REVIT PARAMETERS?

Question

How are parameters added to a Revit family to allow adjust-ability?

Answer 1

There are multiple parameter types for Revit families (ex. Dimension, Visibility, Materiality, etc).

For dimension parameters, you will want to pull a dimension string from an reference place, and label it with an easy to understand name (such as height, length, width, etc).

For Visibility and Materiality parameters, select on the object that you want to add a parameter to, navigate to your properties panel, and click the small gray rectangle to the far right of the "Visible" or "Material" box. This will bring up a list of parameters. Here you can apply a parameter that already exists or create a new one.

Be sure to test all your parameters to the minimum and maximum to assure everything works well.

I would also recommend exploring and understanding the difference between Instance and Type Parameters to fully maximise the family's capabilities.

Answer 2

When constructing a family in Revit, parameters are added by adding a dimension to a particular length that you want to be controlled. Note that this is done when the shape (extrusion, sweep, revolve, etc) is being created (pink lines displayed). Once the dimension is added, select it, right click>edit label>(enter your own title, such as "Length"),select instance parameter (in most cases), and categorize it. By adding a label to the dimension, the dimension becomes intelligent, in the sense that you can either change it manually, or it can be controlled by the result of other equations happening simultaneously within the Properties panel.
