PDMS Strengths Against PDS 1

PDMS Strengths Against PDS

How many Owner Operators will accept SP3D formats? The fact that SP3D is not established in the market also means that it is not an accepted format by owner operators.

PDMS has the following important technical benefits when compared to PDS :

A highly interactive, 3D, multi-discipline colour shaded design environment

In PDMS everyone has 3D- all the time. Shaded, wire-line- what ever you need to get the job done quickly and right first time. PDS is predominantly wire-line in day-to-day working. PDMS also has a consistent 3D design environment for all disciplines.
The higher level of visualization at the desk top means that it is far easier for designers to understand the current status of design, to work with far higher volumes of data on the screen (covering all engineering disciplines). The result is a higher percentage of right-first-time design­ and fewer quality issues to detect and manage.

One 3D Design environment for all engineering disciplines

Engineering activities take place in a fully multi-disciplinary 3D model (although, of course there are all the access and change controls in place too). Releasing and issuing data between disciplines is only constrained by your engineering work process- not the capabilities of your 3D system.
In PDS, HVAC, Raceway etc are very much separate applications.

Windows .NET user interface

  • Quicker and easier to learn – you can train up new personnel much quicker.
    Faster to use = higher levels of productivity.
  • PDS has not been re-engineered to use the latest and greatest Microsoft technology.
  • SP3D claims to use the latest Microsoft technology- but hasn’t yet emerged as an active production tool.
  • SP3D also appears to be based on some Microsoft technologies which are already being obsolete by Microsoft!

Robust, Flexible Database- Purpose designed for 3D Plant Design

  • Access control is one of the strengths of PDMS. Access control can be setup on specific objects, individual disciplines or parts of the project. With PDS it is much more difficult to limit access to parts of a project for one designer. Most likely every PDS user does have full access to a project, even temps and less trained users.
  • With PDMS you can have as much or as little control as you want. If you want to have automated work-processes where access rights are automatically updated
    as the engineering design of items reaches certain status levels -we can even do
    that too.

Handling of very large  project models

  • The PDMS database has no practical limit in size so the largest projects can and have been handled. However PDS does have a limit. This can be proved if a small model is modeled in both PDMS and PDS and then progressively duplicated many times in both systems.
  • If this process is run back to back then the PDS system will at some stage fail to make the next duplication. This is a way to prove the capability of the PDMS database compared to PDS.
  • PDS forces you to split big projects. That means more admin, more complexity, less flexibility and more dependence on key skills.

Revision Management (3D Model, Layout  drawings, Piping Isometrics  etc)

  • PDMS has extensive, customizable data management tools to ensure available data is always
    fully controlled according to the project procedures and that a full audit trail of changes is available.
    This is achieved with features such as :

    • Full change history
    • Model versioning and status
    • Data Access Control rules (that can be applied down to individual attributes)
    • Change highlighting on deliverables (piping isometrics, layout drawings etc)
    • Rollback of database to any previous configuration. Comparison with data today and any previous state.
  • PDS has none of these features! There is status on an attribute level and that’s it- you can’t compare versions or go back to a previous version.

Copy paste across all disciplines

  • It needs a real PDS expert to copy from old projects. Even then it’s sometimes almost impossible to copy piping elements. This way of working to reduce project start up times is fully supported in PDMS- for everything from design data, to project administration to drawing libraries, to customizations.
  • The ability to quickly extract and re-use data from a pre-existing project is of course a major benefit of PDMS. But we don’t stop there. Why copy data that you need more than once?- why not simply reference it?- so that you can manage and control standard data in a much more efficient and effective way- saving cost and improving quality. With PDMS you can share all or parts of catalogues between any number of projects- and you can make it all work in a multi­ location set-up as well.
