SIM

No, this acronym I am referring to is not for the card variety you need in your mobile device. In the context of this post, it stands for System Information Modelling.

Conventional “Intelligent” CAD tool comparison

Back in November 2010 I wrote an article for the Electricity + Control magazine about Data Centric CAD. In this article I compared 5 different CAD (Computer Aided Design) systems with one another to try and establish which software would be best to use in a certain application. At that time, I could not say that one system ticked all the 12 boxes in terms of good administration, drawing/graphics capabilities, simple data entry methods, exporting information, adequate hook-ups presentation, handling field-bus systems, simplifying data sheets, doing calculations, enabling document control, calibration and maintenance features, interfacing with other packages or any other special functionalities. I have never heard of the a SIM system or its implementation back then.

In 2013 I heard about the SIM concept which is refreshingly different. Information is entered once only. If you are like me, getting frustrated by repeating tasks like copy and paste, checking and re-checking different drawings when changes are made, you must definitely read on. In SIM, generated objects exist only in one place. They are not placed rigidly on a drawing but rather exist in the virtual space of the database so that only the parts of interest can be called up when required. They can be placed anywhere on a work-space drawing and all relating data will show up as needed. This concept is not only advantageous to the designer and checker, bit ideal in the real life cycle of an installation where changes have to be made on the fly and recorded on the model at the same time.

The DAD package from I&E Systems in Australia is such a revolutionary system. That is why I was really delighted when Rob Gillespie phoned me from Perth last week to assist him with another demonstration to a South African client in the near future. Being involved in projects for 25 years from shop floor in the end user’s shoes, right up to package engineer for an EPCM, I can fully appreciate the advantage the SIM package can deliver.
