Advanced Modeling in Revit Architecture elaborates on the basics of core elements in Revit, such as walls, floors, roofs, and curtain walls, and digs into specialized features such as in-place families, adaptive components, and the massing environment. Author Paul F. Aubin guides designers into thinking both in and out of the box, through discovering and applying industry standard best practices, employing creative and sometimes unconventional techniques and procedures, and finding ways to make models serve multiple concurrent project goals.
So as we continue to refine our design, I want to look at a couple of different approaches to the way that we've built form so far. Sometimes you can actually create your forms from a series of building blocks that you already have, sort of pre-made families. When doing that, it's often useful to have some reference geometry to work from so that you can get things in the correct place. So in this movie we are actually going to create that reference geometry and then in the next we are going to work from those building blocks or those forms. Now what I have on screen here is just a file that we ended with in the last movie where if you watched that movie you recall we deleted the large block over here that was a budding up to the residential neighborhood.
So let's pretend that the residential neighborhood association complained about the scale of our building. They weren't too happy about having this very large edifice budding up to all their residential structures. The design team has gone back and looked for a solution on how to satisfy that group and still maintain the design that they were trying to maintain the square footage and the other requirements. And they have come up with this idea of doing a series of townhouse like facades that butt up against the residential neighborhood, but is a little more sensitive to the style and the architecture they are in.
This is the backdrop or the scenario that we are going to use in looking at these two new techniques. To get myself started here, I'm going to actually borrow this series of Reference Lines right here. So make sure I'm getting just that rectangular form and I am going to go up to Copy to Clipboard or do Ctrl+C and copy those items out of this file. Then I want to go to the Application menu, go to New and choose a new Conceptual Mass family using the Mass Template.
And go back to Modify and paste Aligned to Selected Level. Now this is going to be important. Even though the level doesn't have the same name it's just called Level 1 because it's a default, the Align 2 is the important thing because as you can see, that rectangle came in at the same relative location to the insertion point where it came from. And this is going to be important to keep everything lined up when we pull them together. Sometimes it's easier when you're doing a design iteration to actually work off in a separate file.
You can do this because you are not sure if you like it yet, you can because you want to have two people working together on the team at the same time. And then later when you pull them together, you want them to have the same insertion points so that everything comes in, in the right spot. Now I'm going to jump over to the Level 1 Floor Plan, and it may not be that convenient to actually work at this orientation. There's another neat trick that we can do here, where I can toggle on down here on the View Control bar, the Crop region. And you can see it right there the crop region of this floor plan.
Now I am going to select that, and we can actually rotate the crop region and the result will be that the view with in the Viewport is actually going to rotate. So I am going to click on this, use my Place center of rotation, or tap my spacebar, and click it right there at the intersection between those two reference planes. And then if you recall we were at an 11 degree rotation in the Project file, but I actually don't want to work with the rectangle running long ways vertically up I actually want to run it horizontal, so I will take that 11 degrees and subtract it off from 90 and I am going to use a 79 degree angle here and press Enter.
It's a little counterintuitive because the crop region didn't actually rotate, what rotated instead was the image within the crop region. But that gives me exactly what I want, I use the grips here to adjust the size of the crop region, get it a little closer to the rectangle. Crop down, but I want to keep the insertion point in view, zoom in a little. And if you want, you can even hide that crop region when you are done. So that gives me a good starting point and it allows me to kind of design these townhouse facades in a rectilinear fashion, which maybe is a little bit more convenient.
Now to do this I am actually going to just use some model lines. So I am just going to take a line here and start drawing a shape. And initially, I am just going to start in the normal Revit fashion of sketch and then modify. And maybe I will go about that far for now. And use Dimensions to set them to more rational numbers. So I will go to my Dimension tool or press D+I, dimension each of these model lines that appear, dimension here in this direction as well, maybe a couple of those.
Now you could see some of numbers are nice whole numbers, but maybe I want to adjust them a little bit. So I might want this guy to be some other value and then perhaps this guys, maybe these two are the same size base or maybe those are going to be like 35 feet each. Then, come in to here, make some adjustments to that. And the design would continue to iterate. And you can imagine by keeping the dimensions there, it makes it really convenient for the designer to go in and fine-tune and tweak and make those adjustments as they make changes.
I could continue working on this one here, but actually what I'm going to do is instead of drawing this whole thing here, I am actually going to get rid of this and flip over here. I have a file already open called Townhouse Footprints, and you can find with the exercise files. And it's kind of the same exact layout that I was just working on, starting over here, you know with the 46 and the 16 and the 35. So you can kind of see, but I have added some little ins and outs for bay windows and over here there is a little hexagon bay.
And it continues down the entire facade, all the way to the end here. And there is an additional model line back here, which is where this townhouse portion of the project is going to abut up against the annex of the building. So we have one continuous model line running here and another one here. And again, everything's been dimensioned, so that later if the designer wants to go in and fine-tune the spacings of any of this line work, it's very easy to do by just coming in here tabbing in and selecting the line and making a modification.
And you can feel free to experiment with that if you like. But now because I deleted the line work out of the other file, what I'm going to do with this is, I'm actually going to load it into that other family. Now you could see it here it's just called Family15, it's just a--because I haven't saved it yet. That switches me over to the Family file, and as we've seen before we have got either place on face or place on work plane, so I need to switch to work plane in order to place it on the ground plane here. And what you see is that it's coming in at the original angle, it's not actually rotated to match our screen here.
So what we can do is, this'll give us an opportunity to use this Rotate after placement. So I am going to check that box, right there, click to place it in, and then type in an angle here of -79 degrees. And you'll see that that will rotate it around and orient it now to my box, it wants to place another one, so let's click the Modify tool to cancel out of there. And then I can go to--let's position it kind of roughly where it needs to go, just kind of by eye.
And then I'll go to Align tool, pick up a Reference Plane and kind of move around and you can see that I just have to sort of know where it is, but there's a Reference Plane right there, and I will align that and then I will do the same thing in this direction and I will align that. And that gets it positioned exactly where it needs to go. And if I zoom in just a touch you can sort of see how it matches up with this rectangle and so we are in pretty good shape. So, we are going to save this file off and then in the next movie we are going to start actually using-- I'm going to call them like blocks, what they basically are is they are almost like children's wooden blocks; is they are existing massing files that are already created and saved in standard forms like boxes and gables and triangles and so forth.
And I want to show you how we can actually take those forms and assemble them on this framework here and use this as a guideline to help us build up our townhouse facades. And so we will be looking at that in the next sequence, but by loading this in as a separate family, it allows us to snap to those points without it getting in the way. If we had left those individual lines as separate model lines, then when you try and select, it would think you're trying to create form directly out of those model lines.
So by burying it in a nested family we kind of moved it back one step and we can use it more easily as a guideline, as opposed to the actual geometry from which we are creating the form.
