Revit 2016 Global Parameters Jason Boehning Global parameters is like Project Environment meets Family Editor! This is a huge update in R2. There are really several situations in which you can use global parameters. First of all, global parameters allow you to drive the value of a dimension or constraint that is created in a project. Additionally, you can associate a global parameter to some element instance properties. In order for a global parameter to be assigned to an instance property, the global parameter must be reporting a value. Here are some simple examples to illustrate how global parameters can be used. On the Manage ribbon, in the Settings panel, click Global Parameters to open the Global Parameters dialog. In this dialog, you can see all the global parameters that have been created in the current project. There are options to edit existing global parameters, create new global parameters, and delete global parameters. Before you create a global parameter, think about a situation where one can be used. A simple example is where you want two dimensions to equal each other, but an equality constraint cannot be used. Sure, you can simply change the dimensions to equal each other, but what if they need to be updated? Or what if there are several that need to be the same, and you want to have some flexibility with change. In situations like this, you can create a global parameter and apply it to each dimension. When you click New Global Parameter in the Global Parameters dialog, Revit opens the Global Parameter Properties dialog. Here, you can specify a Name, choose the Discipline and Type of parameter, and add a Tooltip description, if needed. There is also an option to make the global www.cadlearning.com 15
