We made steelwork look correct but there was no structural catalogue at that time.
The nearest we had were individuals own Macros.
No PML back then either.
Thanks for sharing the history of the early days - now I know why there were different modules.
I assume PASCE was a copy of PDMS from the earlier days? Do you know that part of the history?
While the design/spatial layout was in a few good designers then(who I assume communicate with each other via 2D drawings), what's happening now is a whole bunch of "designers" put a lot of garbage in and expect PDMS to produce clash-free design for them.
If you ever talk to ***, tell him that the datacon is still quite robust with a very large project (10+G) however the peripherals (communication, tcp/ip) are not as bullet-proof. Please continue to share the history with us. I hope some of these gets move to the wiki for Plant Design Management System some days.

The pipe auto-router program still cannot read mind yet.
Mike, I can tell you why they do not allow people to change their own posts.
Mike,
If you were to design a new architect for PDMS to enable work-share around the globe, how would you/*** go about doing it?
How about if the client request pipes to be modeled in city H, but pipe supports to be modeled in city B? This might not be the best work-breakdown, but it was constrained by economics/schedule etc. What kind of check/balance should be built within the "extract" db?
I assume you are familiar with PDMS extracts - it enables user A in city H to work on the pipe and as well as user B in City B to work on the pipe support (on same pipe) via extract and with a claim/flush process. However due to the communication limitations(firewall etc), packet maybe lost during the trip and thus locks up the pipe so no one can work on it.

All the program modules and a decent-sized demonstration design would easily fit onto the standard Prime 3MiB removable disk -- and the whole operating system and compilers, utilities etc fit into a 3MiB fixed disk too.

Amazing.
What's more amazing is that we have access to 3G memory on XP but somehow manage to use it up via lousy programming.
Just checked the other day that a one TeraByte external HD is only $60 in the electronic store. Wonder how many decent size plant we can fit on it now...

Sorry, I have never heard of Pasce before, and Google finds very little.
My involvement with PDMS ended in 1980 when I rejoined the original development team who had started a new business called Cambridge Interactive Systems.

I'm not a software architect, so it's not really something I can answer. But the largest world-wide co-operation I can think of is the Linux kernel and all the surrounding programs, so I'd take a look at how that is organised.

I'm not familiar with "extracts", but this is a problem that has been solved many times over by the big commercial databases. At big cost of course. I've no idea what PDMS costs now, per seat, but would the customers also pay the extra for Oracle etc? They are not cheap at all.
PASCE - Plant Applications and Systems for Concurrent Engineering. It was bought by Cadcentre in 1999. DOW chemical may still have a couple VMS copies of PASCE.
This is the digital remain of PASCE. They were the first company to migrate to Windows NT system, and rewrote the interface to be truly windows complaint. PDMS has finally done it in version 12. PDS - I have no idea.
ALAMEDA, Calif.--(BUSINESS WIRE)--Nov. 15, 1994--The management of EA Systems Inc. announced Tuesday that a group of its managers and investors who are joining the executive team acquired the PASCE(TM) software business from Digital Equipment Corp.
The new company, which will continue to operate as EA Systems Inc., will be wholly-owned by management and employees.
The company will focus on building its core business of providing software and solutions to the power and process industries for plant life cycle management in a plant's initial design, engineering and construction management phase; and for subsequent operations, maintenance, regulatory and configuration management.
In these application areas, PASCE users uniformly report strong productivity gains, such as reduction in field errors during plant construction to less than one percent and the ability to create more efficient systems for maintenance planning, plant quality management and regulatory compliance. For owner/operators of plants valued at $100 million or more, these systems can significantly reduce operating costs, permitting savings of 25 percent or more of total installed costs throughout the 30-40 year life cycle of the plant.
PASCE Applications
PASCE, an acronym for Plant Applications and Systems for Concurrent Engineering, is one of the leading database-driven plant design and management software products available today. The field-proven suite of applications is distinguished by a common database architecture in its 3D and 2D applications, database integration and intelligent 2D schematic capabilities.
