In the opening Module of this course we talked a little about how Revit uses parameters for everything it creates. In this Unit we going to revisit that topic and look at parameters in more detail. Parameters really are at the heart of Revit, so it’s certainly worth reiterating the principles.
- Everything is driven by parameters
- One model, one database
- Change it once and it changes everywhere!
- You decide where to change it
Everything is driven by parameters
All elements within Revit are controlled using parameters and associated values. Let’s take a pair of external double doors (see image above) as an example. If we select the doors (selected elements are always highlighted in blue by default) we can see its parameters and associated values displayed in the properties palette (see below).
The parameter names are shown on the left hand side of the Properties Palette (highlighted within the red box in the image above) whilst their associated values are displayed on the right hand side of the Palette (highlighted within the green box). Four example we have a parameter called Frame Material and its associated value is Metal. We can click on the values (the ones within the green box) and change them directly within the Properties Palette. In addition to those listed by default, we can create custom parameters to our elements, to store a variety of different information.
Once model, one database
One of the key features of Revit is that there are many places which we can choose to change our information- those changes always going back to central database. For example in the image above, I have selected a section of external wall. I can see all the properties of that section of wall in the properties palette (number 4 in the above image). I could also change the wall’s height or location in any of the three views open in the drawing area. If I change the wall’s height in any of those views, the change would be instantly reflected in the other views and also the height value in the properties palette would be updated accordingly. Conversely, I can simply type a new value for the wall’s height into the properties palette and the height of the wall would change accordingly in the three open views.
Change it once and it changes everywhere
You decide where to change it
- All elements in Revit are controlled by parameters which have a name and an associated value.
- No matter where you make your changes to an element or asset, that change will permeate back to the database and update all other associated views that show the relevant element.
- As the views of your model are generated from a single database, coordination issues in Revit are almost non-existent.
