Skill Level Beginner
In this lesson, we'll be adding railing extentions at the bottom of each stair for floors one through four. To accomplish this, we'll be adding a component or a family in Revit-speak, to the bottom of each stair to create a 88 compliant landing. The file we'll be using is provided for you. It is called ada-pipe.rfa. By introducing a predefined family to the model, we can gain control over the size and aesthetics of how our stair railings terminate at the bottom step. Revit does allow you to make modifications to the top rails for adjusting railing extensions.
I'd like to look at a more precise application. We'll be loading a model and using reference plans to locate the family in alignment with the angled railing for termination. To get started, open your Revit file called U-shape stairs and follow along. Take a look at the 3D view to see what we're going to accomplish at the end of this lesson. We'll see at the bottom of each railing, we have a family. That family is the ADA-Pipe family that we're going to load in a moment. As you can see, we have different adjustments that we can make independent of the stairs.
This allows us to get in control over the model. If you could, in the Floor Plans, please go to Level 1 and zoom in on the bottom stair. What we're going to do now is create a reference plane to locate the face of our ADA compliant railing. What I'd like to do is, on the Architecture tab, click the Ref Plane button. Once the Ref Plane is activated, click the Pick Lines button on the Draw palette and give it an offset of 9 and 1 half inches.
(audio playing) Come down to the very bottom thread, and once you see an alignment line appear to the left, go ahead and pick the bottom stair. Hit Escape twice. Select the Reference Plane and stretch the top grip up and stretch the bottom grip down. We now have a location for a family. Go to the Insert tab. On the load from Library panel, there's a Load Family button, click it.
Browse to the location that you put the file called ADA-Pipe. Select ADA-Pipe, and bring it into your model. Go to the Architecture tab and click the Component button and it will begin to place. Zoom in on the front of your stairs and hit the spacebar once. Bring the railing close to the railing that's on the stairs, and you'll see that it will snap into place. Click the nearest button then hit Escape twice.
In your project browser, please go to the south elevation. What this does is this gives us a good look at our railing, to see how far we need to extend it in. Select the railing. In the properties of the railing, scroll down to extension and type 10.5 inches. (audio playing) Hit Apply. This will extend your family to the existing angled railing on the stairs, creating a continuous join. Go to a 3D view just to check it out. Zoom in, we now have what we want, the extension coming down. If you could, please go to Level 1 Floor Plan.
Select the ADA-Pipe Family. Click the Mirror Pick Axis button, or your can type MM for keyboard shortcut. Click the Center Reference Plane. Hit Escape. Change your detail level to fine, just to make sure you're in alignment with these railings. Once you've verified that you are, go ahead and select, by control-clicking both railings, and copy them to the clipboard as you can see here. Once the items are copied to the clipboard, Revit will activate the Paste button.
Click the Paste drop down to go to Align to Selected Levels. I'm going to choose Level 2, hold down the Ctrl key, 3, and Level 4, and click OK. Go to 3D view and check out your railings. You now have a nice, safe landing at each stair level. As you can see, the power of Revit comes for the ability to insert a component or a family. And make adjustments to the component at any point with the needs of our current situation.
By loading a family into the model, we increase the efficiency in how we model a stair landing.
