Understanding Lookup Tables in Revit
Lookup tables in Revit are essential tools used to streamline the management of data in parametric modeling. They allow users to set parameters for families based on predefined values, which makes them invaluable for maintaining consistency across projects.
Setting Up a Lookup Table in Revit
To create and implement a lookup table in Revit, follow these organized steps:
Step 1: Locate the Lookup Tables Folder
Before incorporating a lookup table, ensure you’ve located or created a dedicated folder for your tables. This can be customized in the Revit.ini file for versions prior to Revit 2014. Confirm that the folder is accessible and properly structured to avoid any confusion later.
Step 2: Create a New Lookup Table
- Open Revit and navigate to the Family Editor mode.
- From the Manage tab, select the Lookup Tables command.
- Choose to create a new table by clicking the New Icon.
- Select the type of key you want to create; usually, the Single String Key is the most common choice, then click on Select.
- Choose the specifications or template you want for your new lookup table.
- Fill out the necessary fields, including the name and any other required details.
Step 3: Formatting Your Lookup Table
Lookup tables typically store data in CSV (Comma Separated Values) format, which is simple to edit. Structure your data effectively:
- The first column should contain the primary key values.
- Subsequent columns should hold the corresponding values for those keys.
Make sure there are no extra commas, and all values align correctly to prevent errors during usage.
Step 4: Importing the Lookup Table into Revit
After creating your pricing or parameter data table:
- Open the Manage Lookup Tables dialog in Revit.
- Click on Import to open the file selection dialog.
- Navigate to your prepared CSV lookup table, select it, and confirm by hitting OK.
Your lookup table should now be accessible within your project.
Utilizing the Lookup Table
To use the defined lookup table, access the parameters you want to associate it with within your Revit families. You can now reference the table values to drive family parameters, ensuring that when certain inputs are provided, Revit automatically populates corresponding values from your lookup table.
FAQ
What types of data can be stored in a lookup table?
Lookup tables can store static data, including numeric values, text strings, and other identifiers that are used to map parameters across different family types in Revit.
Can lookup tables be edited after being imported?
Yes, imported lookup tables can be modified. However, changes might require re-importing the updated table or adjusting the existing table directly within Revit’s Family Editor.
Are lookup tables compatible with all Revit family types?
Lookup tables are generally compatible with most family types. However, the specific implementation might vary depending on the complexity of the family and the parameters being used. It’s important to verify compatibility during setup.
