Revit’s schedules are very powerful, but there are some parameters that you cannot schedule. For example, you cannot schedule the ‘Top is Attached’ or ‘Base is Attached’ parameters on walls:

PropertyWizard treats Revit’s Yes/No parameters as True/False boolean values. So it is easy to use Yes/No parameter values in formulas, and it’s easy to set Yes/No parameters from formulas. Using Yes/No parameter values You can use a Yes/No parameter value anywhere that is expecting a True/False data value. So you can use them: As theRead more “How to work with Revit’s Yes/No parameters in PropertyWizard formulas”

Expressions are the building blocks of PropertyWizard formulas. They are like phrases in a language. It’s useful to understand the different kinds of expressions in PropertyWizard, so you can put them together in different ways to write better formulas. There are four main kinds of expression in PropertyWizard: Literal expressions Identifier expressions Operator expressions FunctionRead more “Expressions in PropertyWizard for Revit”

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, andRead more “How to filter Revit elements using an if() function”

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!”)Read more “How to use the if() function in PropertyWizard for Revit”

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 valuesRead more “How to fix Revit’s Filters with PropertyWizard”
