Entering the Rvit Architecture program, the page will look like the one above. Click on the R in the

upper left had corner and go to New then Project. A message box will come up, click on Browse,then select the Construction template and click Open.


3/66

Setting Building Elevations

There are two important elements to establish first, before continuing a new

Revit file, the horizontal limits and the vertical limits. Vertical refers to the z

coordinate, heights in the building that this tutorials refers to as Elevations. Inthe Revit program it is called a Level. Horizontal Is the x and y coordinates. This is

the 2D view where the Structural Grid will be laid out. Start first with the z

coordinate, Elevations or Level.


4/66

Go to Building Elevations and then East. Double click on the East Elevation in the Project Browser. Thetemplate chosen at the beginning has already preloaded elevations. However, these will have to change toreflect the correct elevations for this project. The next slides gives an explanation how to create and modifythem to suit the project.

Establishing Elevations


5/66

The Level icon and the Grid icon are both in the Home menu. As the project sets up these icons will be used.However, much of the set up for Elevations can be achieved by altering the data within the Elevations.


6/66

By hovering over the Level icon, the tab can be seen. To create new Levels, click on the Level icon.Or, as will mostly be the case here, the existing Elevations can be altered.


7/66


8/66

Notice that currently there are seven (7) levels identified. The project will require ten (10) different levels. To

begin, double click on any level name and then change it to something that will be needed for the project.Always answer yes to the box that asks if you would like to rename corresponding views.


9/66

By clicking on each Level line, they can be dragged . The software locks them together (see the paddle lock

symbol). This means that when you move one level then all that are locked together will move too. To insertadditional levels, click on the Level icon, click and drag the new level until it lines up with the others.


10/66

When you have finished revising

and adding levels, they all should

look like this.

By clicking the little squigglyline you can adjust the levels

in order to avoid level overlay.

Align both ends of the levels

to match the existing


11/66

Structural Grid


12/66

Back to the Home tab. Double click on the Main Level (Level 1, the same thing) on the Project

Browser. Select the Grid button.

Placing Grid Lines


13/66

From Level 1, start at the bottom and randomly place 6 vertical grid lines.


14/66

Then from right to left, set 4 additional horizontal grid lines. Please notice the placing of thebubbles, they are to the left and top.


15/66

Starting with the top, double click on the horizontal grid bubbles. This should allow you to change the

numbers to letters. Change the names of each using letters starting from A at the top to D at the bottom.


16/66

Go to the Modify tab and then Aligned Dimensions. Click on that icon.


17/66

ALTERING STRUCTURAL GRID LINES In Aligned Dimension, click and highlight grid line #1, and

then click highlighting grid line #2. This sequence is to dimension the grid. Place the dimension line

near the top grid bubbles and click.


18/66

Continue the process until you have a string of dimensions across the entire horizontal structural

grid. Dimension the horizontal grid lines similarly. Revit will snap the dimensions to match the firstdimension placed. Place all dimensions in one line.


19/66

At this point we are going to modify the grid lines to reflect the correct dimensions. In the Modify tab, selectthe Modify icon. Click on grid line #2 to identify it, the rule is that you always identify the element you desireto change first. Now identify the dimension line between grid lines 1 & 2 and double click on the dimension

itself. This will allow you to change it to what it is supposed to be. Horizontal dimensions from grid line 1 -6are 15-0, 19-6, 16-3, 19-6 and 15-0. The vertical dimensions from A D are 15-0, 35-0 and 15-0.


20/66

Repeat this process, identifying the grid line to move and changing the dimension appropriatelysequentially until all of the dimensions are correct.


21/66

When complete with the correct dimensions between all grid lines, the Structural Grid shouldresemble the one in this slide.


22/66

Structural Columns


23/66

Go to the TO Footings level. Select the Structures tab. Select Columns and then

Architectural Columns.

Note: make sure that the

Properties Browser is set to

the correct Base and Top

Levels with no offsets

before you place columns.


24/66

From the Properties Browser, click on the column options to observe what are loaded columns.

Select the 24x24 Concrete Column. You now have the column loaded and ready to place.


25/66

Snap just one column into place at gridline 1-B.


