In this lesson, we'll be adding a post to the bottom of the stairs with a goose-neck that rises to attach to the railing. A goose-neck, for those of you who don't know, is a railing extension that curves upward or downward to tie the main railing to a post. We're going to load a predefined family into the model, which happens to be a post with the goose neck cap. To place the post, we'll need to cut a section through the staircase, then change some parameters. Of course, changing the material to reflect both cherry and walnut will be the finishing touches. To get started, open your revit file, called landings and railings, and follow along.
The first thing we need to do is load the family into our model. To do that, go to the Insert tab and click on the Load Family button. Browse to where you've been keeping all of your parts, and find the file called Post Up. Once you've found Post Up, click Open. What I'd like you to do now is go down to floor plan level one. We need to insert the post into the bottom of our stair. Go to the Architecture tab and click on the Component button.
You will see our post up. Let's get an offset of 6 5/8. 'Cuz we know that's how high our landing is. Move your post over to one of the angled lines, and once you see one of the angled lines, hit your Spacebar. Hit your Spacebar again, and it's going to rotate the post into the direction of the railing. You don't need to be exact, but you can kind of eyeball it, put it right about here. Hit Esc. Now what we need to do is be a little more precise and cut a section and move this over to the railing.
To cut a section go to the quick access toolbar which is on top of the tabs and click on the Section button. To place a section is a two point process. We pick one point and pick another point. Then we can say what direction it's going in. So, to place a section, click this first point, zoom out a little bit, and eyeball it as much as you can to line up with the stairs. Click the second point. Hit Esc a couple of times. Now, to open the section, just simply double-click on the bubble, anywhere on it, and it'll open the section. This has a section through our stairs.
We see that we have a bit of a gap here. What we need to do is close that gap in. We're going to select our railing and click the move button. We're going to move it from this very tip down to this tip. Our railing is now perfectly in place. Hit Escape. I need quick access toolbar, go to a default 3D view. Zoom in on the railing and see that it's mounted perfectly. The last thing we need to do is of course alter the materials. Go ahead and select your post and scroll down until you see material, rail material.
Click into the bi category field. Click the Builder button. The rail material will stay as walnut. Click OK since that's the default. The post material, let's make that cherry. Type Cherry into the search dialog, and then you can pick Cherry. Hit OK. Click off of the railing, presto. Go to the level and floor planner again. We now need to mirror this to the other side of the stairs. To do so, go ahead and select your post and click the Mirror Draw Access button. Pick the mid point of the landing and draw a line straight up perpendicular to the stairs.
Once you see the perpendicular snap show up, pick that point and hit Esc a couple times. Go back to a 3D view, and your stairs are now perfectly aligned. So, what is a set of stairs in RAD anyway? It looks to me like it begins as a generic staircase, then as we start building it with our parts, it takes the form of, well wherever we want, just like in construction.
