- [Instructor] We're staying in
our new metal plate .dwg file.
And I've left us zoomed in
on the section view and the side view
that we were working on in the previous video.
The reason being is I want to show you a really nice feature
in AutoCAD called the Revcloud command.
You use it for revision clouds in your AutoCAD drawings.
So if you go to the home tab on the ribbon,
go to your layer drop down in the layers panel,
you'll see we have a revision clouds layer.
Select the revision clouds layer
so that you're placing your revision clouds
in the right place and on the right layer.
Very important that they're on the right layer.
Now, when you're placing them in the right place, though,
you've got to think about
where you want to put your revision clouds.
I often put my revision clouds in the layout tab
and I'm going to show you exactly why,
and I'm going to do some fairly radical revision clouds here
just to demonstrate how this works.
I'm going to zoom out slightly from the view you like that.
And then I'm going to go to the draw panel
on the home tab on the ribbon,
and I'm just going to hit the fly out there
and just pin it open because revision cloud is right there.
So if I click there
I've got various types of revision cloud that I can use.
I've got a rectangular, I've got a polygonal one,
and I've got a freehand one.
So I'm going to do a rectangular one.
So if I click on Rectangular
and I need to specify the first corner point
I can pick and drag like I would a rectangle
when I'm drawing a rectangle
but what we're going to do first
is we're going to right click and go to arc length
and just make sure that our arc length
is set to a sensible length.
Now, if you look at the dimensions there,
you can see we've got one to five and 250 and so on,
I would go for an arc length of about 60 there,
maybe even 50.
So if we go 60 and press Enter, what that means is now
is I can click my first corner point and drag.
And can you see, it's a sensible revision cloud.
The actual arcs don't look too small or too big.
The last thing you want is a revision cloud
with really tiny arcs
and it just looks like a rectangle almost.
So there's our revision cloud.
Now I've placed that in the model tab,
let's go to my sections and elevations layout tab
and see how that looks in the view port.
I've just made it by the skin of my teeth, you'll notice.
Can you see that just fits inside the view port.
Now, what would happen if I was outside the view port.
Let's go back to the model tab
and I'm going to delete my Revcloud.
I'll just hit the Delete key there.
I can right click and erase if I want to.
Let's go for a different type of revision cloud.
So let's click on the flyer,
I'm going to go for polygonal this time.
So that means I can create a revision cloud now
using any type of polygonal shape.
Right click first though, arc length
just check that that's still at 60.
Press Enter if it is to accept the 60 value,
if it isn't 60, type in 60 and press Enter.
Now I'm going to do a really radical,
random, weird revision cloud.
I'm going to start down here and as you can see,
I'm going all over the place, really big,
coming in close here like that.
And there's my weird random revision cloud.
I'll press Enter to finish like so.
How does that look in my sections and elevations layout tab?
Well, as you can see,
it goes well outside the extent of the view port
in the layout tab, not quite what we want.
So I'm going to jump back to the model tab
and I'm now going to select the revision cloud
and I'm going to right click and erase it, like so.
What about that last revision cloud tool?
What was that one?
It was freehand.
Wasn't it? If I remember rightly, there we go.
There's the freehand one.
So this will create a revision cloud
using a freeform polygon.
It's often quite useful when your views are quite tight
in smaller view ports, which is kind of where
we need to go in this particular case.
So I'm going to click on freehand
and come into the drawing area.
Right click check your arc length, always check it
when you place from revision cloud.
It's still 60, so I can just press Enter there.
And now what I can do is I can just literally start clicking
and working my way around the shape.
I can be really accurate now
using my little cross hair there, my cursor,
I can go around this and be really, really accurate.
Can you see that?
And I can get in nice and close to the text, work my round.
I'm just clicking away here.
Just lots of little clicks and you can be really specific
about where you want your Revcloud to go.
And then all I got to do is just move towards the end,
Enter to finish, automatically closes it for me.
I've then clicked one extra time on the mouse there.
So I'm trying to do a selection window,
I'll just hit Escape to deselect that.
So as you can see, that's a really tight
neat and tidy Revcloud.
If I go back to the sections and elevations tab now
that fits beautifully in my view port in the layout tab.
Now here's a thought for you,
Revclouds don't have to be entitative,
all they are is an indication
of something that you need to highlight on a drawing
where something's changed.
The next revision of the drawing is shown
with the Revcloud.
So you could possibly put some text there as well
and possibly even a leader line
or something linking to the Revcloud.
But at the moment the Revcloud there is in the model space.
So if I go back to the model, there's my Revcloud there.
What happens if I delete that?
Right click, erase like usual,
and then go back to the layout tab
and on the revision clouds layout
I place the revision cloud in the layout space.
There's nothing to stop you doing that.
It's very much a choice
or possibly a CAD standard that you're working to.
So what you could do here is put the Revcloud
in the layout tab.
I will show you some caveats for that though.
So let's go back here now to,
we'll just do our rectangular revision cloud this time.
Right click and remember your arc length.
Now, remember this is at one to two scale
so ideally I need to make my arc length smaller.
So I'm going to go with something like 25 this time
and press Enter.
And I'm just going to click drag my little rectangular
Revcloud like that and click again.
Now that's great and it's in the layout space
so I can select it in the layout space like that.
I can also use the grips to resize if I want to.
I'm just going to hit Escape though, to deselect it
because something could happen here
that could really mess up this Revcloud placement.
If I select the view port and I unlock it
and I perhaps change the scale of the view port
to say one to four, can you see what happens?
The view port is now not showing exactly what I want
nor is the Revcloud.
The Revcloud is kind of a bit too big.
So what I've got to do here
is I've got to obviously change the scale back
to one to two for a start,
just get that back in there like that.
And then what I also need to do is make sure
that I lock that view port at the one to two again.
Hit Escape to deselect.
And what I would do is if you are going to use Revclouds
in your layout tabs
just be aware that obviously the view port scale
could change in the layout tab at any time.
So it's sometimes better not to put the Revcloud in there.
I'll just right click and erase that.
It's often better to do it here
and use something like the little freehand Revcloud
that I showed you.
So if I do another freehand one, and then I right click
and go back to the arc length that I wanted,
I'm going to go with 50 this time
just to be a little bit different.
And then what I can do is I can start here
and be really really accurate with my Revcloud.
Now I've just place that slightly over
doesn't look quite right.
So if that happens, just hit Escape a couple of times
go back to the command, back to freehand,
right click on arc length, always check,
Enter to confirm the 50.
I'm going to up there
and just start coming around my little section view
and side view again.
And again you can get this in nice and tight
near the text like that.
You come around, come around the dimensions
and it's lots of little clicks like that.
And you'll notice, as actually drag,
I don't even have to click anymore.
Isn't that clever?
There we go.
Back to the sections and elevations layout tab
and that fits really nicely in our view port
but it's in the model tab.
You'll notice there,
I did crossover ever so slightly with my arcs there.
Obviously you want to try and avoid that.
That's something that can look a little bit untidy
if you keep crossing over with your arcs
in your revision cloud.
Let's go back to the model tab
and you can see there that our revision cloud,
our little freehand revision cloud looks nice and neat
in the model tab as well.