26/66

Lets say that the 24x24 column is not exactly correct and we need a 20x20 column. Identify the placed column by clicking on it. Go to Edit Type Properties

and click duplicate. A box appears asking for the new name, rename the column to 20x20 column and then change its properties dimensions to be20x20. Verify that the Base Level is at TO Footings and the Top Level is set at Roof Level and that both top and bottom offsets are set at 0.


27/66

The column that was inserted will now be a 20x20 column and loaded prime for placement. Begin placing the newly created

20x20 concrete column to the indicated gridline intersections. The column will snap to gridline intersections. Insert all of theconcrete columns at this time.


28/66

There are 4 interior columns but they are structural steel. So go to Structures Column - but this

time select the Structural Column.


29/66

Select Edit Type Properties, click on the Family tab. Verify that the W-Wide Flange Columns are loaded.

Then select the Type tab. Assuming that the project calls for a W12x40 column. If that column is not listed inthe Type tab, then it will need to be loaded. If so, click on the Load tab. This window will appear.


30/66

From the new window, go to Structural, then to Columns and then to Steel Wide Flange at the

bottom. Scroll down to the W12x40, select it and press OK.


31/66

There are no limitations definable for this column, so we will probably need to alter the base and top constraints. Place this column at

the denoted 4 grid locations. Now select one of the columns, Right Click, Select all Instances and Visible in View. Set the PropertiesBrowser column, the base constraint TO Footings and the top constraint to Roof.


32/66

By clicking the 3D icon your model should reflect something like this. If any columns do not meet the property criteria, select any out-

of-line columns and change their constraint properties.


33/66

Foundation Walls


34/66

For this section begin by going to the TO Footings level. Then go to the Structure tab and select Wall then Structural Wall.

Placing Foundation Walls


35/66

Click on the Properties Browser and select from the pull-down menu the Foundation 12 Concrete.


36/66

This is where the foundation walls are inserted. Set the Location Line at Finish Face Interior, the Base Constraintat TO Footings and its offset at 0, the Top Constraint at Unconnectedand its offset at 16-0.


37/66

By selecting Finish Face Interior then the direction on wall placement should go in 1 specific direction. Startplacing the walls, moving in a clockwise direction from outside corner of column to outside corner ofcolumn.


38/66

The completed foundation wall with the columns should look like this.


39/66

For placement of the building footings, go to the Structure tab, select Wall foundation.


40/66

From the Properties Browser, click for the pull down menu. Then select the Bearing Footing36x12. The Properties has only 2 footings loaded, neither areacceptable for this project. Therefore, a change will be made. Click on Edit Type and the Type Properties window appears. To ensure that the footing which was

selected does not change, select Duplicate and rename the new footing 24x18 Cont. Footing. Then change the Width and Thickness values to reflect the 24x18footing and click OK.


41/66

The next part is very easy as the system knows exactly where the foundation was are located. By hovering over a foundation wall, seeing it highlight and clicking

on that wall, the system will put the footing correctly under the foundation wall. Do not concern yourself if you get a warning window because in this view, theview range does not see the footings, but they are there. Proceed to highlight all foundation walls and insert a footing under each.


42/66

Next are the column footings. From the

Structure tab, select Isolated Foundation.


43/66

The footing that is desired may not be loaded, soStill in the Structures tab, click Edit Type and in the

pull-up window, click Duplicate. Change the name of the footing to be 48x48x18 spot footing andchange the dimensional properties to Width = 4-0, Length = 4-0 and Thickness = 1-6


44/66

Place the new footing by snapping it to the structural grid intersections. Place this footing at all columns. You may get a warning window, but

this typically is referencing that the footing cant be seen in the current view. Go to the 3D view to view the footings.


45/66

Having selected all foundation walls and placing all spot footings, your 3D model should look like this

view. This is an underside view of the building.


46/66

Basement Floor Slab


47/66

Go to the basement level and select Structures then Slab Foundation Slab.

Placing Floor Slabs


48/66

The floor may already be loaded, look in the Properties Browser pull-down menu to verify. If not, go

to Edit Type Duplicate and change the name of this default slab to a 6 concrete slab.


49/66

You are now in the Create Floor mode. Click on each foundation wall to identify the perimeter, creating the slab boundaries, be

sure to keep the boundaries inside the walls. Make sure that none of the boundary lines overlap and/or do not cross. Afteridentifying all walls creating a closed loop, click the green check mark. to finish the floor system.


