Hi there,

If you want to contact me direct by email go to my Duncan Lithgow contact page. Otherwise leave me a note on my talk page.

My name is Duncan, born 1974, white (Scottish and German descent) male New Zealander living in Denmark. I work in the building industry employed on a major hospital project[1]. At the moment my contributions are mainly on articles about CAD and BIM.

Much more about me at LinkedIn --duncan.lithgow (talk) 20:15, 17 May 2012 (UTC)

Good sources for info on CAD industry[edit]

Info to add to CAD pages[edit]

I was just looking for this to send to a colleague who has started with the Family Editor... The 7th stage should be "You are able to explain to those who have not yet achieved enlightenment how revit actually works!"

It usually goes like this: "Theres this thing here that does this. And over there is another thing, called something very similar, that does something totally different. Now if you poke one of them in this way and pull the other like this you can make these other objects, which exist only in the nth dimension of nested families, do what you want". "Errr...ok. I tried doing what you said and I just got an error." "Hmmm... Just let me divine the problem from these random symbols and the current position of the planets.... Ah yes, you failed to uncheck the tickbox of unintended consequences which is concealed in the dusty basement of non descriptive option names.....havent you learned anything yet???"

BIM Collaboration Format[edit]

The BIM Collaboration Format (BCF) is a structured file in XML which defines comments attached to elements in an Industry Foundation Class (IFC) Building Information Model (BIM)[1]. This allows developers of BIM supporting software to design interfaces for collaboration between users who access the same model, especially with different software.

The format was developed by Tekla and Solibri and later adopted as a standard by buildingSmart. Notable software with native support for BCF are Solibri, Tekla, ... Plugins provide usability for software such as Autodesk Revit, Autodesk Navisworks ...
