- [Instructor] We're staying in our 3dhouse.DWG file.
And as you can see, I've left it all in the same state
as it was at the end of the last video.
So we're going to do a little bit of housekeeping
because what I want to show you now
is how to generate what is called a 2D flat shot
of your 3D model.
And it's a really useful tool
if you just want to generate some 2D views of your 3D model
quickly and easily.
So make sure you go into the top viewport here.
And what I'm going to do is select the section plane
that I created.
Let's just delete that so that everything kind of goes back
to normal.
And then we're going to go up to the view panel here,
click here and I want a single viewport.
That should take you back to your top view
that you had selected as your viewport a moment ago.
So what we're going to look at now,
is how do we generate this flat shot?
Well, you can see at the moment that we're in the top view,
now that's a pretty mundane view.
You might want to generate a flat shot of that though.
So let's work with that first,
make sure you're in the top view on the view cube
or on the view control here.
And again, this is where parallel is really important.
And if it does fill the screen a little bit,
just roll back on the wheel or notch just to zoom in or out
like that and obviously pan it to sit it centrally.
Now I'm going to move my top view.
I'm going to pan hold down the wheel
and move across like that,
because I want some space over here to place my flat shot.
Now, one of the things that I always do
is generate a new layer for my flat shots as well.
So layer properties in the layers panel,
and we're going to jump to new layer there,
and I'm going to call this the 2D flat shot layer.
Now I'm going to leave it as white in this case,
you could make it a gray,
but ideally you want to make it a color that stands out.
So I'm going to leave it white like that.
And then what I'll do is I'll double-click
on the little sheet of paper there to make sure
that 2D flat shot is my current drafting layer.
Now flat shot is quick and easy to generate too,
because you just go to the home tab on the ribbon,
into the section panel and click on the fly out.
And we'll just pin that open.
And there's our flat shot command there.
It creates a 2D representation of all 3D objects
based on the current view.
So if I click on flat shot now,
I can insert this as a new block.
I can replace an existing block.
I can export it out to its own DWG.
Foreground lines are color by block,
I always set that to by layer.
And then any obscured lines,
you can show those or not show those,
it's entirely up to you, but something you can do here,
which I quite like doing is I'll do it by layer,
but I'll change the line type.
So I'll give it a dashed line type, for example,
and I can include tangential edges if I want to.
We don't need to cause there's no real curves to worry about
it in this particular case.
But when I click on create, there's my snapshot and look,
I've got those lovely dashed,
hidden detail lines inside the property itself.
So I can click there and enter the X scale factor.
I can scale it if I want to.
So I'm just going to go with one each time.
So use the X scale factor one for the Y scale factor,
rotation angle zero and we'll leave it at zero
and just press enter to confirm.
And there is our 2D flat shot
and it's just an AutoCAD block.
Now the lovely thing is because there is an AutoCAD block,
I could explode it if I wanted to and work on the detail.
I'm not going to though,
but one thing I can do is I'll just
unpin that there like so, is I can now move this.
So I'll select it, move, pick a corner.
If line that in with that and just drag across a little bit
that is now lined in beautifully.
So not only now have I got my 3D model,
but I've got a 2D flat shot of that roof as well.
So if I just hit that corner
and go to the Southwest isometric,
there's my nice flat view that I can work with.
And I can add some dimensional annotation to that as well.
But the benefit I've got with a 2D flat shot is
that I can go to elevations 3D here
and I can create another viewport.
So let's just jump and make sure
that the VP layer is available, the viewports layer.
There it is there.
So what I'll do is I'll make this one smaller,
pop that up there, double click in there,
double click on the wheel, zoom extents and you can see,
look, there's my flat shot there.
So what I want to do here is ideally zoom in a bit,
pan across, so there's my front view that we had earlier,
but what I'll do now is I'll create another new
rectangular viewport.
And in the layout view ports now,
I'm just going to pick a random
sort of rectangular shape like that.
And what I can do now is I can jump into here
and what I can do is I can change the view.
Like so, flip that round, turn it around a little bit,
using the view cube, zoom in here.
And I've now got a 2D plan view as well.
So not only have I got my 3D views,
I could change this to something like an isometric.
Let's go back to the good old Southwest isometric view.
I can change that.
I might need to move that a little bit perhaps,
but can you see where I'm going with this?
I can generate 2D snapshot information very quickly
and easily using my flat shot command.
Now obviously, if any changes are made to the model,
they're not going to reflect in that until I update it,
but there's a trick there as well.
If I jump into the model tab here,
what I can do is I can select this like so.
Now I can replace this very quickly and easily.
So if I go back to, let's say the top view here, like so,
and I jump in here and I go to flat shot again.
So I can replace the existing block, select it.
It's there like so I want to replace that one
and I can then go foreground.
I want to change the color again, I want it by layer.
Now remember, we need to just make sure
that we're using the right layer here.
'Cause we're on the viewports layer.
We don't want it on the viewports layer.
We want the 2D flat short layer, remember?
so I'll jump back here, go back to flat shot,
like so replace existing block
and select my flat shot block there.
Color, I'll go by layer, obscured lines show by layer again.
So we want by layer and we use that dash line type,
click on create, and that will update for me.
So if I've made any changes here in the 3D model,
I can update them in that block there
just by creating another flat shot.
Very quick and easy, but also really useful
because that 3D model is now allowing you
to generate 2D geometry,
that you can add your dimensional annotation to.
