As an addition to the Illustrator export it would be really helpful if there was a 'centre geometry' on export selected.
The current set up works well and there is no dent in the work flow. You draw something, export it and you can update and export with things opening in the same location. This is of paramount importance 80% of the time.
Often though a quick export of something is required where you don't need that location or precision, you just want it centred on the art board.
As an example, if you have lots of models and versions in your Rhino model space and you want to export some text or curves to Illustrator it can be too far off the art board when opened in Illustrator and can't be moved to the centre.
The only way I've found to get around this is to move the thing you want to export to the world centre before export. The addition of a tick box to centre geometry on export would be so very useful!
