Hey, guys, this is Aaron. Later on this week we have a video coming from Joshua Cohen,
and his 3D Basecamp 2018 session. Joshua has some awesome information to show you guys. He
does some really cool stuff with SketchUp. He does a lot of visualization and crime scene analysis,
but you'll just have to come back and check it out. He also shows SketchUp used in a lot
of different ways. One of the things that he does is he uses watermarks and photo match and
images. I thought it might be kind of good to do a review to talk about those three different ways
of bringing in imagery, how they're different, and which ones you should use when. So, that's
what we're going to do today. We're going to hop in right now. Okay, so I have a blank file right
here. We're going to start with the simplest one. I'm going to go up here to "file" and "import,"
and I'm going to choose this image. I just took a picture with my phone of the office. I'm going to
import it as an image. When I import an image, of course, I bring in that file and I pick a point
to place it. I can drag to scale if I want, or if I double-click it, it will come in as the default
size. I'm just going to place it right there. And that will make my image into a group. An image is
different from a face. It's not a face, it's an image. It's a special thing. If I pick on it and
look at the info, it tells me I have an image. I'm going to go ahead and use "rotate" to spin this
upright. So, we can look at it. This image is one surface. If I come in here and start drawing on
the surface - say I want to outline this painting right here - I can come in here and click on it,
and what I'm basically doing is I'm drawing on top of the surface. There is no depth cue. It's
not going to tell me where a surface theoretically goes backward. It's only going to tell me that I'm
on this flat surface, this flat face. And if I do draw something like that, what I've just drawn is
a shape sitting on top of that surface of the image. So, an image is basically like bringing
a poster into your room. That's it. It's a flat surface. It's done. Now, there are some things
that you can do with "image" which are kind of nice. One of them being, if I take these lines
back here, I can select an image right-click and explode. When I explode it, it will take what was
formerly a grouped image and it's going to explode it. I'm going to get four edges and I'm going to
get a surface. Because I just put these four lines around the painting, when I explode it,
it will intersect that geometry, and I actually have that broken now. I can, option, and copy that
out. One of the things I can do with an images is I can actually explode it and select pieces of it
to use elsewhere. So, I can actually chop this up for parts that I could use inside of my model. So,
that's one thing. That's one option, kind of a neat option to have. The other way I can import
an image, the same exact image, I can turn on "use as matched photo". So, we've done other videos
on this. You guys have probably seen this. What I could do is use these handles right here to align
vanishing points; so parallel lines in a drawing like this would line up with the top of the wall
right there and the bottoms of these paintings. I am making the assumption that these paintings
are straight. By doing this, put this one right here, this one we'll grab and put it up here on
the ceiling, and then put the second one on the bottom of the other painting. When I do this,
I can create, or basically fake, a 3d space that I can model inside of. That is pretty close. I
am going to fine-tune that just a teeny bit. Get that lined up a little bit better. When I'm done
there, I'm going to go ahead and remove mark now, I can actually come back here and draw in the 3d
space on top of those lines. I can actually create lines that move within 3d space. So, it looks like
I'm tracing on the 2d image, but I'm actually, as I'm drawing, creating the space in 3d,
and with the help of this pretend vanishing line. Now, if I orbit or change any view from this
current camera view, my view goes away. See that? What it did create was this scene right here. So,
if I click on it, it will bring my image back, and it will put my drawing in the same orientation it
was in before and take me right back into that reference image. So, I'm now drawing overtop
in 3d space, so this is kind of a fake image there. It does, like I said, create this scene,
so I can always jump back to it. So that's photo match. Photo match works really well if I have an
image like this where I have good vanishing points and I want to convert that 2d image into a 3d
space. Another way to import an image as reference is separate from photo match or import image, and
that is using a watermark. A watermark is actually part of your styles. If you go to "styles" and
go to "edit" a style, this fourth tab here has a little tiny "ok" on it, is your watermark. Here,
I can hit the "plus" to import an image as a watermark. Grab the image I want to use, and
say "open." What it will do then is place it right in the middle of the screen, as big as it can get.
I have the option of putting the background - that means it is going to fall behind my geometry - or
I can choose overlay, which shows me something very similar to what I saw with the matched photo.
I am going to hit "next." I do have the ability to adjust the opacity. So, I can say this is over
the front, but I can adjust how see-through I want it to be. I'm going to hit "next" there,
and I'm just going to leave it the exact size it is. I do have the ability to position it, or put
it in a certain spot. By doing this, I've actually created something new. Because this allows me to
move my geometry in the 3d space without changing anything that is in the background. Remember when
we were in the photo match before, we were locked in to one view. This view will actually let me do
things like, alright I want to move this. So, let's see, we will maybe use the "pan" to shift
this down like this, and use the "orbit" commands to try to line that up. A watermark allows me to
align with geometry basically however I want. This is something Josh is going to show you in
his video. He actually goes into taking individual scenes out of a video, and aligning geometry with
them, which is really cool. It's a very cool way to do the visualization stuff that he does. So,
this is going to give you more freedom. I can move anywhere inside the model, and I'm not locked
down like I am with match photo. However, as you can see here, what I don't have is that good 3d
inferencing that comes along with a match photo. Right now, I'm trying to guess and line this model
up. This may not be the perfect way to do it, if I am trying to exactly match geometry. Whereas,
if I am just coming off the ballpark, or am being inspired by an image, a great way to do it is with
watermark so I am not tied to a specific view. There we go. That's a little snapshot - that
was an image joke - on importing an image using match photo or watermark. Any of the three can be
used at any point in a model, in fact you can use all three of them in the same model if you needed
to. Image, like I said, is great for bringing in graphics you want to use inside your model; or you
want to trim them and just use certain pieces, bring them in as an image. If you have a good
image with perspective, and want to actually match it with those perspective tools, the ability to
use tools inferencing and that sort of thing, then match photo is great. Watermark is just a good
way to throw a reference down on your screen and you can draw on it however you want. I sometimes
use watermark where I will nestle it over on the side of the screen; maybe I'll even put it on top,
so I always have that image there to reference as I'm doing modeling. It's really up to you how you
want to use them. How do you use them? Do you use imagery, or did I miss something? If so, leave a
comment down below and let me know what I should have included. If you did like this video, give us
a like. If you subscribe, you'll be notified when Josh's video comes out on Friday, and when all the
rest of our videos come out. Like I said, the most important thing is comments. Leave us a comment
and let us know what you thought. If you thought there was something we could do better or you
think of an idea you think would make a good Skill Builder video, tell us all about it. I like making
these videos. I like them a lot more if they're showing something you want to see. Thank you.