50/66

By this point, the 3D view should look like this.


51/66

Suspended Floor & Roof Systems


52/66

Go to the Main Level floor plan. Then go to Structure tab then select Beams W-Wide Flange.

Placing Floor Systems


53/66

First, go to the Structure menu and select Beam, the family should load. Click on Edit Type, pick the W-Wide Flange Family then

Load. Then go to Structuraland Framing W-Wide Flange. Select from the window the appropriate beam to be used accordingto the project. There are two different sizes, perimeter beams are W30x99 and interior purlins are .


54/66

From Level 1 begin placing the beams. Place the W30x99 beams from face of column to face of column in the Main Level around the

perimeter of the structural framework, notice the offsets of the beam. Be sure that the offsets are set accurately before you begin.


55/66


56/66

From the Main Level go to Structure Beam System. Rarely will the Automatic Beam System work

properly, so select Sketch Beam System. Set the fixed distance to 4-0.


57/66

From center of column to center of column sketch the boundaries of the framing area. Each individual framing will beidentified until all framing areas are complete. Do one area at a time. The parallel lines represent the direction of the joists,

to change the direction click the Beam Direction tab. When finished defining the framing area, click the green arrow.


58/66

Notice that the framing has been populated by W12x50 beams. Since the beam system rarely recognizes the Bar Joists planned for the framing, some altering of

properties will be done. Select one of the W12x50 beam trusses, right click and select all instances in the project. Then click on Edit Type, go down to Structuraland click, then select Framing and then Steel. The steelwindow comes up, select the K Series Bar Joists and then the 18K9 joist. Then click all of the Oks.


59/66

This action will change all of the W12x50 beams to the K Series truss that was selected. This will

complete the floor framing structure for the Main Level.


60/66

ROOF STRUCTURE Next the roof structure and system will be installed. Go to the Level 1 and clickto identify one of the bar joists. Right click and go to Identify all Instances. Up in the red box click

the Copy to Clipboard icon.


61/66

The roof structure in this building is the same as the floor structure. Go to the Roof Level click on the Paste icon and Aligned to

Current View and click. Then go to the TOS 2 level and click on the Paste icon, then down to Align to Current View and click. This

might take a little time, but when the system is finished you should have copied all of the K Series joists to the top of steel at the roof.

Please note: that this process

must be completed for all of

structure including beams.


62/66

With the roof structure in place, there is a slight modification that needs to be accomplished. By copying the Level 1 structure to the

roof, it has a hole in it for the stairs. Go to the TOS 2 level and zoom in to the stairway area. Select the last bar joist and then click on

the Copyicon. From endpoint to endpoint copy the joist 4-0 to the right. Repeat the process one more time and it is finished.


63/66

To put in the Level 1 floor and/or Roof Level concrete slabs, follow this: From the Level 1 click on the Structure FloorStructural Floor icon sequence.Select Edit Type and be sure that the roof slab is set for the 3 light weight concrete on 2 metal deck. Thus option has a total thickness of 5, therequirement is a 6 roof deck. So, click on the Duplicate button then rename the slab to 4 light weight concrete on 2 metal deck and click OK. Nowclick on the Edit button. Notice that the structural composition of this slab as not at all what is called out for. In this new window, change the

composition to reflect the one shown then click all of the Oks to end the process. Identifying the boundaries for creating a new slab involves hoveringover and clicking on the exterior walls, this being the perimeter of the building.


64/66

Both slabs will be the same, so you could copy and paste the one just made to the correct level. Remember though, if you do this the slabs do not have thesame perimeters (Level 1 stair well), then you would need to Edit Boundary for one or the other. The second option would be to repeat the sameprocess for the next level. The process involves going to the Structure menu then click on Structural Floor and select the new slab that was just created.For the Level 1 slab, consideration must be taken for the stair well. If you copied the slab from another level, then you will need to Edit Boundaries after

clicking the green checkmark to finish the process. Boundary properties were copied with that slab. Modify the boundaries to accommodate the stairwell.Creating a new slab involves hovering over and clicking on the exterior walls, this being the perimeter of the building.
