CAD program update


Hi Tom,

Ian, I don't mean this as a personal attack, but what you wrote in
your post concerning Rhino is complete misI am
wondering if you have spent much time with the program? >> 

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

Rhino is not, and never will be a parametric CAD program. If I
want to move a hole in a surface, I have to do it manually and then
rebuild the surface. If I want to resize an object, I have to do
it by scaling, not by typing in new dimensions as you would in a
parametric program.

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 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…

Best wishes, Ian –

Dear Ian I am Interested in the discussion on via ganoksin regarding
Rhino CAD. I have been using truspace for 5 years now and produce
most of my design work & image creations an examples of which are on
my website intro page. I have heard of Rhino as used
by Hockley mint & presumably yourself. I am reluctant to change as
Truspace is extremely efficient at producing virtual jewellery to
show my clients. It does however sound very similar to solidworks. I
am not at this time bothered about converting the images to CAM, but
it is possible. I would be interested in playing around with trial
version of rhino or solidworks. Do you know how I
can access a trial version of either? Regards Ian Davidson


Ian, I can help you out with the Solidworks demo disk. That goes for
anyone else interested also. Best Regards. Neil George 954-572-5829



As a dedicated Rhino CAD user I have no hesitation in recommending
it - partly because of its capability and ease of use and partly
because of the fantastic user group forum - questions answered
rapidly, free flow of ideas etc

You can download free trial versions of Rhino at and see galleries of jewelry and
other stuff produced with it.

And you can use Rhino with solidworks.

Good luck
