This is part of the daily drudgery of many BIM practitioners:
I am working on a job where the consultants provided DWG and DWF files of their drawings.
So far, so good.
The DWGs are coloured, legible. I navigate around them easily. (exhibit 1);
On the other hand, the DWFs are the black-scale type, thick-black blobs, occasionally intersected by thick-black lines.
Maybe nitpicking, I am amused by this practice.
When I question it, as I often do – I get this kind of response (commonly, not on this particular job):
‘The DWF is the digital (non editable) representation of the contractual document.
The DWG is provided with no responsibility taken for it, just because we are being nice and helpful’.
(i.e. use it at your own peril)
Now, who is kidding whom?
Is the intention to have these two types of files worked on simultaneously?
Am I supposed to constantly check that the coloured one is in-synch with the black one?
If not, than what is the point?
Do they provide them separately to some parties?
Is someone given the coloured only?
How do they know that they are working with contractually up-to-date documents?
Is it just me or can anyone else smell the rat here?
(the point is not that DWFs can be in colour too – the point is that they usually aren’t!)
