Frequently Asked Questions
How do I get help making my own checks and checksets? You can install and use the Model Checker Configurator to do this. For more information, visit the Model Checker Configurator help page.
Why is my Excel report export file is missing data/why is some of the data truncated?
Excel has a known character per cell limit of 32,767. In extremely rare cases, parameter or other information exported from the AVT Task to an Excel report has resulted in data longer than the limit. In these cases, the data is truncated in Excel. Review the Revit model directly for actual values.
Why does my report never complete?
Some checks are known to run longer than other checks. On particularly large models, this may cause AVT to time out and not complete the check. It is recommended to disable these checks for AVT runs or troubleshoot using the desktop Model Checker for Revit to identify the specific check.
- Largest Family Pre-Built Check
- Duplicate elements checks
In addition, very large or problematic models may cause AVT to time out. It is recommended to review and clean up these models in Revit on the desktop and test time to run your checkset using the desktop Model Checker for Revit
Can I edit a Task or review reports that another user made directly in AVT?
Tasks and uploaded checksets are tied to the user account that created and uploaded them. There is no way for a user to review or modify AVT tasks or checksets created by a different users.
Why can't I change the models or checkset when I edit a task?
Editing an existing Task does not allow the modification of that Task's selected models or checksets. This is to maintain data fidelity between runs. There will be a consistency of sources and checks for any Report generate from an individual Task. Users can duplicate a Task to start from an existing Task with similar settings but needing to change models or checksets.
Why is my Excel report not being created/exported/saved properly? Microsoft Excel has a limitation with regards to the amount of data it can hold. It is approximately one million rows of data. A report that consolidates the results of many models could reach this limit. AVT may not be able to successfully report this error and will simply not create the Excel export. If you suspect your Excel file may be over the row limit, reduce the number of models included in the report and try again.
Why do the checks for Survey Point and Project Base Point in the Best Practices checksets always fail when run from the Public Library in AVT?
When the checks are run directly from the Public Library in AVT, they fail because the default values for the coordinates are 0. They need to be modified for the specific coordinates that are applicable to your project. Open the checkset from the Model Checker Configurator and save a copy. Then edit the default values in the checks to the desired coordinates for validation. The values have to be copied from the “AsDouble” value found by using the Revit Lookup add-in, instead of the “AsValueString” value, which is the coordinate value that is visible from the properties in Revit.
This article explains how to find and copy the “AsDouble” values.
Once the default coordinate values have been updated, save the custom checkset and upload to the task in AVT.
