Why Viewing BIM After Dark will be Worth It for You

Luke Johnson

I’m honest enough to admit that Revit has the unfortunate reputation as a tool that is “bad” for presentation. Happily, BIM After Dark aims to correct that – by making all of us better at using Revit for a variety of presentation tasks.

BIM After Dark is essentially a training video series prepared by Jeffrey A Pinheiro, who many of you know as the author of the excellent, long-standing Revit blog The Revit Kid!

I had the opportunity to preview this video series prior to its release, and I must say I am impressed. Firstly, I’m sure you all realise that as good as Revit is, we still need to use other tools for certain presentation tasks, the foremost being Photoshop. It’s great that Jeff covers the effective use of Photoshop in considerable detail, and provides task-specific and industry-specific tips that will give you a real head start over the competition. Jeff covers some truly advanced, unique methods, and at the same time he includes some basic stuff that will help you if you are just starting out with Revit.

The plethora of included content and samples are also of very high quality, so if you can get access to them, I recommend that you do so.   It includes texture, background and entourage images, Revit library files and some Photoshop PSD files too.

Here are some examples of the tips and workflows covered in this series:

  • how to override the Shaded representation of RPC trees
  • 70 50 20 method for shadows (I guess the old 10 6 10 is superseded now) 
  • overlay method in Photoshop for images, such as section perspectives (“multiply”)
  • comparing 2am rendering quality for local vs cloud
  • “core” method for quick interior context
  • panel sized bump mapping for realistic glass
  • “screen” layer overlay for lighting rays (combine with various blurs to increase effect)
  • cgtextures and gobotree
  • using the burn tool for ambient occlusion of entourage

These are just a few reasons why you should check out this new series.  If you are serious about using Revit for presentation, BIM After Dark will definitely be worth it for you.

A few thoughts I had while viewing the series

  • the autoclicker tool could be launched using the script launching method I describe here
  • Jeff mentions he doesn’t quite understand something that happened with site cut pattern – this was because the extra bit of the puzzle is the “poche” setting in Site Settings 
  • you can right click on the ViewCube to quickly align a 3D Persective view to a normal Section view

SAuBIM Room Calculation Utility – links and tips

Luke Johnson

Do you ever get a little annoyed by the things Revit doesnt let you do?  There are some irritating limitations in our favourite BIM program – but SAuBIM aims to workaround one of them.

Out-of-the-box Revit does not let you use a ‘calculated parameter’ in a Tag.  Don’t ask me why.  It is just a fact of life at the moment.  SAuBIM (pronounced saw-bim, and meaning ‘semi-automatic BIM’) takes the pain out of this with regard to one specific task – calculating room occupancy data and then displaying it in a tag.

Basically, you take the following steps to use SAuBIM:

  1. Close your Revit project.
  2. Install and register SAuBIM.
  3. Open the SAuBIM utility.
  4. Set your Revit ‘Program’ location in the top Browse box.
  5. In the middle Browse box, select the Revit file that you want to calculate Room Occupancy for.
  6. Click ‘Import Schedules and Tag’.  Wait for Revit to do its thing.

    TIP 1 – If you come across a dialog that says ‘Enter Interactive Mode‘, then something hasn’t quite worked properly.  I recommend that you:

    – Close Revit WITHOUT saving
    – Follow the steps above again, but between steps 5 and 6, tick the ‘I am Importing into a Revit Template File ( *.rte) box.  Even though you are using your .rvt project file, this step may actually cause SAuBIM to complete the import correctly.

    TIP 2 – If the above also does not work, you can manually complete the following steps (on your project BEFORE applying any SAuBIM items):

    – Copy (from Project Browser) the 2 x schedules from
    “C:Program Files (x86)SAuBIMSAuBIM InstallTest Project – Code Calc.rvt” (for Windows 7 64 bit)
    and Paste (Ctrl+V) them into your project
    – Load the Room Tag from
    “C:Program Files (x86)SAuBIMSAuBIM InstallRoom Tag – OL.rfa” (for Windows 7 64 bit)

  7. Once you have saw-bimmed your file, you can now use the Update Occupancy Data function (Revit must be closed to do this)
  8. Tag your rooms with the Room Tag – OL.rfa tag.

You have to keep in mind that it is semi-automatic – you need to ‘Update…’ the data before plotting / exporting.

However, it is a good proof-of-concept, and will prove extremely useful to some architects.  Thanks SAuBIM!

Now, here is a little request / challenge to the SAuBIM guys:  What if you ‘exposed’ some of the functionality of this program, and made it more customizable?  
This is what I’m thinking:  you allow us to select Calculated Parameters FROM a specific project file, and then use your tricks to push these into Shared Parameters, which we can then Tag?
I think it would be pretty easy, with the functionality you already have in place?
