Error Messages Reference

This article lists all known error and warning messages with their cause and recommended solution.

Errors When Loading Shortcuts and Files

Note: Load errors are warnings — affected rules are still loaded but with missing or default values. Always verify rules after loading.

Message	Cause	Solution
Scope Box not found (Row X)	The saved Scope Box or SolidFilter does not exist in the current project.	Manually reassign the geometry filter of the rule.
Category not found (Row X)	The saved category is not present in the project or has a different internal ID.	Select a different category in the rule.
Invalid geometry filter mode (Row X)	The saved mode is unknown — possibly an outdated file.	Set the geometry filter mode manually.
Invalid data source (Row X)	The saved data source is unknown.	Set the data source manually.
Invalid parameter mode (Row X)	The saved parameter mode is unknown.	Set the parameter mode manually.
Invalid value (Row X)	The saved value does not match the parameter type.	Check and correct the rule value.
Invalid value type (Row X)	The saved value type is unknown.	Re-select the target parameter; value type will be re-determined.
Invalid SolidFilter	SolidFilter could not be initialized (missing geometry).	Check the SolidFilter in the SolidFilterTool or select a different filter.

Message	Cause	Solution
No parameter set	The rule has no target parameter — it is incomplete.	Select a target parameter.
No value	No value entered for a non-Text parameter.	Enter a value.
No elements found	No element in the project matched the filter criteria.	Check data source, category, and geometry filter. Are there any elements of this category in the model?
No parameters found	Found elements have no writable parameters.	Check category, parameter mode, and project parameter bindings.
Parameter not found	Target parameter not present in found elements.	Re-select the target parameter.
N parameters not written	Revit rejected writing for N elements: formula binding, read-only category, invalid unit value.	Check if the parameter has a formula binding. For doubles: verify correct unit.
N elements do not have the parameter	N elements in the found set do not have this parameter. Typical with mixed families.	Expected if mixed family types. Otherwise check project parameter bindings.
N elements locked	Worksharing: N elements could not be checked out — another user holds them.	Wait for other users to release them, then retry.
Checkout failed	The worksharing checkout failed entirely (connection issue).	Check connection to central file. Restart Revit if needed.
No elements checked out	Checkout ran but none of the needed elements could be acquired.	All elements are held by others. Wait and retry.

Message	Cause	Solution
Revit version error on startup	DLL compiled for a different Revit version than installed.	Use the correct build for the installed version.
License dialog on startup	No valid license found.	Obtain or verify license from Planworks GmbH.
Add-in does not load (no Ribbon tab)	Wrong DLL path in .addin file, or file in wrong folder.	Check and correct the Assembly path in the .addin file.

Message	Cause	Solution
"Invalid value"	Entered value does not match the parameter type (e.g. letters in an integer field).	Correct the value for the parameter type. For formulas: check the expression.
"Reserved value"	The text `<No Value>` is internally reserved and cannot be set as a text value.	Use a different text value.
"Not a single token"	The Pattern Parser expression for a Yes/No parameter is not a single token.	For Yes/No parameters, use only simple tokens without concatenation.
