My last blog on CAD drawings and BIM returned some interesting comments from within my blog as well as from Linkedin Groups. It appears some were missing the point or not understanding it while some responses were building upon it. As a means to clarify my point I would like to take this discussion to the next level.
For the purpose of this blog, let’s consider the BIM data as representations of the manufacturer’s product data. In order for building manufacturers to be competitive they will most definitely have to be concerned with the BIM representation of their product data. But that is not all they are concerned with as they have the manufacturer’s representation of that data, not to mention marketing data such as cut sheets, shop drawings, etc.
- Manufacturers Representations – There are a number of categories relating to data from the perspective within manufacturers’ walls but let’s just look at a few items:
- Engineering data comes in all sorts of different methodology such as solid modeling, database driven and plain old 2D. This data is the life blood of the manufacturer, not only displaying current product line but being used to create new product (R&D). Actually, when I talk to manufacturers I like to draw a big circle and label it as the engine model from which everything is a derivative of this data.
- Marketing data – Even though there are and can be more derivatives than just marketing data from an engine model, for this blog let’s look at the marketing data as data including BIM data and cut sheets or shop drawings.
- BIM data is from a geometry point of view and should, for the most part, focus on providing the ‘foot print’ and ‘volume in space’ for the product. There are other concerns involving more detail that I will leave for another blog. The BIM data from the meta data perspective is also a key factor as it is really where manufacturers have to be cognizant in order to provide all the data necessary for their product, which includes pointers to cut sheets or shop drawings and specifications to name a few.
What I was trying to convey in my l last blog was that manufacturers will need to continue providing drawings of their products in a 2D fashion. This data will most likely take the form of a PDF file which will continue to provide the necessary detail and information that an architect or engineer needs. Again, this is something the BIM models do not provide other than by including a URL link to this data.
There are quite a few other derivatives we could talk about but the main point I want to emphasize is that all of the product data could be taken from the engine model, which is exactly what we are doing with the FAR Process - becoming a derivative of the engine model.
