Rhino and ZBrush

I've been doing pretty well learning Rhino for the past 3 months.  There are still so many things I don't know how to do, so it alternates between fun and frustrating.  I was just reading a post from 2007 about trying to learn Matrix and how it wasn't very interesting to me.  I think my situation now, living in Korea and not having a studio, is really the only way I can learn it.  CAD is only interesting to me now that I no longer have a studio.

I also started learning another program called ZBrush.  I've been using it for about 2 months now.  It's digital sculpting, it's like working with clay on the computer.  I'm using a Wacom tablet and even though that is a pen on a flat surface, using it with ZBrush still gives me enough of a feeling of working with an actual material that  I think a lot of the skills I learned sculpting with real clay and wax have carried over.  It's a lot of fun but still frustrating in its own ways.

This pic is something I've been working on in ZBrush, following a tutorial on DigitalTutors.com.  It's about half finished.

The hardest part about learning this software (both Rhino and ZBrush) is being a total beginner at something again.  With metal I have always tried to keep learning new skills, and how to work with different materials but every time I started something new I was already bringing all my previously learned skills to it.  For example, at the time I took some machine shop classes, learning to use machine tools (lathe, vertical and horizontal mills, surface grinder) was very different from all the hand work I had previously done in metal.  But I was able to pick it up quickly because I already had about 10 years as a craftsman.  Working on the computer everything is new.  I said earlier in this post that I felt that the experience I had sculpting with real materials helped me ZBrush, but there's so many other things to think about when using the software that make it complicated.  And with Rhino, nothing I have learned previously helps me with it, except for design considerations.
