Navisworks Setting Guideline #
User may encounter problem when opening IFC file exported from MiTS into Navisworks.
As written in Navisworks’ Forum, there are some setting that will require some adjustment in order to allow Navisworks to be able to open the IFC file.
Suggestion 1: Turn off the ‘Revit IFC’ #
In Navisworks Options > File Readers > IFC, unchecking Revit_IFCs if these are not from Revit
Suggestion 2: Try to toggling Hardware Acceleration off (or on if currently off) #
In Navisworks Options > Interface > Display > Hardware Acceleration
Suggestion 3: Redo the IFCs #
User may return to the source of these IFCs and check the export setting.
As in this case user may need to change the compatibility of ‘Schema Version’ to IFC 2×3 or IFC 4 in MiTS Parameter setting.
Suggestion 4: If working in large coordinates (super far from 0,0,0) test in a new Navisworks file not using large coordinates. #
Why need to use schema version IFC2x3/IFC 4 in Navisworks Manage 2019?
Currently, IFC4x1 schema version is compatible with most BIM-Compatible Software but that is not the case for Navisworks Manage 2019. For Navisworks Manage 2019, user may refer below for ‘Supported file formats and applications for Autodesk Navisworks’
Note:
- The default schema version when BIM Export function used is IFC 4
- IFC 4 cannot export road alignment– it can only be exported in IFC 4×1.
- In the software, road export will be greyed out if any format other than IFC 4×1 is selected.
