BIM standards

CAD ​​Addict has published a collection of BIM standards in different cities and countries. In Spain, that I have heard, there are none but my faith is that soon someone posts one. I leave the list published in

Contry Wide:

  • Finland: Common BIM Requirements 2012(published March 2012)
  • United Kingdom: AEC (UK) BIM Protocol v2.0 (published September 2012)
  • Australia: National Guidelines for Digital Modelling
  • United States: National BIM Standard – Version 2 (Published May 2012) (need to login to access the PDF)
  • Singapore: Singapore BIM Guide

Other Public and Local Administrations:

Higher Education Institutions:

Architects’ Boards and Associations:

The same way as CAD Addict I ​​encourage you to tell us if you find any other standard. I hope this compilation will be usefull to develop a Spanish BIM Standard.

Checking the transmittance of the walls

Despite preconceived confidence when working with Autodesk software, is good from time to time make some little comparison exercise software to see if you have similar values. In this case, related to the calculation of thermal loads, I wanted to see if the transmittance of the walls which facilitates the Autodesk wiki with documents, is the same with Design Builder.

The Wall is the chosen “standard wall construction B”


I created the same wall with Design Builder:


The comparative results are almost identical, as is obtained with Revit 0.2993 W (m² x º K) and 0.300 W Design one (m² x K).

Forcing Yes/No parameter with If formula

[Google translate]

I could say that is a great find but the truth is that the information that follows is a derivation of other articles published on other blogs, wiki’s or websites.

Sometimes we are forced to use parameters of type Yes / No in creating Revit families is MEP, Architecture or Structure and control of this parameter via a formula is not entirely intuitive.

When we are in the situation of having to force the value of this parameter to True or False using a formula first tried putting a “= 1” or “= true” for true and “= 0” or “= false” to false but this does not work. There are several sites where they explain that these parameters obey the logic formulas as 1> 2 then this value will be True or 1 = 0 for a false value. The site that I like is the for examples of using these formulas, the like has practical examples and moreover is the Autodesk WikiHelp introduces us to the formulas available but with few examples.

In this article we take the opportunity to show you how to make a control parameter forcing parameter value Yes / No If with formulas and logical relationships.
