Presentation
Well, here we are! The chapter you have probably been chomping at the bit to get into—and for good reason! It’s the output that we create from this chapter that will make our bosses, and better yet, our clients get behind our presentations Like I always say, none of this software is any good if you can’t capture the work to begin with That being said, in this chapter we will focus
on creating renderings and adding animations and provide solar studies based
on the project’s geographical location

creating an exterior Rendering
The first item we need to tackle is how to go about creating an exterior render-ing Just trying to address the subject of rendering as a whole would convolute the matter The thing is, when we create a rendering, lighting obviously plays a major role Day lighting and artificial lighting are two completely different bears; one will influence the effect of the other For example, if you are rendering an exterior scene, there are bound to be windows If this rendering appears at night,
or at dusk, the interior lights will be turned on
The objective of the first section of this chapter is to create a rendering from the exterior of the building using day lighting scenes, sky, and shadowing to create the rendering we need
In the previous chapter, we completed one of the hardest tasks when it comes
to creating a proper exterior rendering: how a building is rotated in terms of true north It stands to reason that your rendering will not be accurate if you have a glass curtain wall that is facing north but still have sunlight pouring through
it The correct building orientation is crucial, and we have accomplished that part If you didn’t read Chapter 18, “Site and Topography,” you can still proceed with this chapter, but I strongly recommend that you review the last section of Chapter 18 as soon as you get the chance
To get started, open the model you have been working on If you missed the
previous chapter, go to the book’s web page at www.sybex.com/go/revit2011ner
From there you can browse to Chapter 19 and find the file called NER-36.rvt The objective of the first procedure is to create a camera view that we can use for our first rendering We will then adjust the view controls and look at the sunlight effects
1 In the Project Browser, open the Level 1 floor plan.
2 Zoom in on the corridor area in the middle of the building.
3 Add some curtain walls to the corridors, as shown in Figure 19.1
(Come on, I know you can do it.) These are Level 1 to Level 3 with a –6″ offset from Level 3 You can use the Curtain Wall Storefront
4 On the View tab, select 3D View ➢ Camera
5 Create a camera view of the area shown in Figure 19.1.
6 Find the view in the Project Browser It will probably be 3D View 3
under 3D Views
7 When you find the view, rename it to Rendering View Corridor.

9 In the View Control bar, set Detail Level to Fine.
10 Change Visual Style to Realistic.
11 For the Shadows, select Graphic Display Options, as shown in
Figure 19.2

13 Turn on the Gradient background (at the bottom of the dialog).
14 Click the […] button to the right of the Sun Setting field (at the top of
the dialog in the Lighting area) This will bring up the Sun Settings dialog
15 Choose your geographic location for the settings Date, Time, and
Location (I am choosing Syracuse, NY, and my birthday [05/10 is the default].) You can change these settings if you would like (see Figure 19.3)
F i g u R e 1 9 3 The Sun Settings dialog
16 Click OK.
17 Click OK again to get back to the model.
18 Click the Show Render Dialog button on the View Control bar, as
shown in Figure 19.4
F i g u R e 1 9 4 The Show Render Dialog button
You can also access
the Graphic Display
Options dialog by
clicking the small
black arrow in the
right corner of the
Graphics panel.
Trang 6In the Rendering dialog, you will see quite a few choices Each choice will vary
depending on the scene you are trying to capture The following procedure will
move through the Rendering dialog from top to bottom
At the top of the Rendering dialog, you will see a button that says Render This
is actually the last button you will click This starts the rendering process in
motion For the rest, follow these steps:
N O T E the region toggle (the toggle to the right of the render
but-ton) allows you to pick a window to be rendered Since the scene in this
example is somewhat small, we won’t need to click this button If you were
rendering a much larger scene, you would render a region that way, it
won’t take hours upon hours to complete the rendering, and the resulting
rendered scene would be a smaller size
1 For Output Settings, set Resolution to Printer and to 300 dpi.
2 For the Lighting category, set Scheme to Sun And Artificial.
3 Set Sun to Sunlight From Top Right by clicking the […] button in
the Sun Settings row
4 For the Background category, set Style to Sky: Few Clouds (see
Figure 19.5)
5 Click the Rendering button After the scene is rendered, it should
appear similar to Figure 19.6
T I P Before you click the render button, find something else to do for
about two to three hours because at this resolution, revit needs about that
much time to render this scene I recommend that you have revit installed
on another machine at your place of business You do not want to watch the
rendering process as it is similar to gazing into a campfire plus, if your
model is being rendered on another machine, you can get some work done
So you waited half your day for this rendering to complete If you are like
me, you then carefully move your mouse around wondering how long it will be
before something happens and you lose your rendering

Trang 8The next procedure will look at how to save the rendering to the model, and
also how to export the rendering to an image:
1 In the Rendering dialog, click the Save To Project button, as shown in
Figure 19.7
F i g u R e 1 9 7 Saving the rendering to the project
2 Call the new rendering view Exterior Rendering at Corridor; then
click OK
3 Click the Export button.
4 Save the file somewhere where you can retrieve it You can choose
whatever file format you prefer
5 At the bottom of the Rendering dialog in the Display section, click
Show The Model The rendering now reverts back to the original
graphics style
6 Click the Show The Rendering button The rendering shows back up.
W A R N I N G the ability to jump back and forth from the model
to the rendering is a nice feature, but it is short-lived after you close this
view, the rendering is no longer available Do not close this view until you have
finished saving the view to the model and exporting it (if you wish to do so)
With our first rendering under our belts, it is time to create another exterior
rendering This time, however, we need to start adding some lighting and produce
this rendering at night There is nothing like a good before-and-after rendering to
sell a project
The objective of the next procedure is to add some exterior and interior lighting
to create a nighttime rendering scene
1 In the Project Browser, go to the Level 1 ceiling plan (that’s ceiling
plan in case you missed it).
2 In the Home tab on the Ribbon, click the Component button.
rendering may or may not come easy
to you It may take some trial and error
I know you are not made of money, but setting up a separate machine just for rendering is not a bad idea.

10 In the Properties dialog, choose the Sconce Light - Uplight 60W - 120V
family, as shown in Figure 19.9
11 Place seven lights on the walls of the northeast corner classroom, as
shown in Figure 19.9
Now that some lights are in place, it is time to look at how we can efficiently group the various types of lighting fixtures to create a nice lighting scene
Trang 10F i g u R e 1 9 9 Choosing the sconce
creating Lighting groups
All too often, we render scenes with no real consideration for the actual lighting
that has been added to the model Because we lean heavily on Revit to produce
accurate scenarios to present to our clients, we should spend some time thinking
through our lighting before we create a rendering
The objective of the next procedure is to create two lighting groups and to
render the same view using a nighttime setting
1 Select one of the sconces you just added to the model, as shown in
Figure 19.10
2 On the Options bar, click the Light Group menu, and select Edit/New
from the list, as shown in Figure 19.10
3 In the Artificial Lights - Level 1 dialog, click the New button in the
Group Options area, as shown in Figure 19.11
4 Call the new group Interior Lighting Northwest.
O remember, some components are more fickle than oth-ers Lighting fixtures sometimes take some finesse Make sure you are zoomed back enough to see a large portion of the wall, or revit may not place the fixture where you expected.
