Common Revit Warnings

If you are looking to to reduce the number of warnings in your Revit project, but do not have a lot of spare time, here are a few simple examples of how to fix some of the most common Revit warnings with Ideate Explorer.

Duplicate Mark / Number

The Duplicate Mark (or Number) warning is one that is likely not a performance-related warning. Mark and Number (for Room/Space) values are required to be unique for COBie deliverables, and can also be required as part of an owner-mandated deliverable criterion. The consequence of not resolving this warning type is between you and the person paying for the deliverable.

A Duplicate Mark warning means that within a given data category (Doors, Mechanical Equipment, Structural Foundations), each instance has a value for the “Mark” property, and at least one value is not unique.

Duplicate Type Mark

The Duplicate Type warning is, one that is likely not a performance-related warning. Type Mark values are required to be unique for COBie deliverables and can also be required as part of an owner-mandated deliverable criterion. 

Unlike Duplicate Mark, the Type warning is a bit harder to resolve via Ideate Explorer, because while the Type itself can be selected and displayed in the Properties palette, the type is not editable in this mode. For this reason we are recommending that either a Revit Schedule or Ideate BIMLink be used to resolve this condition.

Identical Instances

The Identical Instance warning is important to resolve as it will create inaccurate schedule and quantity takeoff information, exposing the project to liability. The good news is that this warning type is very easy to address with Ideate Explorer and you can review and fix the warning right from the Ideate Warnings tab:

  1. Select the elements from within Ideate Explorer on the Warnings tab.
  2. Use the Revit Selection Box to make a 3D view 
  3. Use Temporary Hide/Isolate to Isolate the identical instances.
  4. Select each of the paired identical elements from Ideate Explorer to decide which should be deleted.
  5. Select the element(s) to be deleted, then use the red “x” within Ideate Explorer to delete, or, if you have IdeateApps, use SmartDelete to review the safety of making the deletion.

In the most recent update to Ideate Explorer, you can choose to fix ALL Identical Instances by either Retaining Originals or Retaining Latest. Learn how to Delete ALL Identical Instances.
