Nexus Revit Family Standards
Description
Ally is a collection of tools that are useful to BIM managers for monitoring and maintaining standards adherence for the organization. This system is configured in the nexus Portal and runs pre-defined checks on Revit family content in selected libraries. It can also be customized to include standards as configured by the organization.
The checks are performed on qualifying content in a library. This means that of 1000 items in a library, there may only be 250 items that qualify. The primary qualifiers are:
- families of versions greater than Revit 2020
- families that can exist outside of a Revit project model
- families that have not been automatically upgraded (checks the source version only)
Configuring Family Standards
Parameter Standards
- Include Shared Parameter Use in Automated Rating: if a shared parameter file has been uploaded to nexus, it will be used in this check
- Include Custom Parameter Use in Automated Rating: checks for parameters not typically found in families (such as builtin parameters)
- Include Custom Parameter Naming in Automated Rating: checks that custom parameters meet the established naming rules
- Include Parameter Grouping in Automated Rating: checks that parameter groups follow established rules
File Size
- File Size: set a maximum size for the family file and include it in the rating
Sub-category Standards
- Include Mapping in Automated Rating: check that the mapping used follows established standard
- Include Unused in Automated Rating: check if there are unused sub-categories
Reference Plane Naming
- Reference Plane Naming in Automated Rating: check if the reference planes are named according to established standard
Search Result Culling
- Exclude Public Content with Combined Rating Less than Minimum: content from public libraries rated below this threshold will not be shown in search results
- Exclude Org Content with Combined Rating Less than Minimum: content rated below this threshold will not be shown in search results
Common Standards
See Nexus Common Standards for configuration of common standards (applies to projects and families).
Running Checks
In the list of the organization libraries, check the boxes at the beginning of each library that you wish to have checked. When checked, a green plus button will appear in the actions area at the upper right of the list. Click this button to begin the process.
A message will appear stating that a check on the Revit content in the selected libraries will be scheduled. Choose OK to schedule or cancel.
NOTE: The checking process uses Autodesk platforms to run in the background, without user interaction. Each Revit content will be checked for all versions and, depending upon the number of items and service volume, may require several hours complete the run. Because of this, there will not be any status indicating how long it will take or when it will be done. A notification will be sent when complete.
Considerations and Best Practices
- Run the check again if several pieces of content have been updated, however
- Be conservative with the number and frequency of running checks!
- The checks will be performed on all stored versions of the family (2019-up)
- The results of the check and ratings that are stored do not correlate to user ratings
- The check will require quite some time to complete depending on the number of items - consider a trial run on a smaller set of content before choosing several or very large libraries
- The checker will only run once on a content item. For example, if the item is associated with three libraries that have been selected for checking, the check will only be performed one time on that item.
- The checks performed are intended to provide a baseline of quality built from known best practices. In some cases, a manual review is recommended periodically to ensure the results are consistent
