In this video, author Shaun Bryant shows you how to leverage the 3D graphics support in the AutoCAD 2018.1 update, commands; 3DORBIT, ZOOM, PAN, and VSCURRENT.
- [Instructor] Welcome to another tip and trick for you guys to use when you're working in AutoCAD. Now, this particular tip and trick applies to AutoCAD 2018. In fact, AutoCAD 2018.1 to be specific. Now, if you're running your AutoCAD on subscription and you're running AutoCAD 2018 you will have been given the .1 update for AutoCAD 2018 making it AutoCAD 2018.1.
Now, basically that update has given you a few new features and a few feature enhancements. One of those is 3D graphic support, so what I've done is I've given you a nice drawing. It's called Fixtures Model.dwg. Again you can download that from the website, use it to follow along with this particular video. So, you can see it's obviously a 3D building and we've got some walls there, we've got a curtain wall, got some windows, some doors, some openings and so on.
Now, the 3D graphic support applies to a compatible video card that you're running with AutoCAD and ideally you want to be running it on Windows 10 as well so you should have possibly updated to Windows 10 as well, and I'm not going to tell you what to update to in Windows because I know it's very much a specific thing. It depends on your IT department, it depends on your company policy and so on and so forth. However, let's jump down to the status bar and you'll see a little blue circle there.
It looks a bit like a sort of speedometer or rev counter in a car. If you hover over it, it will tell you that your hardware acceleration in my case is on and it's the graphics config variable there. Can you see that? If you right click on it, you can go to Graphics Performance there, click on Graphics Performance and it brings up the Graphics Performance dialog box. So, you can see on my particular laptop I'm running an NVIDIA GeForce GT 750M graphics card and there's my driver version and my virtual device is DirectX 11 and I'm running just so you know, Windows 10 as well.
So, you can see that my hardware acceleration is on. Now, if you're running what we call a modular graphics card such as NVIDIA, or an AMD, and so on and so forth, you want to be running the hardware acceleration and if you're running a good PC or laptop, it should have a modular graphics card, separate graphics card, sometimes known as a GPU, a graphics processing unit rather than an integrated card that is build into your motherboard of your PC.
Now, I don't want to get too techie on you but basically your graphics card and your motherboard should be separate, they should be modular, two separate elements within your computer. They're more effective that way because you've got specific things on the graphics card that allow the graphics to perform to a better performance level than they would if it was integrated onto the motherboard. Now, my hardware acceleration is on and as it says there, disable hardware acceleration only if you're experiencing graphics issues or have an incompatible video card.
So for example, if you're running an integrated graphics card that was built into your motherboard, you might switch off hardware acceleration because it might slow down your PC or your laptop. Now, I want to go into the 3D graphic support, so you'll notice that I've got hardware acceleration on and I've got all my boxes ticked. So, I'm using high-quality geometry, smooth line display, advanced material effects, full shadow display, per pixel lighting and uncompressed textures.
So, all of those facilities are available to me because I'm running my nice NVIDIA GeForce GT 750M. Now, AutoCAD 2018.1 has enhanced the graphics performance in 3D, so all I'm going to do here is click on OK, all of my setting are what I want them to be and I just want to show you a couple of AutoCAD commands where this 3D graphic support is much, much better and it's always better every .1 update or every software update, so for example, when we go to AutoCAD 2019 next year, you'll find that there will be some 3D graphic support again and they're always improving it.
So, let's do a little 3D orbit. Now, I can do this in a number of ways. I can hold down the shift key and I can then hold down the wheel on the mouse and there's my little orbit symbol and as I move, can you see that's really nice and clean and smooth? And that's the 3D graphic support provided by the .1 update and you can see that I'm moving around there and that's really nice and clean and smooth. Now, the jerkiness is me, that's my mouse moving. That's not the actual graphics card causing a problem. That jerkiness is me and the interface between me, my mouse and my mouse laptop.
Now, I'll just release the shift key and the wheel there. Now, the other ones are just literally zooming in and out. If I hold down the right-hand mouse button, just right click, you'll notice I've got zoom and pan there, so I'm going to click on zoom. Now, this takes me into what they call real-time zoom, so get a magnifying glass and then I hold down the left-hand mouse button and I move up, see the little plus sign? I'm zooming in and then I move back, minus sign, I'm moving out but look how clean the graphics are as I do that.
The graphics are always staying nice and clean. So, if I right click in my real-time zoom, I can jump into something like pan or I can exit if I want to and so on, so I'm going to exit everything and then I'll right click again and jump into real-time pan and there's my little pan symbol. If I hold down the left-hand mouse button, I'm gripping the drawing and I'm pulling the drawing left and right moving the mouse. Release the mouse button, click on it again and hold and move up and down and I'm panning up and down but can you see the graphics are staying nice and clean and that's that 3D graphic support, so I'll then just right click and you'll see I can exit the pan mode there like so.
Now, it's predominantly 3D orbit and obviously zooming and panning the Autodesk I've worked on for this .1 update for AutoCAD 2018 but having that nice, clean graphical view there in front of you in the drawing area is really important, so if you have got AutoCAD 2018 and you haven't updated to the .1 update yet, you should because it will improve your graphics as you can see and it means that you've got a better graphics performance when you're working with your AutoCAD.

Q: Why can't I earn a Certificate of Completion for this course?
A: We publish a new tutorial or tutorials for this course on a regular basis. We are unable to offer a Certificate of Completion because it is an ever-evolving course that is not designed to be completed. Check back often for new movies.
