Navisworks 2016 Database Link w/ MS Access - Primer
In a previous post, I discussed the process of connecting a external data source (Excel) with a Navisworks model. In this post, we will connect an MS Access database with a Navisworks model. As before, I’ll walk you thru how to setup the database link. For this demo, I am going to use the Gatehouse sample file that ships with Navisworks 2016. You can find the files C:\Program Files\Autodesk\Navisworks Manage 2014\Samples\Gatehouse\
The Process
In order to connect an Access database to a Navisworks model, we need to configure a DataTools within Navisworks. We will then be configuring the database connection. When working with the DataTools in Navisworks, there are a few very important rules to keep in mind. If you are using a 32-bit workstation, then you need to utilize the 32-bit ODBC drivers. 64-bit workstations need to utilize 64-bit ODBC drivers. It is also important to note, that the link to Navisworks is one way. Data can be linked and viewed inside of Navisworks, but the data can’t be updated within Navisworks.
My workstations are all Windows 10 64-bit workstations. My PC’s are using Microsoft Office 365. My Mac running Windows 10 64-bit on parallels using Office 365. The MS Access 2013 runtime drivers can be downloaded here: https://www.microsoft.com/en-us/download/confirmation.aspx?id=39358 If you are using an older version of office the MS Access 2010 drivers can be downloaded from here: https://www.microsoft.com/en-us/download/details.aspx?id=13255.
Data Source
The Gatehouse project includes a sample MS Access database which is why I am using it as an example
Our next step is to open Navisworks and the Navisworks model that you want to connect your external data source to. In Navisworks, on the Home tab, Project panel, click on the File Options button (Figure 2). This will open the File Options dialog.
In the File Options dialog, we will start the process of configure our database connection (Figure 3). As shown in Figure 1, click the DataTools tab and then click the New button to create a new DataTools link to open the New Link dialog.
In the New Link dialog (Figure 4), we first want to name the new link connection we are creating. For this example, I am using the name “Gate - MS Access Connection”. We then need to select the ODBC Driver Connection type. We are going to be working with a MS Access data source, so select the “Microsoft Access Driver” driver. Then click the Setup button to open the ODBC Microsoft Access Setup dialog.
In the ODBC Microsoft Access Setup dialog (Figure 5), we will select the MS Access data file and select the file we will be using. If you have the default installation of Navisworks 2016 and are using the Gatehouse example, you can find the file at: C:\Program Files\Autodesk\Navisworks Manage 2016\Samples\gatehouse\. After you have selected your MS Access file, click OK to close the ODBC Microsoft Access Setup dialog.
We are now back to the Edit Link dialog box (Figure 6). If we look in the connection section portion of the dialog, under the ODBC Driver selection, you can see that the connection has been updated. We can now complete the SQL String and Fields section of the dialog.
The SQL string is used to specify how the database will be queried. I have found this part of configuring the database connection to be the most difficult. Fortunately, there are a lot of external resources available for creating SQL strings. My personal recommendation is to keep it as simple as possible.
The code that we will be creating for this example is:
SELECT * FROM Gatehouse_Layerinfo WHERE "Name" = %prop("Item","Layer");
We start out our SQL String with SELECT * FROM The “*” is actually a field name, in this particular example, I am using the wildcard to query all the fields.
Gatehouse_Layerinfo This is the MS Access table name (Figure 7) that we want to query.
WHERE "Name" = %prop("Item","Layer"); This is where we are going to define what data we are going to bring from the MS Access tbale into Navisworks. For our example, we are going to conditional match the value Layer property data for each element that can be found in the Item tab and match that with a value in the Name column of the MS Access table.
“Name” refers to column that we will be searching.
%prop is a SQL command that allow you to retrieve model data for conditional matching.
("Item","Layer"); “Item” refers to the Item tab in the Properties Window. “Layer” refers to the internal file property, in this example, the Layer (Figure 8).
In the SQL String section of the Edit Link dialog, enter the following string of text.
SELECT * FROM [Gatehouse_Layerinfo$] WHERE "Name" = %prop("Item","Layer");
The next step in the process is to specify what information we are going to display in the Properties window. In the Field section of the Edit Link dialog (Figure 9), we are going to specify what Field names to list and the display name to use. Using Figure 9 as a reference, add the Field and Display Names.
Note that we are having the Field Name “Name” display as “Layer” in Navisworks. The Name column in our MS Access table refers to an AutoCAD Layer and rather than changing the column name in MS Access, we can have Navisworks use a different Display Name.
After you have entering the Field Names, click OK to close the Edit Link dialog box. Make sure that the “Gate - MS Access Connection” DataTools Link that we just created is checked. This will enable it in our current session. Click OK to close the File Options dialog.
When you select an object in Navisworks, note that the Properties Window has a new tab called “Gate - MS Access Connection”. That is the name of the DataTools link that we created. Figure 11 shows an example where we have selected the roof and in the Gatehouse tab in the Properties window provides us with the Layer, Finish and Note information from the Excel data file.
If you have gotten this far and it is not working, a lot can go wrong. The first thing to check is the SQL String text. Then check to make sure that your using the correct version of MS Access, which might be different than the selection, I made in Figure 5. Also, make sure that the MS Access file you are trying to access in Navisworks is not open. That can cause issues as well.
This Gatehouse example is not the most robust example around, but it is a great starting point. Start with something simple so you can make sure that your database connection is working, before trying it on a more complicated project with a lot of data to query. As many of you are aware, CAD and BIM applications are not great data entry applications, so having this type of data linking capabilities is very beneficial.

WHERE "Name" = %prop("Item","Layer"); This is where we are going to define what data we are going to bring from the MS Access tbale into Navisworks. For our example, we are going to conditional match the value Layer property data for each element that can be found in the Item tab and match that with a value in the Name column of the MS Access table.

SELECT * FROM [Gatehouse_Layerinfo$] WHERE "Name" = %prop("Item","Layer");
The next step in the process is to specify what information we are going to display in the Properties window. In the Field section of the Edit Link dialog (Figure 9), we are going to specify what Field names to list and the display name to use. Using Figure 9 as a reference, add the Field and Display Names.
Note that we are having the Field Name “Name” display as “Layer” in Navisworks. The Name column in our MS Access table refers to an AutoCAD Layer and rather than changing the column name in MS Access, we can have Navisworks use a different Display Name.

When you select an object in Navisworks, note that the Properties Window has a new tab called “Gate - MS Access Connection”. That is the name of the DataTools link that we created. Figure 11 shows an example where we have selected the roof and in the Gatehouse tab in the Properties window provides us with the Layer, Finish and Note information from the Excel data file.

ReplyDeletethanks for your explicit primer
i follow it and successfully link MDB to navisworks. when i was at "figure9" step, i wrote names with small letters in the "fields name" table so the new table in properties didn't create. so for other people who try this way i propose to be cautious about capital and small letters.
