When you make a new Revit parameter you choose the Type of Parameter, and that determines the type of data that the parameter can hold:

A PropertyWizard formula usually affects all the elements in the category you’ve selected. But what if you only want to affect a subset of the elements? You can do this with an if() function in this form: if(<filter criteria>, <your formula>, <target parameter>) The <filter criteria> is where you choose which elements to affect, and

PropertyWizard’s if() function works in the same way as the native Revit one, which is described in the online Help here: http://help.autodesk.com/view/RVT/2022/ENU/?guid=GUID-A0FA7A2C-9C1D-40F3-A808-73CD0A4A3F20 The syntax is: if(<condition>, <result-if-true>, <result-if-false>) When PropertyWizard evaluates an if() function, it starts with the <condition>. For example in this formula: if(Level.Name == “Level 0”, “It’s Level 0!”, “It’s some other Level!”)

Revit’s ‘Filters’ feature is great for highlighting elements based on their parameters, but you are restricted in which parameters you can use. For Walls, for example, you cannot use any of these ‘Constraints’ parameters in a filter: PropertyWizard lets you overcome this restriction – because you can set up a formula to copy the values

You can use the instr() function to find text in a PropertyWizard function. It finds the position of one piece of text inside another, and returns the character position of the first character of the found text, or -1 if the text isn’t found. So, say we want to find all the rooms where the

It’s useful if your Revit Levels have a Level Code as well as a Level Name. That way, you can use the Level Code in your formulas for door numbers, room numbers, etc: Level Name Level Code Level 0 00 Level 1 01 Level 2 02 etc. etc. Level Names and Level Codes You could

If you are creating parameters in projects that have Groups, and you are using PropertyWizard, you should be aware of this setting in the Parameter Properties dialog: What does the setting do? Well, it only has an effect if you’re using groups, and it’s only active for instance parameters. For example, imagine you add a

Coordinates are vital, but Revit does not give you many ways to access them. To show them on sheets, you have the Spot Coordinates tool, but if you want to schedule them you are out of luck. Fortunately, PropertyWizard makes it easy to access coordinates. This is a quick walkthrough. Elements in Revit have a

The third tutorial in PropertyWizard Help shows you how to join text values together using the ‘+’ operator:

The third tutorial in PropertyWizard Help shows you how to join text values together using the ‘+’ operator: The ‘+’ operator works differently depending on whether the values either side of it are numeric (numbers, lengths, areas, etc.) or text.
