I have imported an architect’s IFC file, which they exported from Revit for me. After importing the IFC file into SketchUp, the resulting model behaves very oddly, rendering it unusable for both modelling in SketchUp and drawing production in Layout. All geometry appears to move slightly as I navigate around the environment and when viewed in plan, elevation and section. This creates linework that appears in a random pattern (see sample images). When a component is exploded down to un-grouped geometry this behaviour stops for that geometry only (see sample image), but persists with unexploded components.
I’ve experienced this issue before but never to this extent. The IFC file is fine when viewed in Trimble Connect, so I don’t think the file is corrupted. The issue happens both with a native import and using SimLab IFC Importer.
The attached sample file is a window extracted from the main model to demonstrate the behaviour. Is it possible to overcome this issue without exploding the entire model (66MB), which is not an option for workflow reasons?
