Issue:
When trying to load a model in Autodesk® InfraWorks™ the loading process stops and an error message appears:
InfraWorks is unable to render your model.
This can happen while rendering models with high display detail and quality. Try reducing display settings in Application Options.
Causes:
InfraWorks 3D options are set up for displaying more details than the hardware can handle.
This can also happen when a video card, such as Intel 4600 have trouble with 4K monitors.
Solution:
- In the Application Options make sure to set up following options before opening/loading the model:
- Model Generation: Building Facade Detail = Low
- 3D Graphics
- Optimize for speed
- Display Detail = Low
- Turn off all effects
- Show Backfaces = Off
- If the model opens with these settings the options can be raised for displaying more detail step by step
- Delete generated surface tile cache. The location of this can be found in application options
