Creating a mechanical VAV

- [Instructor] Okay. Let's make a mechanical VAV in Revit under families let's go to new. I'm going to scroll down to generic model. Let's click open. The first thing I'd like to do of course, is go to family, category, and parameters. Scroll down to mechanical equipment. Let's make this work plane based. For part type let's click into it as normal, normal works. Use diameter for round connector. I think everything else looks good. So click OK. ESC a few times. Let's make some reference plans. Let's right click on this reference plan and create similar. On the draw panel, click on pick lines. Let's offset two feet, left, right, up and down. And ESC a few times, let's dimension those. Equal dimensions, overall dimension to equal dimensions and one overall dimension. The ESC a few times, for this four-foot dimension select it. Let's click on create parameter. Let's call it length. OK. For this dimension, we'll call it width. Click OK. Now let's go to our front elevation. Now I want this ref level to actually be the center line of my VAV. So let's right click on this reference plane and you create similar. On the draw panel, click pick lines. Let's offset it one foot six, we can type in one space six and it will fill up the feet and inches up, and down. ESC a couple of time. On the measure panel, click aligned dimension. The one, two, three, point off of it. Click EQ. Now pick here, to here and pick a point over here. Select your three foot dimension. Click on create parameter, we'll call it height. Let's click OK. ESC a couple of times. Now let's go back down to our ref level. Let's go to create extrusion, on the draw panel, click on pick lines. First, we're going to lock it, and I'll pick all four of our reference planes, and of course we're going to type tr for trim and we're going to trim it up. ESC a couple of times, now let's click on finish. Let's go back to our front elevation, type al for align, select the top reference plane at the top of the extrusion, lock it. Put the bottom reference planes, set the bottom of the extrusion and let's lock it. ESC a couple of times. Now, what I'd like to do is let's add an extrusion here and this will host our duct connector. So let's go to create extrusion, on the work plane panel, let's click set. Let's click pick a plane and click OK. Now, if we hover over, one of the lines on this, we can get the face. So once you see the whole thing, highlighted, click it. Now on the create panel, let's click on a reference plane, on the drop panel, click on pick lines. For the offset, let's go to inches. Now, I want to put one here, one here, one here, one here. ESC a couple of times, we can drag these down a little bit. On the measure panel, let's click align dimension. Let's do the same right here. Let's equally constrained that let's go to here, to here. ESC, select the three foot eight. Click on the create parameter button. Let's call it duct width. Click OK, think you know what we're going here. Click on align dimension, here to here, here. Pick off of it, click EQ, dimension this, ESC, select that dimension. Let's add a parameter, let's call it duct height, click OK. On the draw panel, click on pick lines. Make sure it's a lot. We're going to go here, to here, to here, here. ESC a couple of times type tr for trim, going to trim these all out. Now, For the extrusion end, let's just go out, I don't know two inches. Apply. Now click finish. Let's go to a 3D view. We'll put a connector on there later. Let's go back to the ref levels so I can get my bearings. Let's go to our left elevation. Zoom into here. Let's go to create extrusion, on the work plane panel, let's click set. Let's pick a plane, let's click OK. Now let's hover over again, so we can find the entire box. If you can't find it, hover over one of these lines, hit your tab key. There it is, pick that. Let's go to our circle button, click on radius, give it a radius of, I don't know five inches. Pick a point like, right here. Just ESC a couple of times. Select your circle. Let's turn on center mark visible, then ESC a couple of times, type al for align. Hit this reference plane here, this reference plane and lock it. This one here, this reference plane and lock it. ESC a couple of times. Now on the measure panel, let's click the drop down here. Let's go to diameter dimension. Let's select this item. It's like the 10 inch, let's click on create parameter. We'll call it round duct size. Let's click OK. Let's hit ESC a couple of times, looks like our extrusion end is two inches, which is good. Let's click finish. Just ESC a couple of times. Go back to the ref level. Let's go to the right elevation, so on our elevations, let's go to right, now, this gets confusing so let's set our visual style to hidden line. Let's go to create extrusion. On the work plane panel, click set, pick a plane, hit OK. Let's select the box, now and create, let's go to reference plane, on the draw panels, click on pick lines. Let's offset a couple, let's go six inches. Set one to the left and to the right, ESC a couple of times. Let's dimension these, let's go align dimension, equally constrain them. These are going to be our piping connectors, click EQ. Put one here to here, click off of it. We just lock that, I don't need to have a dimension on there. Now let's go to circle, let's click on radius, type in one inch. Put one here, put one here. Hold down the CTRL key, select them both. Turn-on center mark visible and ESC, type al for align. And let's just make sure we align these so they don't move on us. Same here to here, here to here. Now let's go to diameter dimension, dimension this one ESC a couple of times. Let's go to create parameter. Let's go to supply, diameter. Set OK. Now let's dimension this one, add a label, look to return diameter. Click OK. ESC a couple of times. Click finish and ESC. Go to a 3D view. Now we got some good stuff here. Let's save this and in the next video we'll add our connectors and test it out in a project.
