Join Eric Wing for an in-depth discussion in this video Adding a rooftop unit, part of AutoCAD MEP Essential Training.
Let's work from the roof down, shall we? Since we are actually taking advantage of 3D, we might as well actually set a unit up about 40 feet in the air. What we're going to do in this video is add what is called an MV Part. This MV Part will be a roof top unit. First, we'll make sure we're on the proper workspace. Then, by going to our HVAC Tool, we'll select the Roof Top Unit to place into our drawing. We will then look at the unit in 3D and make a height adjustment. To get started let's jump into our MEP mechanical model. Let's go down to our work space switching.
I'm going to click this fly out here. And I'm going to make sure I'm set up for HVAC. You may have to make some adjustments to your tool palletes. The next thing I'm going to do, is I'm going to zoom into this area right here. I'm going to go to my tool palettes HVAC, I'm going to come down and find my equipment tab. I'm going to scroll down on my equipment tab, I'm going to come all the way to the bottom and I'm going to find a roof top unit and I'm going to click it. Our part size, 3.5 ton roof-mounted gas-fired A/C unit. Notice that we have a lot to choose from. We can just select a default, for our purposes here, but if you want a different kind, go ahead and select one you like.
I'm going to stick with 3.5 ton roof-mounted gas-fired A/C unit. Our elevation is 12 foot 7, but we can change that after we place it into the model. Now just click into the screen once. Let's pan over. And I'm going to put it right about here. We can specify whatever the orientation is going to be. I'm going to lock it to zero. And I'm going to pick this point right here. Then I'm going to hit escape a couple times. Go ahead and select the unit itself. Let's look at the properties. It puts it on the correct layer, knows what type it is, what sub type, the name.
These all come in handy when we're looking to schedule something. If we go to extended data, notice that there's not a lot here. Once we tag this item, you will see this will be populated with a lot more data. But the unit's still selected. Hold your shift key down and your wheel button. This will focus only on our RTU. It's high up in the air, but not as high as I'd like it. I'm going to pan around to this view so I can see it. Hit escaped a couple times. At your command prompt type in S-H-A-D-E, shade. This will allow you to see your unit a little better.
The architect doesn't have a roof here but that's okay. We'll just raise this up to about 40 feet. Go ahead and select your multi-view part. Go to the properties. Go to the design tab. And for our elevation, let's type in 40 feet. And hit enter. Now our unit's well above the roof. Notice that we can move it up or move it down as we please. Let's move it down another ten feet. Or what we can do, in 3D, we can look at this straight on. On your view cube, click your front button. It will focus right in on our item.
Notice we can see this and the roof a lot cleaner. With my RTU still selected, I'm going to drop the elevation down to 30 feet. This puts it just below that roof level. That's about where I want it. Let's hit escape a couple of times. Now on our view cube, let's go ahead and click the top. Notice that the difference in the shading, when we go back down to our plan view, our NEP design takes over. Being able to browse through a catalog sure beats inserting a 2D block into a drawing that doesn't really look like the unit you're trying to use
