In the Revit 2015 Project Environment, you can access the tools to Manage Selections from the Manage Ribbon:

However, this Ribbon Panel is not available on the default Manage Ribbon in the Family Environment  (Build 20141119_0715(x64) Update Release 5). What to do? Well, we can just add these tools to the QAT (Quick Access Toolbar), so then at least we can use them while building families. There are a couple of ways we can do this, but here is how you can do it while staying in the Family Editor:

  1. In the Family Environment, select more than one element
  2. Right-click on the Save Selection button that appears in the contextual ribbon (the green one) and “Add to Quick Access Toolbar”
  3. Save a Selection
  4. Select more than one thing
  5. Right-click on the Load Selection button that appears in the contextual ribbon (the green one) and “Add to Quick Access Toolbar”

You can also just add these items from the Project Environment, and as the QAT is shared with both environments, they will show when you edit a family.

However, while you can add the “Edit Selection” button to the QAT, it will not work in the Family Environment 🙁

The next generation of successful designers will have one important thing in common – the ability to quickly build the tool they need to accomplish a given task. Revit macro coding is one way to do this (Dynamo is another, even powerful Excel spreadsheets can qualify as BIM tools). But if you have had limited involvement with Revit macros in the past, you might be wondering “So… What is a macro anyway?”

One good place to start would in this great little article by Troy Gates on AUGI. Here are three tips from the article to get you interested:

  • I highly suggest creating the macros in the application tab so you can reuse the macros in any Revit model. If you store the macro inside the model, then it is only available to that Revit model.
  • The Revit API also allows the use of Microsoft LINQ (Language Integrated Query) functions. LINQ allows you to use a database-like query system to filter the elements contained in a collection. It is much more powerful and easier to use, in my opinion, when working with collections of Revit elements.
  • your code needs to define objects that the Revit API will use to interface with these. These objects are called UIDocument and Document…

Did you know that you can access Navisworks Options directly from the Start Menu? Just click on Start and type “Options Editor”. Then, if you hover over the entries in that list you can pick the Options Editor for the right version of Navisworks by reading the tooltip.

Why would we want to do this? Well, if you have a Graphics Driver problem, it might cause Navisworks to continually crash when you start the program. If you head into the Options Editor, you can go to Interface – Display – Drivers and disable various options until Navisworks decides to load up again.

For example, try unticking everything except OpenGL – you might find that Navisworks can now load (this tip may particularly help if you are trying to run Navisworks in a virtual machine).

Another stable choice may be to select only the software-mode drivers:

If you forget to close Revit before trying to install the Glue update, you might get this error. Just close Revit, remove the BIM360 addin and then reinstall it.
