I do almost all of my modelling in Carrara's vm and although symmetrical modelling would have been nice , what they have added is much more valuable to me as a modeler. The new Extract edge tools,bevels,soft selections,the new selection tools and all the polyline tools and Gordon,Ruled surfaces,coon surfaces the manipulator... It is a long list of what they added. I will be very happy with using the duplicate with symmetry trick to mimick symmetrical modeling.
