Sometimes it is more convenient to adapt the configuration directly in the \*.calc file without using the Wizard.

This is how you do this:

1. Open your collaboration project in AutoCAD Plant 3D
2. Open the Calculation Main Dialog
3. Select the configuration you want to modify
4. Click on the **Edit** button to open the Wizard This checks out the \*.calc file.
5. Click on **Cancel** to close the Wizard The \*.calc file will still be checked out. Do not close the Main Dialog yet.
6. Open the \*.calc file under \[PROJECTFOLDER]\ACPlantTools\PlantExpressTools\Calculations in a text editor
7. Make your modifications in the file and save and close it
8. Click on **Refresh** in the Main Dialog This will read the \*.calc file again so you see if there are any error in the file.
9. Close the Main Dialog This checks in the \*.calc file.
