Revit Based HydraLIST (Ribbon/Toolbar/Location)

Button: Auto Stocklist Error Type: Command Failure for External Command

Description:

This error appears immediately when trying to run Auto Stocklist, the dialog box never appears. 

Revit could not complete the external command... System.NullReferenceException

Solutions:

Cause:

The AutoList application is looking for some calc parameters that don't exist for some fittings / devices in your current system. 

Solution:

Run the Setup button from the HydraCALC ribbon then attempt to run the Auto Stocklist command again, and it should work. 

This issue will be fixed in a future program update so this workaround is no longer required. 

If you recieved this error, and the listed solutuon doesn't fix it for you, please contact support at revitsupport@hydracad.com
