This week we learn the basics of Navisworks and creating a simple federated model.

Task 1: Getting familiar with Navisworks 1. Open a new Navisworks file and explore the interface with the aid of the following resources: Useful websites •

2. Activate the Navisworks Standard Workspace. While this is not mandatory to work with Navisworks, you will see that the most frequently used tools (such as Clash Detection, Timeliner, Sets, Selection Tree and etc.) are readily available around the perimeter of your workspace when you activate this workspace. This will save time.

3. Go to Global Options from the application button and change the settings as below:

a. Auto-save i. Set the ‘auto-save’ directory as your student drive ii. Set the ‘auto-save’ frequency as an hour iii. Set the maximum number of previous versions as 04

b.

From the ‘Interface’ tab: i. Set the linear and angular units into millimetres (set the number of decimal places accordingly) and degrees, respectively.

ii. Go to ‘Viewpoint defaults’ and make sure that the first two checkboxes are ticked as below.

Similar to creating different views in the Revit using the project browser, we create viewpoints to communicate in Navisworks. To see certain types of elements in a particular view, sometimes, we hide other elements. Also, we colour code elements based on certain properties of elements (for example, fire ratings of doors) for communication purpose. To do so, these two boxes need to be ticked.

4. Ensure that the following dockable windows are open and placed around your workspace. This is not also a mandatory step but will assist you to work faster. i. Saved viewpoints ii. Properties iii. Sets iv. Selection tree

Task 2: Creating the Federated Model The design of a project is done by multiple firms. At certain points, they need to be integrated to create a federated model. The advantages of creating a federated model are: •

Assist design co-ordination and approval

•

Assist clash avoidance and clash detection (we will learn this next week).

•

4D simulation (we will learn in BLDG3016 and a bit in BLDG2015 too_

•

Estimating

Required Reading At this point, you are required to read the following wiki entitled Federated building information model. •

https://www.designingbuildings.co.uk/wiki/Home Type the article title into the search box.

1. Download the zip folder entitled “Module 6.zip” and extract it. You will see the following three files. Now, we are going to use them to create a simple federated model.

2. Use the file that you have applied settings as described in Task 1. We will use ‘Append’ to create the federated model. a. First, bring the architectural model using ‘Append’

b. Note that the model is shown in the selection tree now. Expand and note the hierarchical structure of the selection tree. Selection tree is useful to select particular types of elements from the model.

c. Measure the dimension of any door to check whether the unit transformation is correctly occurred while appending.

d. Upon confirmation, append the structural model. Ensure that unit transformation is correct. e. Note the changes in the selection tree after appending the structural model. f.

Similarly, append the MEP model.

Task 3: Viewpoints Similar to Project Browser in Revit, we use ‘Viewpoints’ in Navisworks to establish different views. They are created in the ‘Viewpoint’ window.

Establish the following viewpoints for the federated model created above: 1. Home view to show all the elements 2. Arch_Home to show only architectural elements 3. MEP_Home to show only MEP elements 4. Struct_Home to show only structural elements 5. Structural_Frame to include only a. Structural columns b. Structural framing c. Structural foundations Using viewpoints, the project team could review the model. This will be described in another week.

Task 4: Creating Sets In the remaining few weeks of this course, you will use sets excessively. Therefore, the basic skills should be developed during this week so that you will be able to carry out the next exercises well. A set is a collection of elements that you save for future use. Sets are saved in the ‘Set’ window:

There are two types of sets as described below:

Search sets – Use ‘find items’ and apply search

Selection sets – use the 3D model or selection

criteria to find elements; then, the selected

tree to select the elements of interest. Then,

elements are saved using ‘save search’

the selection is saved using ‘save selection’

1. Select all the doors from Selection Tree and save the selection as a set (think of the appropriate set type before saving) 2. Find an M_Single-Flush 0915x2134mm door from the 3D model. Then, use ‘Select Same’ from the Home tab to find all the doors belonging to this type. Upon selection, save them as a set using the appropriate type.

3. Use find items to create the three sets given below: a. Pipes that the name contains ‘flex ducts’= element/category/… b. Any structural element that the grade is 345 MPa element/ structural material c. All interior walls /Item type

Task 5: File Types Navisworks has three native data formats, which are: •

NWC;

•

NWF; and

•

NWD

Useful websites These file types are explained further in this Autodesk Forum: •

https://knowledge.autodesk.com/searchresult/caas/sfdcarticles/sfdcarticles/Difference-between-NWDand-NWF-file-formats.html.

Now we are going to save your federated model. When we use ‘save’ or ‘save as’ to save the federated model, the default given date format is NWF.

1. Save the project as an NWF file. 2. Go to the location you saved the file and check for the file size: you will see that it is a very small file with compared to the original files amended.

So the questions is how the federated model becomes much smaller than the individual models you amended. This is because the NWF file does not save the geometry. But you can still see the models until you have access to the original files. This is a smarter way to work with large files. However repeating here, the mandatory condition is that you will need to have access to the original model. Thus, when you send a Navisworks model to an external party (assuming that they have no access to the original models), the NWF file format is not suitable. At such occasions, you will need to convert an NWF into an NWD. To convert, there are 03 methods: 1. Use save as a. Using save as, save the model as an NWD file (select *.nwd as the save as type).

2. Use publish

a. Using publish, create the NWD file. Make sure that the model is password protected and an expiry date is assigned. Discuss why assigning an expiry date is important. 3. Use batch utility (Will explore in Module 8)

Exercise

Exercise Using the federated model created above, audit the internal walls for their fire ratings. Assume that this project has a specification to be satisfied that ‘all internal walls must be of 02 hour fire resistant’ [note that FRL is given with 03 designations in Australia, such as 120/90/120 (see residential construction notes for more information). For this exercise, ignore this requisite and note that the fire ratings are fed in the model only as 1 HR, 2 HR, etc.]. You will need to do this exercise using the ‘find items’ tool....
