I am unable to save my file due to the following error message - “SketchUp has encountered an error while saving this model” This has persisted over two days with multiple attempts. I am able to download the model onto my desktop, but unable to save it. Please advise.
So you’ve got the file already stored somewhere (previously), to be able to download the model to your desktop. My advise: please share it here so others can look at it.
