Installation and configuration

Before you install Autodesk Revit 2020, close all applications.

Supported Operating Systems

Revit 2020 installations are blocked on systems running older versions of Windows 10 (Version 1507/Build 10240 and Version 1511/Build 10586) that do not support Microsoft .NET Framework 4.7. If you are running one of these versions of Windows 10, you'll need to upgrade to a newer version before installing Revit 2020.

Revit 2020 installations are blocked on systems running Windows 8 or 8.1.

Install or uninstall may fail if content is on a shared network location using a mapped drive

When installing or uninstalling, the procedure may fail if content had been redirected to a shared network location using a mapped drive. To prevent this error set the User Access Control in the Windows Control Panel to Never Notify.

Custom folder in deployments

In the Autodesk Revit 2020 Deployment Wizard, the Path for Configurable Folders allows you to specify a custom folder in which to copy content files. If you specify a folder location that has Read Only permission at the user level according to the Microsoft Windows User Access Control, then Autodesk Revit may become unstable. To avoid this, ensure that you have Write permission on your Microsoft Windows machine when creating your deployment with the Custom Folder option.

Roaming profiles in a networked environment

It is recommended that Autodesk Revit is installed from the same deployment when installing to multiple computers in a networked environment. This ensures each user's roaming profile is properly initialized when the user logs into different servers.

If a non-deployment install is utilized to configure multiple servers, each user's roaming profile settings are restored to the default values as the user logs into different servers. To resolve this, use these steps:

1. On the first server, locate the file Revit.ini in the folder: C:\ProgramData\Autodesk\RVT 2020\UserDataCache

2. Copy the InstallGUID value. For example: InstallGUID={AC00A40D-0386-400C-82DC-86818C5027F6}

3. On each of the other servers in the network, locate the Revit.ini file and replace the InstallGUID value with the value copied from the first server.

The first task you need to complete is to make sure that your computer meets the minimum system requirements. If your system does not meet these requirements, problems can occur, both within Autodesk Revit and at the operating system level.

Refer to the hardware and software requirements.

• In Autodesk Revit 2017 and previous releases, a UK Terminology option was available to enable the use of the British English in Revit. For Autodesk Revit 2020, this option was removed because British English is now a supported language in the Revit installer. Users that want to use the British English in Revit should select British English from the Installation Instructions drop down on the initial Revit installation page.
• In Autodesk Revit 2014 and previous releases, the program and content files were installed as part of a single installation package. For Autodesk Revit 2020, the installation of content files has been broken out into a separate installation package, Autodesk Revit Content Libraries 2020. Program related installation settings, including desktop shortcut, discipline, and project path, remain part of the original Autodesk Revit 2020 installation package while content related installation settings, including content packs, default content, and configurable folders, are now associated with the Autodesk Revit Content Libraries 2020 installation package.
• The Autodesk Revit Content Libraries repair process will not restore missing content files. If you need to restore missing content files, running the Autodesk Revit Content Libraries reinstall process will accomplish this goal.
• If the default content setting is modified through the Revit Content Libraries add or remove features process, the UserDataCache and user profile copies of the Revit.ini file are not updated to reflect this change. Running the Autodesk Revit repair process ensures that both copies of the Revit.ini file are updated to reflect the new default content selection.
• Refer to the online Autodesk Revit 2020 Release Notes document for details on the customer incidents resolved within this release.

Measure Tools

The measuring tools in Navisworks have some simple commands that make them very powerful. But first we’ll look at the measure window and how to read it.

Figure 1: Measure window

The measure window consists of four rows: Start, End, Difference, and Distance. At the very top are all the measure tools: Point to Point, Point to Multiple Points, Point Line, Accumulate, Angle, Area, Shortest Distance, Clear, Transform Objects, and Convert to Redline. These same tools can be found under the Review tab.

The measuring tool is pretty straightforward, but there are a few things you should understand before measuring. The Start and End rows have three columns. These columns represent from left to right the X,Y,Z coordinates of your measurements based on where your 0,0,0 point is in the project. Navisworks gives you the option to lock your measuring direction to the X,Y,Z axis and parallel or perpendicular to a surface. This is important to remember because if you want to pull certain measurements from your Navisworks model, you need to pay attention to how you export your models or how you position them in Navisworks.

For example, if I want to get the flat dimension between two pipes running straight but at different elevations, I could use the Point to Point measuring tool. After selecting a point on my first pipe I can hit X or Y on my keyboard and Navisworks will lock the measurement to that axis. But what if my Autodesk® Revit® model was rotated 15 degrees and I exported using Shared Coordinates? The X,Y axis in Navisworks would be off, so if I tried this measurement with a rotated model it wouldn’t work. I would either need to zero out my rotation in Navisworks by selecting the entire model and opening its Units and Transform, or I could change the exported setting in Revit to export using Project Internal coordinates.

Another way I could get that measurement if my model was not rotated is by using the shortest distance tool. After selecting the two pipes I can hit the Shortest Distance measurement and Navisworks will (frustratingly) change my view and then pull that measurement. The measurement will be at an angle which is not what we were looking for, but if you look in the Measure window in the Difference row you can see the flat measurement along the X axis. The measurement can be very different from the shortest distance measurement as shown in Figure 2

Speed Sectioning

Sectioning can be a very useful tool during coordination. Sometimes you will have the luxury of sectioning before a meeting and preparing views, and other times you will need to section on the fly while everyone is waiting. There are quite a few tools for sectioning, but I will only cover the ones I have found most applicable to BIM coordinations. When preparing views before a meeting, Saved Viewpoints are great because they will keep your section cuts, redlines, and hide properties so you can set up views that will clearly display an issue. During a meeting I recommend having the Section Plane Settings window open even when sectioning is turned off.

Figure 3: The sectioning planes window can be turned on under View/Windows/ Sectioning Plane Settings

Sectioning on the fly can be fast and easy. You can try to use the Top, Bottom, Front, Back, Left, or Right standard sections and then move them to the desired location. At times it is also helpful and faster to use the Align to View cut, but your camera is often not straight so your cut will be at an angle. The cut I use most often is the Align to Surface cut. You may have noticed that throughout your Navisworks models there is no shortage of flat surfaces in every view. Whether it be a wall, ceiling, beam, duct, or even hanger, there are plenty of flat surfaces you can use to section quickly with the Align to Surface cut. Within two or three mouse clicks you can have a perfect section cut; when you select Align to Surface your cursor will turn into a crosshair. Use your crosshair to select a flat surface close to where you would like your final cut. Once you select your surface and your section cut is turned on with the check box next to it, you can adjust the cut with the Move command and you’re done. You can add two or more section cuts just as quickly until your scene shows what you need it to show. And if you clicked on the wrong surface or want to pick a different surface, just use the green Re-select button to the right of your cut.

I recommend saving a viewpoint after making important section cuts that you might want to see later.

BIM 360 Glue

As I mentioned earlier, many of the measuring capabilities we have in Navisworks Manage are also in Freedom and BIM 360 Glue. Because this information can be so important we want our project team to have access to it. We have found that the easiest way to empower them to use the models is through BIM 360 Glue. Training anyone on Glue takes less than half an hour, and they will be able to navigate a model, view redlined saved viewpoints, and pull their own dimensions. The Point to Point measuring tool in Glue has a feature that I think Autodesk should consider putting into Navisworks—that is when you take a point-to-point measurement it automatically shows you the X,Y,Z measurements in different colors.

These simple tools can be easily learned and taught to the project team, freeing you up for more technically intensive tasks.
