This is the reason that I would use SW to create tubes.  They are easy to
 cut using a surface created on the face the the adjoining tube. After the
 ends of the are cut, they can be exported as an IGES file, which, if
 brought back into SW, will automatically form a solid again.


  BTW Gary, did you ever work in car racing?

 I was at Chaparral for several years and also McLaren. :-)

 That is amazing. You were there just before me. Small world now.
 You and I ought to co author a book. When did you leave McLaren?
 Did you go to the Oxford World Motorsport Symposium in 2008?
 Last time I saw Jim was at Phil Hill's funeral.
 His son has a go cart track near me in Ventura.

I left McLaren Engines at the end of 1987.  I didn't go to the Symposium
in 2008.  I left Chaparral (the first time) at the end of 1964 and joined
McLaren in England.  I was back at Chaparral in '69 & '70 and then went to
McLaren Engines in Livonia, MI.

Gary, You will get a kick out of this picture. Teddy is copying my
quick jack design at Daytona  in 1965 (as I recall).
Scat AKA Carroll Smith worked for Ford at the time.
Who is the guy on the right?
He may have been a Chaparral mechanic?
