Talk:Calma

Old talk
I just created all the content you see on this page. For some reason, my user name did not get attached to the edit, so I'm making a trivial edit now so that my name will be on it. -- tomtab Tomtab 02:11, 31 August 2005 (UTC) A possible reason is that you were away from the wikipedia editing for a longer time, and the session was timed out.

I am glad that someone remembers pioneers of the industry. I hope that your text does not constitute a copyright violation, i.e., it is not a verbatim copy from non-public sources. I apologise if this remark offended you, but this is a common mistake of many newcomer editors of wikipedia. See copyrights. For this particular case: by law, facts are not copyrightable, but their descriptions are. Therefore it is adimissible to rephrase descriptions you see elsewhere. mikka (t) 18:00, 3 September 2005 (UTC)

The quoted material is from an SEC filing, and as such should be in the public domain. I would not have included this quote if it were from a document readily available on the web, but since it is from 1978, I rather doubt that this is the case. I don't like resorting to quotes, but until such time as we can add detailed descriptions of the Calma products to Wikipedia, it seemed like a reasonable place-holder.

Irma
Irma of Calma died in 1992. The daughters no longer have the flower shop. Jeff Milde (Cal and Irma's grandson) 66.92.12.200 21:25, 1 May 2007 (UTC)
 * Sad. Any proof, so that this info may be added into article? `'mikka 06:35, 2 May 2007 (UTC)

Irma Louise Hefte died 9/27/92, in San Jose, Calif. CC of Death Certificate on file in Santa Clara Co. #537853. Calma began as a Manufacturers Representative Company in 1962, from the 4th bedroom of the family home on Amby Drive in San Jose, Ca., prior to its incorporation. Calvin took care of sales, Irma acted as secretary and daughters Sheri and Barbara filed and stamped literature to promote the family business. Irma, Sheri and Barbara were partners in a Los Gatos Flower Shop, Carousel of Flowers. The shop was sold when Irma became ill the year prior to her death. Sheri lives in San Jose, Ca and Barbara in Westminster, Colo. Calvin and Irma have 5 surviving grandchildren and 3 great-grandchildren in addition to their daughters and 2 son-in-laws.Sherimilde 16:27, 2 May 2007 (UTC)Sheri Milde (Calvin and Irma's daughter)
 * Thank you. In wikipedia there is a rule ("cite your sources") that added info must be referenced from reliable sources, therefore I asked for proof. Are there any books or journal articles or other documents that cover biographical details? If you are around Sunnyvale, CA, we can talk in person, if you e-mail me by clicking here--> Special:Emailuser/Mikkalai. `'mikka 19:08, 2 May 2007 (UTC)

Tom Hedges
Tom Hedges, one of the architects of the GDS II system, died on November 16, 2007 at age 57. At his memorial, his widow expressed a wish for his name on this page to link to something. Accordingly, I have added an external link to his obituary. If anyone can think of a more appropriate link for him, I would welcome it.Tomtab (talk) 03:13, 29 November 2007 (UTC)

David Weisberg on-line book
A big motivation for starting this article was the fact that virtually no information about Calma was available on the web. With the appearance of David Weisberg's on-line book (referenced in the article as [WEI08]), that situation has changed dramatically. This meticulously researched book includes a 27-page chapter just about Calma. This is a rich source of information for filling in some of the gaps in this article.

The biggest of these gaps is in the description of Calma's products. What I propose to do is to create a separate subsection under "Products" for each market segment: mapping, electronic, mechanical, AEC,... with the hope of describing under each of these the succession of products Calma offered in that segment over the years. This won't happen at once -- at least not from me. I can start on the areas I know best (electronics). I hope that others can continue to fill in details of areas they are familiar with.

ComputerVision lawsuit
I have just deleted the paragraph about the 1977 ComputerVision lawsuit. Although this lawsuit loomed large at the time, I feel that. viewed from the perspective of the overall history of Calma, it is probably not important enough to merit inclusion in this article. I'll be happy to reconsider if anyone feels strongly otherwise. —Preceding unsigned comment added by Tomtab (talk • contribs) 20:36, 15 August 2008 (UTC)

CADDS 5 vs Dimension III
I just deleted from the History section the statement that Dimension III was merged into the CADDS 5 product, because I found a number of web pages indicating that Parametric Technology marketed Dimension III and CADDS 5 as two separate products. Maybe I've misunderstood something, in which case I will appreciate any clarification.

Also, I'm curious about the statement in the Product section that Parametric Technology was still supporting Dimension III in 2006. Is there any evidence that anyone was still using Dimension III in 2006? That would certainly be worth mention -- as you can see in my edit to the Intro section today, the latest I could find evidence for was a reference in 1998 to its use at Ingalls Shipbuilding.

Calma DDM/ Dimension III - A couple of the latest known users.
GM still used at least one seat of DDM until approximately 2003. This system was dedicated to camshaft design. The special software was developed by a small group at CALMA/ Southfield, MI. This software would take camshaft lobe data along with a series of questions from the designer, then automatically create the finished camshaft design, casting design, tooling design to manufacture foam patterns for lost foam casting process, and create all machining CNC cutterpaths for the tooling. This reduced the original process from 3 months utilizing DDM, to 1.5 hours. The programming was done utilizing DAL (Design Analysis Language), a powerful high level programming language which was part of the DDM system.

As of the early 2000s, Cummins was still using DDM for legacy designs.

The DDM system was way ahead of its time. Every CAD command was also a function in the DAL programming language. The system had parametrics and solid modeling, along with a strong NURBS surfacing capability. While these capabilities were very forward thinking, most users were migrating from drafting boards and most never used the full power of the system.
