having difficulty exporting Skp Pro 2021 to Revit 2021. seems some steps are missing in tutorials because of newest software. Help!
Try first saving your SketchUp model as an older version SketchUp file. I am not certain which version is supported by Revit 2021 but it was released before SketchUp 2021 so it almost certainly doesn’t support the newest file format.
What is your goal? Are you using your SketchUp model as a mass model template in order to add Revit objects “on top”? As Revit is based on a “solid” modelling concept and Sketchup is face geometry, there is no direct way of converting SketchUp objects into editable Revit objects.
