Hi Mark, one other note - it definitely helps a lot when you post a specific model along with your question... It's just too hard to figure out what you might be running into with only a text description.

Like your original question here I could only answer in kind of a general way.

Knowing that you were working with spheres and not just something like line curves, makes a big difference.

Actually, Michael, that's exactly what I did to create them in the first place. I drew 3 circles touching in just the way I wanted and then turned them into the spheres and cylinder. Then I realized that the spheres needed to be larger. At that point I should have just started over from scratch but instead I decided to "fix" them. This led me to the situation where I realized that I didn't understand why things didn't work, hence this whole mess.

As for Rhino vs. MoI; they are similar and Rhino is so much superior to systems like AutoCAD that there is no comparison. But MoI is just so much nicer to use than Rhino that...well, I just love it. Even though one might say "If you've got Rhino, how can you justify getting MoI?" Again, ease of use and perception make all the difference.

Again, thanks for being patient. I don't know how you can answer all these questions and still work on the software. Oh yeah, no sleep...
Regards,
Mark

Hi Mark, no problem!

Well, Rhino was my 2nd generation CAD program that I designed.

MoI is my 3rd generation CAD program.

So of course I like to think I have learned over time! :) With the experience of being able to look back, there were a lot of design flaws that I had inadvertently stuck in Rhino which I've been able to correct with MoI.

That's sort of why you get that nicer feeling working with MoI, I was able to "start over from scratch" and fix all kinds of underlying issues.

I originally designed Rhino to run on a Pentium 90 (that's 90 Megahertz!) system with only a wireframe working display. There are still a lot of holdovers in it from that time.

What was the first generation CAD? ;)
And the 4 th CAD will...? :)

Hi Pilou,

> What was the first generation CAD? ;)

First generation was a simple mesh based modeling program called Sculptura.


> And the 4 nd will...? :)

Not sure if I would ever have enough energy to start all over again... ;)

THX for these precisions!

> Not sure if I would ever have enough energy to start all over again... ;)

Lack of energy does not appears to trouble you at all!!

Phfft, thats just 'newborn baby in the house' influenced talk. I happen to be in the same boat and know just how you feel! ;-)

Congratulations Nick!
