Rhino model has broken/distorted

I have started making a rhino model and this happened. I am not able to select the lines that come off of the model. I have tried closing and reopening the document and copying the model over to a new document but this did not work. Any help would be much appreciated!

Looks fine here on Rhino V6 for Windows. I seem to recall this type of problem on MacRhino a long time back. What version of MacRhino are you running? Can you run the SystemInfo command in Rhino and copy/paste the results here?

Sorry for the late reply. It managed to sort itself out. Just updated Mac and restarted!
