Hi Tom,

    I stand corrected ;o( 

    I must admit I have not used the latest version of Rhino although I
    have done quite a bit of work using vesion 2  - what this post does
    illustrate quite clearly is that, without regular updates and serious
    training, it is easy to miss significant changes in such programs. 

    I used Autocad for over 12 years at work, doing quite a bit of 3D
    stuff, before I 'found' Rhino and, at the time, I was quite impressed
    with it. The ease with which you can draw in a multi-viewport
    environment was quite refreshing. However, maybe since I came from a
    'traditional' CAD background I've never been a fan of mouse-driven
    CAD programs and have always regarded them as slow and too cumbersome
    for a production environment. Perhaps this is how I came to miss the
    features that Tom describes. I obviously need to do some more
    research....

    This, however, is the main difference between Rhino and Solidworks
    (or their equivalents) and is what I was trying (awkwardly) to
    describe in my previous post. With the new generation of parametric
    programs your starting point is, effectively, a block of material
    which you sculpt on the screen and, if you want to change the size or
    any other property of a particular feature, you can do so by simply
    bringing up its 'properties' box and changing the information in it
    rather than, in the more 'traditional' CAD, having to go back several
    steps to change and then rebuild the model. 

    I did not mean my previous post to denegrate Rhino in any way, it is
    a good program and each type of CAD has its place in which it
    excells. More often than not, the ease with which a program works is
    directly related to the cost of the program and so, the more you are
    prepared to pay, the easier life will get ...... except that you then
    have SOOOO many more 'bells and whistles' to learn about....
