Autodesk Revit Architecture 2011 No Experience Required - part 38 pot

On the Modify | Grids tab, click the Copy button, as shown at the top and center of Figure 8.17.. On the Options bar, make sure the Multiple checkbox is selected, as shown near the top

5 When you pick the wall, the grid is added It will not be the name

or number you want We will change that But first, pick the round blue grip and drag the bubble up past the dimensions, as shown in Figure 8.15

6 Press Esc.

7 Select the new vertical grid.

8 Click in the bubble and rename it to A, as shown in Figure 8.16.

F i g u R e 8 1 5 Dragging the new bubble out of the wall

F i g u R e 8 1 6 The grid is now named A.

It is now time to duplicate this grid Since you have an arsenal of modify

com-mands under your belt, the best way to duplicate this grid is to copy it, as shown

in the following steps:

1 Select grid A.

2 On the Modify | Grids tab, click the Copy button, as shown at the top

and center of Figure 8.17

3 On the Options bar, make sure the Multiple checkbox is selected, as

shown near the top left of Figure 8.17

4 Pick a base point along the grid line within the wall, as shown in

Figure 8.17

5 Copy grid A to the wall centerlines, as shown in Figure 8.17 Notice

that the grid lines will autosequence as you go

F i g u R e 8 1 7 Copying the grid line to the other walls

6 Press Esc twice.

7 Start the Grid command again.

8 On the Draw panel, be sure the Line button is selected.

9 Pick a start point at the endpoint of the radial wall where it intersects

with the straight wall, as shown near the bottom of Figure 8.18

10 Pick the second point in line with the adjacent grid bubbles (see

Figure 8.18)

11 Press Esc.

12 Pick the grip on the bottom of the line, and drag it down past the

south part of the radial wall

The next step is to add the grid to the radial entry area This will not be as easy

as simply picking a wall’s centerline The trick here will be to establish a reference point to place the grid and, subsequently, a column

F i g u R e 8 1 8 Adding grid F

Adding a Radial grid Line

Sometimes, you have to think outside the box Literally Since we have radial geometry to contend with, we need to add a radial grid, as follows:

1 Zoom in on the radial entry of the east wing.

2 Click the Grid button on the Home tab.

3 On the Draw panel, select the Line button, as shown in Figure 8.19.

4 Type in an offset of 6″ on the Options bar

5 Pick the finished inside face of the radial wall, as shown in Figure 8.19.

6 The actual grid bubble lands in a congested area Fix this by adding

an elbow and adjusting the bubbles, as shown by grid G near the top

of Figure 8.20

I think you get the picture on adding grids The next procedure is to start

add-ing columns to these grid intersections To do so, we will explore the Structure

tab on the Ribbon

Adding structural columns

The hard part is over Determining where to put the columns is harder than physi-cally placing them in the model But of course there are rules to follow, and rules that need to be bent in order to accomplish the results we want to see

This next series of procedures will include adding structural components to the model and placing framing systems in areas where a structural engineer may defer

to the architect for structural integrity given their design intent

To begin, open the file you have been following along with If you did not

complete the previous section, go to the book’s web page at www.sybex.com/go/ revit2011ner From there you can browse to Chapter 8 and find the file called

NER-24.rvt

To add columns to the model, follow this procedure:

1 In the Project Browser, go to the Level 1 floor plan.

2 Zoom into the radial entry area in the east wing.

in Figure 8.21

F i g u R e 8 2 1 The Structural Column button on the Structure tab of

the Ribbon

4 You will probably not have any structural columns loaded into the model

If you get the message shown in Figure 8.22, click Yes to browse for a structural column

-Column.rfa

7 Double click on HSS-Hollow Structural Section-Column.rfa; you will

see a dialog allowing you to select the type, as shown in Figure 8.23

F i g u R e 8 2 2 You’ll see this message when no columns are loaded in the

model Click Yes.

F i g u R e 8 2 3 Select HSS-Hollow Structural Section-Column.rfa

and choose the HSS6×6×5/8 type.

9 Click OK.

10 On the Options bar, make sure Height is set to Roof, as shown in

Figure 8.24

11 Place the column on the grid intersection F-1.

12 Press Esc twice.

14 Place a column at grid intersection F-2 Before you place this column,

be sure Height is set to Roof

15 Place another column at grid intersection F-G (see Figure 8.25).

16 Select the column on the inside of the building (Column F-G) Once

the column is in place, press Esc twice to release the command

F i g u R e 8 2 4 Placing the column on grid intersection F-1

F i g u R e 8 2 5 Placing the two additional columns

17 In the Properties dialog, make sure that the top level is set to Up To:

Roof, as shown in Figure 8.26

F i g u R e 8 2 6 Setting the column’s Top Level to extend to the roof

N O T E Notice that Column Location is set to F-G this is important

because if the column is offset from one of these lines, revit will still

con-sider the column to be at that column location but with an offset dimension

18 Mirror the three columns to the opposite side of the entry using

col-umn line 3 as the reference plane

19 Save the model.

It’s time to start adding some full-height columns at the rest of the grid

loca-tions You will begin with the radial grid, and then place the rest of the columns

in the walls of the exterior and the corridor:

2 On the Options bar, be sure Height is set to Roof.

3 Hover your cursor over grid intersection G-2.1 Notice that you can

see the column, but it is at the wrong orientation

4 Press the Tab key on your keyboard, and the column will rotate to

align with the grid, as shown in Figure 8.27

5 When the column is aligned, pick the intersection The column is placed.

6 Repeat the steps for columns 3 and 3.9.

F i g u R e 8 2 7 Placing a column at an angle

It’s time now to start placing columns in the main part of the wing Place a column at every grid location Note that you must stretch the column lines to the left side of the wing You should also turn the grid bubbles on at the west and south sides of the building, as shown in Figure 8.28

F i g u R e 8 2 8 The grids should be extended and the bubbles turned on at each end.

Since you rotated

the first column,

notice that as you

follow the radius the

column rotates on

its own.



To add columns by intersection, follow these steps:

1 Start the Structural Column command.

2 On the Modify | Place Structural Column tab, click the At Grids

but-ton on the Multiple panel, as shown in Figure 8.29

F i g u R e 8 2 9 Using the “Place Column At Grids” function

3 Pick a window around the rectangular portion of the east wing (from

right to left), as shown in Figure 8.30

tab now changes to allow you to either finish or cancel Once you have

the window placed, click the Finish button on the Multiple panel, as

shown at the top of Figure 8.30

5 Press Esc.
