Revit Groups – Powerful when used correctly, Painful when used carelessly

Luke Johnson

A great way to test if you know What Revit Wants is to try and run a complicated high rise or health facility using model groups. The principle and general functionality of groups is fine, but they can get very difficult to manage if not treated properly. However, they can be mastered.

As Ceilidh Higgins puts it:
Whilst groups are error prone and seem to have a lot of bugs … they are still the best available solution within revit for collecting together repetitive sets of objects. 

She recently presented at RTC on this subject, and she has provided the associated presentation slides for download and viewing.

Adding globally available Aster GDEM Topography to Infraworks (and Infraworks Interference Checking using Drive)

Luke Johnson

The release of the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Global Digital Elevation Model Version 2 (GDEM V2) was announced on October 17, 2011. This data can be downloaded and imported to Infraworks.

Here’s how:
1) Go here:
http://gdex.cr.usgs.gov/gdex/

2) Create an account / login

3) Browse the world, then Select a region using one of the tools, such as Rectangle

4) Download using ArcASCII

5) Back in Infraworks: Import from file, Raster

6) Select the ArcASCII file

7) Right click the source in Infraworks and pick Refresh. Your topo should now be visible:

 8) Now import your Revit or Civil3D models and create your animations…

"Manipulating IFC sub-models in Collaborative Environments"

Luke Johnson

This 2007 research paper by Dr M M Nour gives an overview of IFC and some of the challenges of using it in a collaborative BIM environment. It posits a potential solutions that it calls FIOPE. It also considers IFC model splitting and segregation, and how to handle comparison and IFC file differences.

A few quotes:
“This paper addresses the problem of workflow management in collaborative teamwork environments, where multidisciplinary actors and software applications are involved. Design versions or variants may represent different development stages, partial designs or solution alternatives that need to be integrated together. The paper presents a novel approach to splitting and merging IFC sub-models (partial models) at different degrees of granularity away from the schema oriented approaches. It relies on an instance oriented approach (FIOPE) Flexible Instance Oriented Partial Exchange Environment…”
“…in order to achieve a lossless information exchange among AEC/FM project members, either the software developers should change their internal data structuring to eliminate irrelevant IFC data loss or the exchange should be limited to partial models that contain application-relevant IFC data. The latter seems to be the most practical solution…”

Want a powerful new way to visualize your Revit models based on parameters? Its called ColorByNumber :)

Luke Johnson

This is one of the most exciting new addins to appear for visualizing your Revit model. It is simple to use, powerful and intuitive, and I recommend you try it out.

Follow these steps after clicking the above link:
1) Scroll down to ColorByNumber trial and add to cart

 
2) Checkout

 3) Place Order

 4) Download file

5) Install the file and open Revit

6) Click on the Color button on the Addins ribbon

7) Put in your email and the license key that you were emailed during checkout process

Here is a quick how-to on using it:

  1. Open a 3D View and open ColorByNumber
  2. Switch to the Colors tab and click on the New icon. This will make a new Colour Scheme. 
  3. Give the new scheme a name.
  4. Select a Category and a Parameter
  5. A list of all available values in the project will appear, with some preset colours
  6. Click Apply

These colours are now applied to your view. The colours will be visible in all display modes in 2014: Wireframe, Hidden Line, Shaded, Consistent Colors, Realistic and even Raytrace. Its easy, functional and overall very impressive…

Switching to the Schemes tab will now show this new scheme as an option. If we switch to a completely different Revit project, we can instantly re-use this scheme in the other project. We don’t have to transfer the scheme or anything.

Just when you were thinking how great this all is, there is a humble little button at the bottom of the main ColorByNumber dialog – Isolate. This will isolate the coloured objects, making it very easy to navigation and view your Revit model based on Category, Parameters and values.

Let’s try another example: colour all Walls by their Structural Material. In about 8 clicks, it is done.

So, who is Greg Demchak, you may be wondering? Well, he was this guy:

so you can see why he knows a thing or two about Revit and UI design 🙂

Some dot points:

  • A schedule is a good tabular view of the model data… With ColorByNumber, we make accessing information easy and visual, which can lead you to new insights on your model
  • quickly select and isolate elements by their parameter values–something you can’t do with Revit out of the box. 
  • user research found that ColorByNumber is on the order of 100 times faster than using built-in Revit tools that accomplish similar results.

    Try out Autodesk 360 Viewer

    Luke Johnson
    1. You can access and join the tech preview here
    2. Login with your Autodesk account
    3. Accept terms and conditions (notice that Fusion is mentioned here…)
    4. Go to your email and click on the confirmation link
    5. You will also get an email with a myhub link
    6. Create a Project
    7. Click Upload
    8. If the file is something that Autodesk 360 Viewer can handle, just go to Data and then click on the uploaded files thumbnail – the viewer should load

    I tried uploading a Revit file and it was very smooth to navigate. You can click on the toolbar at the bottom and show model structure (3 squares in a tree view), or click on the gears and turn on the ViewCube.

    Just for the fun of it, I uploaded and viewed this model:

    With features for team communication and wiki, it is obvious that Autodesk 360 intends to be more than just a file sharing and viewing tool.
