There are No LODs

Luke Johnson

I tweeted this today and I thought it was worth a repost here for all the Facebook and LinkedIn followers…

There are no LODs.

There are only:

  • Design Models,
  • Construction Models, and
  • Operations Models

What does the above statement mean?

Firstly, that if you are going to try and standardise something you need to make it simple and practical. Secondly, the content of a BIM dataset is best described by its current purpose. It won’t always be a Design model. Once it starts to become a Construction Model, the Design Model needs to die or be used only for crude reference. And once it becomes an Operations Model, it may need some extra data added, but it will likely need a lot of Design and Construction junk removed.

Don’t try and make a model that lasts forever, for every purpose, and then attempt to standardise that as a point-in-time deliverable with some ridiculous metrics.

Make the BIM standards simple, practical, and closely tied to the current purpose of the model.

Major BIM Codes, Standards and Reports in one place?

Luke Johnson

There have been various attempts over the years to create a true BIM portal, with links to all relevant documentation.  Have you checked out CODEBIM?  The reports page is pretty impressive list of BIM documents …

Free training resources released by Autodesk under Creative Commons

Luke Johnson

There is apparently over “20000 pages of documentation” that will be released, along with videos and 3D asset files.

It could be interesting to see how this release intersects with the development of Revit standards and Revit content globally…

The Autodesk Creative Commons “Area”:
AREA | creativecommons

“The group adopted the Creative Commons licensing which means 20,000 pages of documentation, 70 videos and 140 downloadable 3D asset files are now ready to be modified, remixed and shared globally.”

via / heads-up:
Autodesk makes huge trove of docs, training materials and 3D asset files available under Creative Commons – Boing Boing

As per the above Autodesk page, “More content to come soon…”

Dutch Revit Standards for download

Luke Johnson

Dutch Revit standard (template) for download:

Download – RevitGG.nl
Translated version

There is a link to download version 0.8 from Dropbox at this page.

The download includes content like:

  • project template
  • families
  • family templates
  • materials
  • resource files (CAD import / export maps, Shared Parameters and more)

Happily, these standards are Creative Commons licensed.

BIM Documents and Standards – big list for download

Luke Johnson

I can’t recall how many BIM document PDFs I have downloaded over the years.  There are web indexes of the indexes of the lists of standards you can access…

But here is a simple list by Ben Malone:
https://docs.google.com/folder/d/0BwLLFYLrgVI6WldMeFlDQ1hSVE0/edit?pli=1

It looks like it might be a work in progress – there are still plenty more that could be added (and probably will be, when Ben finds the time 🙂

Note – if you click the “Open in Drive” button, you can then check all the boxes and click Download to get them all at once…

Heads-up from Dave Light:
Revit: BIM Docs!

BIM Standards for download

Luke Johnson

The sheer volume of different BIM standards can be confusing in itself – and that is without even considering the  
a) usefulness, 
b) applicability, 
c) practicality or 
d) up-to-date-ness 
of these different standards

In any case, a recent and decent list has been started at:
CAD addict: List of Existing BIM Standards

Some other useful links / lists:
Weblinks (big list of Standards on natspec.org)
BIM Standard and BIM Example Drawings Sharing (forum thread)
BIM Libraries | Whole Building Design Guide
BIM/IPD Aus (standards and guidelines with Australian focus)

Transfer Color Schemes using Transfer Project Standards

Luke Johnson

in a project where you want to inherit the properties panel in the “Manage” choose “a color designation schemes,” and in the “Deselect” target checkbox only “color scheme designations.”

Family Creation, Performance and Standards post – with tips (BIMAdvent)

Luke Johnson

There is huge post on content (family) creation over at this link.  I have provided a few useful excerpts below:

A handy list of relevant Agencies / Organizations:

Nice tip on formulaic materials:
How do you parametrically change a material parameter in a family if the material itself depends on factors outside of each type designation? After all, it’s impossible to control materials through formulas. Our approach (when the number of ‘stacked’ geometry instances is few) is to model separate pieces of geometry, apply their unique material and then control their on/off visibility through parameters.

How to provide error messages to the family user:
One solution to this perplexing problem is to include 3D text displaying a message to the user when a non-existent configuration is selected.
