00:00:00,000 --> 00:00:00,620


2
00:00:00,630 --> 00:00:03,220
The bad thing about extruded roofs is the fact you

3
00:00:03,230 --> 00:00:06,270
can't follow along with the footprint of your building.

4
00:00:06,280 --> 00:00:09,110
The good thing is, we can do something about that.

5
00:00:09,120 --> 00:00:11,760
The objective of this video is to go to the Plan view.

6
00:00:11,770 --> 00:00:16,279
We will then create a void where our walls jag in and out.

7
00:00:16,290 --> 00:00:19,979
This is going to allow Revit to cut the roof properly in Plan.

8
00:00:19,990 --> 00:00:22,910
To get started, jump into your Revit Roofs file.

9
00:00:22,920 --> 00:00:28,709
In the Project Browser, let's go to the Roof level.

10
00:00:28,720 --> 00:00:34,200
To see all of our walls below, let's go ahead and select our Visual Style.

11
00:00:34,210 --> 00:00:36,390
Let's go to Wireframe.

12
00:00:36,400 --> 00:00:38,720
Now I want to start cutting some holes.

13
00:00:38,730 --> 00:00:44,460
On the Architecture tab, go ahead and click on the Vertical Opening button.

14
00:00:44,470 --> 00:00:46,470
Go ahead and select your roof.

15
00:00:46,480 --> 00:00:47,570
Now what I want to do,

16
00:00:47,580 --> 00:00:50,462
is I want to click on the Pick Lines button on the Draw panel.

17
00:00:50,472 --> 00:00:53,238
I want to give it an Offset of 2 feet.

18
00:00:53,248 --> 00:01:02,390
I am going to come in here and I want to offset this wall up, this wall over.

19
00:01:02,400 --> 00:01:04,660
This wall over.

20
00:01:04,670 --> 00:01:07,530
And then this wall over.

21
00:01:07,540 --> 00:01:08,410
On my Draw panel,

22
00:01:08,420 --> 00:01:12,559
I'm going to keep the Pick Lines button selected but my Offset is going to be 0.

23
00:01:12,570 --> 00:01:15,630
I'm going to click these two lines right here.

24
00:01:15,640 --> 00:01:17,009
I'm going to hit Escape.

25
00:01:17,020 --> 00:01:21,330
I'm going to type TR for trim.

26
00:01:21,340 --> 00:01:24,789
I want to click this line, and then this line.

27
00:01:24,800 --> 00:01:26,920
And then this line, and then this line.

28
00:01:26,930 --> 00:01:30,399
And I'm going to hit Escape.

29
00:01:30,410 --> 00:01:35,009
On the Draw panel, I'm going to use my Pick Lines button.

30
00:01:35,020 --> 00:01:38,360
I'm going to Offset 2 feet.

31
00:01:38,370 --> 00:01:39,247
I'm going to come in.

32
00:01:39,258 --> 00:01:40,499
Up.

33
00:01:40,509 --> 00:01:47,000
In again, set my Offset to 0.

34
00:01:47,010 --> 00:01:51,339
And I'm going to pick my roof edge.

35
00:01:51,350 --> 00:01:54,179
If you get a warning, that's okay.

36
00:01:54,190 --> 00:01:56,059
Hit Escape a couple times.

37
00:01:56,070 --> 00:01:57,990
Close out of the warning.

38
00:01:58,000 --> 00:02:00,020
Type TR.

39
00:02:00,030 --> 00:02:04,140
And trim them on up.

40
00:02:04,150 --> 00:02:07,710
I'm very lazy, so I'm going to go ahead and mirror these.

41
00:02:07,720 --> 00:02:09,820
I'm going to pick a window from the left to the right.

42
00:02:09,830 --> 00:02:13,360
I'm going to type DM for draw mirror.

43
00:02:13,370 --> 00:02:17,870
I'm going to pick the midpoint of my roof.

44
00:02:17,880 --> 00:02:19,570
I'm going to mirror that over.

45
00:02:19,580 --> 00:02:20,070
I'm going to hit Escape.

46
00:02:20,080 --> 00:02:25,960
I'm going to select these lines, I'm going to type DM for mirror.

47
00:02:25,970 --> 00:02:33,080
I'm going to pick the midpoint of this wall and mirror it over.

48
00:02:33,090 --> 00:02:33,670
I'm going to zoom in.

49
00:02:33,680 --> 00:02:37,750
And notice that I'm a little shy of this.

50
00:02:37,760 --> 00:02:40,900
These things happen in these situations.

51
00:02:40,910 --> 00:02:44,280
What we can do is, I'm just going to zoom out.

52
00:02:44,290 --> 00:02:49,390
I'm going to pick a window from the left to the right over those lines.

53
00:02:49,400 --> 00:02:53,170
On my keyboard, I'm going to hit my down arrow.

54
00:02:53,180 --> 00:02:57,600
It's okay if it goes out past it.

55
00:02:57,610 --> 00:03:03,860
Now that that's all set, I'm going to go ahead and click on Finish Edit Mode.

56
00:03:03,870 --> 00:03:05,070
I'm going to go to a 3D view.

57
00:03:05,080 --> 00:03:11,290
And see now that my ends are chopped out the way I like it.

58
00:03:11,300 --> 00:03:14,550
So by extruding a roof in elevation,

59
00:03:14,560 --> 00:03:17,920
we can also go to a Plan view to make our edits.

60
00:03:17,930 --> 00:03:19,450
So it think that does it.

61
00:03:19,460 --> 00:03:29,460
It looks good in X, Y and Z.
