Below is a list of known issues within Ideate BIMLink. Please also refer to Unsupported Revit Properties for related information.
The user is not given an Import Issue for columns overwritten or changed by bidirectional parameters in columns to the right. This would occur if custom family file contains a parameter that uses a formula which is driven by another parameter value within the family. Ideate BIMLink will not report the change to that formula-driven parameter when it is listed to the right of the (parent) parameter. Another example of bidirectional parameters is Elevation and Offset: changing one impacts the other.
Any conditional formatting will be lost when the source data is overwritten.
Generic Model elements and Masses can be re-located IF they are not hosted in such a way that would prevent such movement. The coordinates can only be edited from a their respective category links and cannot be edited from a Multi-Category link.
Excel Tables and Duplicate Parameters
If the Excel data is converted into a Table AND if there are duplicate parameter names, Excel will rename the Column header with an incremental number suffix. This renaming will cause the Import from Excel to fail.
Changing Family Names
Type-based links allow both the Family Name and Type Name to be edited. If multiple new family names are entered for the same family types, the last family name change wins. Ideate BIMLink does not permit the creation of new families nor does it permit the consolidation of multiple families into a single name. Related Topic: Utilize Type Swapping
Changing Type Names
Revit does not permit the duplication of type names. Renaming a type name to match another type name within Ideate BIMLink will cause Revit to create a new unique type name by appending a number to the duplicate type name. Related Topic: Utilize Type Swapping
Ideate BIMLink can distinguish between family based non-shared parameters and project non-shared parameters with the same name. If the family based parameter is defined with different parameter types between families, Ideate BIMLink will convert all values to text for storage in Excel.
Families with no Types
Ideate BIMLink cannot export a type for a family that has no types defined. A family that has no type defined will display within an Instance link (if an instance has been placed), but will not display within a Type link.
Filtering by Levels
The ‘above’ and ‘below’ filters are not conventionally handled due to differences between how Level and Level:Elevation. For tips on how to filter by level, refer to Ideate BIMLink Messages.
Linked File Limitations
Support for Linked File data has been added with the October 2014 release of Ideate BIMLink. While coordinate data can be reported across linked files, coordinate data is reported in the context of the project the element is found in, therefore coordinate data will only be useful if the projects are using Shared Coordinates.
Additionally phase information from the linked file is ignored, meaning that all elements, regardless of the phase or phase filter setting, are included in the export. Elements that are found within the parent file will abide by the phase filter settings. The Ideate BIMLink filter tab can be used to explicitly filter on "Phase Created" as a workaround to this limitation.
Missing Sheet and View information for Schedules and Legends
In Ideate BIMLink the View category includes information about Schedules and Legends. This differs from the Revit View List which excludes these Views. Views can include properties about both the Sheets and Views, as is shown within the Sample Link called "Views".
Ideate BIMLink, and Revit, cannot report values for the Sheet properties for Legend and Schedules, because both Legends and Schedules are permitted to exist on more than one sheet.
Ideate BIMLink may display fewer mullions than a Revit schedule because Ideate BIMLink excludes mullions that have no geometry. These mullions will display in a Revit schedule and will show a "0" length. We thought it would be nice if we just excluded them.
At present Ideate BIMLink can report on the name of a nested family but this choice of a family cannot be edited.
Phase Data for To: Room
The Revit API does not provide information about the Room Name for elements that use To: Room and From: Room properties (such as doors) when the phase of the element (door) is not the same as the phase of the Room. For example, if the Room was created in the existing phase, and the Door is new, then Ideate BIMLink cannot return the name of the room.
Room: Name for Spaces
Ideate BIMLink has the ability to report on the related Room Name and Room Number as it relates to a Space when it is reading across a linked file to a project that has a spatially aligned Room element. These properties belong to the Space category and are called "Room Name" and "Room Number". If a link is created from a Space-based schedule that utilizes the "Room: Number" and "Room: Name" properties, Ideate BIMLink will report these (different) properties as being blank. The workaround is to remove these properties and add the "Room Name" and "Room Number" (no colon). These properties are only available when a linked file is being used. For more information refer to Reporting_Spatial_Data_Across_Linked_Files.
NOTE: If there is no room in the same document of the same phase, Revit is reporting a room from a linked file, or "Unoccupied" if there is no room in a linked file. We are reporting room data from previous phases.
The level of precision with certain properties can result in unexpected sorting results. As an example, the Wall Orientation, or other angle properties, may appear to be at 0 degrees, but in fact there's a small difference within the Excel cell that may not be perceptible until it's reviewed by selecting the cell within the Excel environment (0.000000000001). This small difference may return unexpected sorting results. In this case you may need to use the ROUNDUP function within Excel to alter the values and then re-SORT.
Unexpected Read-Only error for System Properties
If an element is part of multiple systems (e.g a heat pump can be a part of electrical, air, and water supply systems), BIMLink will return the selected parameter value of the first system.
When importing equipment with multiple systems back to Revit, you may receive a read-only error, because BIMLink may not be able to tell to which of the multiple connected systems a parameter belongs.
In-line text formatting which is added through the "Modify | Text Notes" tab within Revit, and includes options for bold, italic, underline, bullets, and numbering is not recognized by Ideate BIMLink as special text and will be removed upon re-import if the text is changed. This is an API limitation, unfortunately. Workarounds include manually adding bullets or numbering OR using the Filter method within Ideate BIMLink to exclude text placed on Sheets or Views where this type of formatting has been used.
