creating a solar study
A solar study, put simply, is a shaded 3D view that provides a time-elapsed visual image of how the building will cast shadows over the course of either a day or multiple days
The objective of this procedure is to create a single-day solar study by specify-ing the geographical location of your buildspecify-ing:
1 Go to the view {3D} in the Project Browser.
2 Right-click and choose Duplicate View ➢ Duplicate With Detailing
3 Rename the new 3D view to One Day Solar Study.
4 On the View Control toolbar, click the Sun Path button, and choose
Sun Settings
5 In the Sun Settings dialog, click the Single Day radio button, as shown
in Figure 19.23
6 Click the Duplicate button.
7 Call the new configuration Single day Syracuse, NY.
8 Make sure Place is set to Syracuse, NY (or wherever you find yourself
these days)
9 Change Date to 05/10/2009.
10 Set Time Interval to One Hour (see Figure 19.23).

N O T E Unfortunately, you need to have a high-performance machine
to perform this study If you do not, this one-day solar study could take one
full day to complete It will be in real time
Creating animations such as solar studies and walkthroughs are a couple of
the unique features of Revit that aid you in capturing work Keep these features
in mind next time you are working up a proposal and a presentation

Revit Models
It is amazing that we are up to Chapter 20, and I’m sure many readers are still unclear about how BIM fits in here Yes, most of the previous chapters showed you how you benefit from BIM when you change an item in one place, and it changes in another, yada, yada, yada But you were probably sold on the whole “coordinating with your consultants” thing back when you were con-sidering purchasing Revit Well, here we are It’s time to tackle that mystical ideology that has put our industry in a loose headlock

Linking a Revit structure Model
The first section of this chapter will focus on the actual event of importing a Revit Structure model As you start the process, you will see that this procedure
is not unfamiliar if you have any CAD background whatsoever If you do not have
a CAD background, I think you will find these procedures to be intuitive enough
to get through importing Revit models with no experience
As you proceed into design development, you must get your structural engineer
on board This consultant may be an external or an in-house resource Either way, this individual will have a different model that you need to coordinate with This section will focus on the procedures involved with importing a Revit Structure model We will also cover the concept of creating a live monitoring system with the structure as well as interference detection
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
file in a location where you can retrieve it
The objective of the following procedure is to import and link a Revit Structure model
1 In the Project Browser, go to the Level 1 floor plan.
2 Delete every structural grid and column (Keep the canopy framing
intact Do not delete the beams and columns in these two areas.)
N O T E Why are you deleting these structural members you worked so hard to add? Because the structural consultant laid out their grid based on yours You are going to copy their grid back in, and monitor any movement that may occur throughout the life of the project as far as the columns, we are simply going to use the structural engineer’s columns for our elevations, plans, and sections from this point on
3 On the Link panel of the Insert tab, click the Link Revit button, as
shown in Figure 20.1
4 Browse to the NER-37_STRUCTURAL.rvt file, but do not click Open just yet
5 Select the file.
6 At the bottom of the dialog, you will get a choice of positioning
Select Auto - Origin To Origin, as shown in Figure 20.2

7 Click Open Your structural model is now linked.
8 Open the 3D view East Entry From Corridor.
F i g u R e 2 0 1 The Link Revit button on the Link panel of the Insert tab
F i g u R e 2 0 2 Pay attention to the choices provided before you click Open.
You can now see the wood framing the structural engineer added to support
the cantilevered slab, as shown in Figure 20.3
Already we are seeing the benefits of a collaborative model, and we have done
nothing more than insert one model into another This is not new technology,
and we are certainly not doing anything profound here The real benefit comes
from how we can now keep track of what the structural model is doing
under-neath our model We can actually copy items from the structural model, and then
monitor any changes made from the linked model This is the definition of BIM

Activating copy Monitor
You can almost sum BIM up in one command: Copy Monitor I hate to break down the most import acronym in our industry since CAD into such simple terms, but building information modeling is the process of monitoring and tracking change, and that process starts right here!
The objective of the following procedure is to copy the structural grids and apply
a monitoring system that will alert you when the grids have moved Although this book will focus solely on copying and monitoring the grids, your takeaway will be the experience required to recognize the procedure and the importance of this function
To create a copying and monitoring system, follow this procedure:
1 Go to the Level 1 floor plan.
2 On the Coordinate panel of the Collaborate tab, click the Copy/Monitor
button On the fly-out, click Select Link, as shown in Figure 20.4
3 Hover your pointer over one of the grids You will see an outline of the
Revit Structure model that you have linked in When you see the out-line, pick the grid (see Figure 20.5)

Figure 20.6
5 On the Options bar, check the Multiple option.
6 While pressing the Ctrl key, select all of the grids in the linked model.
7 When you are finished, click Finish on the Options bar, as shown in
Figure 20.7

F i g u R e 2 0 6 Clicking the Copy button
8 You will get a warning saying that “The following types already exist but
are different.” Just click OK Your grids should look like Figure 20.8
9 Close out of any warnings stating that new items have been renamed
This is inconsequential information
F i g u R e 2 0 7 The Finish button on the Options bar
It is often
over-looked, but you must
click Finish on the
Options bar or the
copying and
moni-toring process will
not take effect.
Now that the grids are being monitored, it is time to take a look at what we can copy and monitor from our consultant’s models by configuring the Copy/ Monitor settings
Adjusting the copy/Monitor options
By copying the grids into the architectural model, we are actually proceeding with the most common, and by far the safest, function of this command If you
do choose to copy and monitor items such as foundations and columns, you can automatically replace the items being copied with an alternate component For
example to emphasize something you would not want to do Be careful while replacing components you are getting from the structural model
The objective of the next procedure is to look at the Copy/Monitor settings
1 On the Copy/Monitor tab, click the Options button on the Tools
panel, as shown in Figure 20.9

2 Notice that Revit will replace any column indiscriminately with a
replace the entry with Copy Original Type (see Figure 20.10).
3 Change the rest of the columns to Copy Original Type and click OK.
4 On the Copy/Monitor panel of the Copy/Monitor tab, click Finish, as
shown in Figure 20.11
5 Save the model.
