Change Rhino 3D Drawing Units

I always start a drawing and forget to change to inches. Is there a way to convert my drawing to inches after it is started?

You can change the units in the DocumentProperties>Units page and click No on the box asking if you want to scale the model. But it would be easier in the long run to start a new model (New command) and in the Open dialog, which will bring you to the template directory, choose the inch file and check the little box that says Use this file when Rhino starts. That way you will always fire up Rhino in Inches. - Pascal Rhino Newsgroup
