now i'm gonna go and like some rap
the references tool here and select this
plane right here as a reference on one
and now we can go ahead and use the
project tool and we'll go with loop
sometimes you get lucky with loop and it
goes and carries it self around in this
case I i tested earlier and it didn't
really work that well or even chain
sometimes you get lucky
it depends on the geometry that's
important in this case just go along and
select the geometry around there until
all changes color and you can see you
convert it
you can also convert this soul and stay
here
actually I . that actually
it closed hit OK and now we just have to
select that little blue line there to
revolve around and it's just recall the
geometry now sometimes there's gaps
depend upon the geometry that you have
those little gaps between it and you
might have to fix that by trying a new
line in or something you'll see that
just a few moments what you do when you
get geometry that's bit sloppy of older
cats system our legacy system and how to
work with but in this case it worked
pretty well we can see it recreated the
geometry as we liked it so we just hit
the green checkmark to apply there's our
wheel now what we're going to do is
we're going to try and take one of these
little cutouts here and copy it over
onto the surface so we can cut through
it
this plane so let's begin first select
the front plane and start sketch what we
need to do is we're going to actually
try and copy over the geometry using the
project cool project you can just do
single this one doesn't change to either
of these are splines actually cancel
there for a second i'm going to show you
sometimes splines could really be a
challenge to work with not too bad but
basically if you want to know what
you're dealing with you go to analysis
you can go to measure and like for
example if you go to diameter you'll see
that anything that's a radius or
diameter highlights it doesn't highlight
look it over here are here
that's an indication is probably spline
or polyline something something that you
traditionally might not want might be
difficult to work with but we're going
to go ahead and convert this job anyway
some of the zoom out
select that front plane again start my
sketch and now we go to project i'm just
going to select geometry and had closed
now
at this point we're just going to go
ahead and we can select the geometry
want so just click and drag fence
surrounding the geometry and you could
go up here to copy or you can hit
control C for copy i'll hit okay you
just leave it there for later in case
you like but over here now we want to
drop it on datum too so let's click on
data to and start sketch or you could
actually go right to extrude because we
don't want to use that challenge itself
i'm gonna go with extrude either way
it's fine
all right now if your geometry is laying
on its side remember you always have the
ability to right-click and you can go to
select orientation and select vertical
and you just like this vertical
centerline here it was laying on its
side rotate I think we're going to be
okay with this
so what we're gonna do now is I'm just
going to click and hit control V and
then click again and it should drop in
my geometry actually though its scales
and i'm not sure why it scales it by its
easy to fix you right up here is all the
data or information plumbing let's type
in one here for the scale factor so it's
equal to one to one basically now what
we can do is we could maneuver this
before maneuver it
let's see something this nice arc at the
top here that has a center point which
we knew was locked into the dead center
of the wheel over here you have a nice
enter reference to move entity click on
that now you can actually click on these
Plains here and then you have the
ability to rearrange this time i was
able to click right on the point here
it worked for me by them fortunately
here not get so you might have to do a
couple of the world thanks to get that
to highlight in the meantime we could
actually use dimensions such
you have the ability to drag it as well
oh there we go if you drag this around
you'll notice that it only moves certain
area selected I click on this vertical
will move up and down actually does move
to but the intention is to get this
actually located right here and let's
come to sketch here and see if we could
answer reference just gonna quit out
first select some references just get a
center point here in centerline let's
try that again I'm gonna go ahead and
hit control V to paste click on it set
it back to one
all right here we can see it has the
ability to move let's try and get that
in here
ok just by maneuvering around i'm not
sure why this did this but it did snap
center . now I'm able to click on it I
think maybe it might be because it was
on the surface model regardless i'll try
that again basically now you can see you
can actually snap it to the center by
grabbing that center . once you select
this entrance to move in your looks like
that . i think what was the problem was
that i was actually the surface wasn't
selected to 1st move it out of the way
and now it's locked in at this point you
can try and extrude or you can hit the
check mark since we've got a lot of
places now you see this flying points
this is where it gets a little flop
because basically it's not necessarily
creo that's issue so much as it was a
geometry that you brought in cad system
translation it works well and here if
you see I try to extrude it
I don't get into options so there's
sometimes some cleanup you have to do
here so we're going to go to the baby
button here and I'm gonna go back to
front front right
ok and I'm going to change some of these
from types of splines to click on the
spline delete and I could use as the art
tool i can click on this . drag it
directly to the left will bring up a
tangent arc connected pop I'm going to
middle-click just get out of that tool
click on the spline Italy don't just
click on the flight . actually do the
same over here and bring out the ark now
the middle click here now we can see we
have the shaded geometry so apparently
there might have been a little distance
gap between those clients but we're not
quite done yet here we want to ensure
that these are smooth most likely they
are tangent so we're going to go to the
tangent tool up here we're going to
select the spline and the
make those two tangent as well as
supplying their kind of sight to see
little teeth appear for tangent now we
can rotate a little bit they extrude it
ok they're all right now at this point
if this is going to be a cast wheel you
probably want to add draft extreme and
it's easy enough to do over here you go
to options and there's ad paper to be a
taper unfortunately up at that point you
can only add on one side I'd like i know
i like to use it on both sides and cut
the same time it's a limitation 30 here
but we can add the tape remember c'mere
feature over to the other side was cut
but we're not gonna be able to do that
so I'm not going to have the tape right
now just to keep it simple
I'm gonna go in this case both
directions
make sure you select remove material and
hit ok now there is also through all i'm
just going to keep it easy though I know
it's gonna never going to get thicker
than seven inches pretty safe to say
okay all right at this point we're going
to go ahead and add some champers
sources chapters have . 25 select this
edge here this edge checkmark you can
see the yellow geometry starting to
pierce through from the section that was
on the original drive and that kind of a
kind of flexion know you're on the right
track you're doing it right
ok now finally we're going to go ahead
and pattern this now if you know this if
you try and we've learned this before
with patterns you have to hold controls
both features camper and extrude and
then right-click and group them together
now you can use pattern tool that
dimension will use axis select the
center axis that's where we're going to
put in five instances and 360 degrees
divided by five 72 degrees space it's
green checkmark too
and there you have it if you just want
to verify again you can see the yellow
geometry person through that's a good
sign but that your got cracked but if
you want even check further go to view
go to section and select this from plane
like a section through and just verify
that the original geometry is all
alignment and it was done to customer
specifications
now remember sometimes trying to scale
differently so if it's like one half
scale you have to be aware that you're
going to scale this appropriately inside
30 more scalable try and that concludes
