Working with parameters in Revit is essential for managing and organizing data efficiently. Parameters control the information within elements and families, making it easier to schedule, filter, and modify objects. Here's a breakdown of how to work with parameters in Revit:
1. Types of Parameters in Revit
Revit has different types of parameters:
a) System Parameters
Built-in parameters that come with Revit (e.g., Level, Family, Type Name).
Cannot be deleted or modified.
b) Project Parameters
Added at the project level to multiple categories of elements.
Used for scheduling and filtering but cannot control element behavior.
c) Shared Parameters
Can be used across multiple projects and families.
Essential for tags, schedules, and interoperability.
Stored in a separate .txt file for reuse.
d) Family Parameters
Specific to a Revit family and control its properties.
Exist only within the family and are not visible in schedules.
2. How to Create Parameters
a) Creating Project Parameters
Go to Manage tab → Project Parameters.
Click Add... and choose a name for your parameter.
Select a discipline (e.g., Common, Structural, Mechanical).
Choose a parameter type (e.g., Text, Number, Yes/No).
Assign it to a category (e.g., Walls, Doors, Floors).
Select if it’s Instance or Type based.
Click OK to apply.
b) Creating Shared Parameters
Go to Manage tab → Shared Parameters.
Click Create... to generate a new .txt file (if not created already).
Click New... to add a parameter inside a group.
Assign a discipline and data type.
Click OK, then add it to Project Parameters or Families.
c) Adding Parameters in a Family
Open the Family Editor.
Go to the Create tab → Family Types.
Click New Parameter... and define its properties.
Use formulas to control values dynamically.
3. Using Parameters in Schedules
Go to View tab → Schedules → Schedule/Quantities.
Choose a category (e.g., Walls, Doors, Floors).
Click Add Parameter to include project or shared parameters.
Use Filters & Sorting to manage data.
4. Instance vs. Type Parameters
Feature Instance Parameter Type Parameter
Affects individual elements ✅ Yes ❌ No
Affects all elements of the same type ❌ No ✅ Yes
Editable per element ✅ Yes ❌ No
Used in schedules ✅ Yes ✅ Yes
Instance Parameters are best for elements that need unique values (e.g., door height per room).
Type Parameters are best for elements with standard values (e.g., all doors of a certain type should have the same width).
5. Tips for Working with Parameters
✅ Use Shared Parameters for consistency across projects.
✅ Use Type Parameters for elements that rarely change.
✅ Use Instance Parameters for elements that need individual customization.
✅ Use Formulas to automate calculations inside family parameters.
