Import Formit to Revit 2019 is "unresponsive"
Accepted solution
Hi jroyMFZU3,
When converting a SketchUp file to FormIt, you'll want to do a few things to make sure the file is clean and ready before sending it on to Revit:
- Models should be watertight/solid before sending to Revit. In FormIt, use shortcut DW to display watertight issues in the file. This can also be found in the Visual Styles panel on the right (sunglasses icon) under the Diagnostics tab. Try using it in conjunction with Monotone Mode (shortcut DM) to make the lines more clear.
This will highlight any edge that is not contributing to a solid model (also known as a non-manifold edge), and may need to be deleted, or the face needs to be extruded, or an adjacent face needs be drawn to ensure the model is solid and watertight. In some cases you may just need to extrude a flat surface into a 3D solid. For 3D shapes, you can try selecting edges that are non-manifold and use FormIt's Cover tool (shortcut CV) to try and automatically draw the adjacent face that is missing. You may need to employ a mix of Cover tool and manually drawing lines to get faces to appear.
- As part of ensuring the model is solid/watertight, you should check the Display Back Faces diagnostic too (shortcut DB), which will highlight the backsides of faces in red. We also recommend using this in Monotone Mode (shortcut DM). These back faces should always face towards the inside of a solid, so you don't want any of these red faces oriented outwards. When covering solid models, FormIt should automatically flip the faces, but you can flip them yourself by selecting them and using shortcut FF. You can also invoke Reverse Face from the context menu.
Attached is a quick Screencast showing how to use Monotone Mode, Display Watertight Issues, and Display Back Faces diagnostics in conjunction to correct a simple SketchUp model that exhibits all of these issues. Before sending your model to Revit, you should see no red lines or red faces when using these diagnostics in Monotone Mode - this is a way to check the model is clean and ready to go.
- Finally, try converting the FormIt model to Revit in smaller pieces. The conversion process is intensive and can result in Revit hanging if you try and convert very large or complex models in one step.
Hope this helps,

Not sure the Screencast came through the first time, so adding it here just in case.
