Improving your Navisworks Skills (book and other updates)

Luke Johnson

I am loving Navisworks more with every passing day.  A job doesn’t have to be a fully collaborative / coordinated project in order to get benefit from Navis.  Here is a collection of recent information and resources relating to Navisworks.  Hope you find something interesting!

Firstly, a link to the Navisworks updates page.

On Revit – Navisworks implementation generally:
“… contractor will import the Revit model into Navisworks and use Navisworks to ‘virtually construct the building’, creating construction sequences to ensure every element slots into place, almost like a jigsaw. Linking the model to packages like Microsoft project will allow digital construction monitoring against the project schedule. This is happening all over the world…”

Up and Running with Autodesk Navisworks 2014
by Deepak Maini

I have been reviewing this book and I really enjoy its content.  It is detailed, comprehensive and easy-to-follow.  Highly recommended for those who are learning Navisworks or those who want to increase their proficiency and efficiency when using Navisworks… More on this book in a future post.

4D IFC Importer for Navisworks Manage 2014
At this point in time, you can’t create products in Navisworks from the API, but if you import the IFC using the native importer (IFC2x3 only), then you can run my IFC enhancer (plugin can be downloaded from http://www.geometrygym.com/downloads ) which can generate the timeliner tasks and identify the ifc products by their unique identifiers.
Download:
ggNavisIFC2014x64 v0.0.02.msi (18th October 2013) Navisworks 2014
New plugin to extract 4d information from IFC files and convert into Navisworks timeliner.

Three becomes Four – Ways to go from Grasshopper to Revit

I previously posted about Three Ways to go from Grasshopper to Revit.  However, Vasari Talk 18 (uploaded by AutodeskBuilding) shows that there are at least 4.

Three Ways to go from Grasshopper to Revit

Luke Johnson

It seems that more and more people are trying to move intelligent data from Grasshopper to Revit.  There are at least 3 different ways to do this:

Have you tried all three?  Which worked best for you?

Rhino to Revit with Hummingbird | WhiteFeetTools

A recent and very informative post from LMNts describes their experience in moving data from Grasshopper to Revit.  Here is just one paragraph:
Chameleon appeared a few months ago and has proven to be an effective tool for adaptive components. The interface is intuitive on both the GH and Revit sides and we are yet to find any serious bugs with it. Another recent plugin is named Hummingbird (keep track of all these animals), a similar program which accesses the WhiteFeet Modeler to import adaptive components as well as Revit primitives (this has a lot of potential and will be discussed more in a future post). Take your pick, these are both great plugins.

Chameleon – Grasshopper and Revit interop plugin

Luke Johnson

A lot of you may have heard about it already, but if you haven’t:
Chameleon is a plugin for both Grasshopper and Revit with a focus on interoperability, simulation, and efficient practice workflows. Chameleon’s main advantage is its ability to facilitate easy transfer of geometric data between Grasshopper and Autodesk Revit, but also includes other valuable tools to make life easier, both in Grasshopper and Revit.

This latest version includes upgraded the functionality of the Curtain Grid management tools for Revit users. These tools now allow control of curtain panels in addition to the grids and mullions. There is also a preview to show the results of changes before accepting.

Adaptive Components from Grasshopper to Revit via IFC – it CAN be done!

Luke Johnson

Now here is something cool – Jon Mirtschin of Geometry Gym has been working on an IFC importer add-in for Revit (my previous post here) (current version 0.0.23 download direct here, or source page here).

What made me go ‘wow’ today was this: using this add-in, you can take an IFC file and import it as a Generic Model Adaptive Component in Revit 2012.  You can select the points and adjust it just like ANY Adaptive Component – but it came from Grasshopper via IFC!

Here is how to do it:

  1. Download and install the add-in
  2. Upon opening Revit 2012, you can see the add-in under External Tools – Geometry Gym IFC Importer
  3. You will need to email Jon to get a license XML file.  Paste that into the appropriate folder.
  4. Now, run the Geometry Gym IFC Importer again.
  5. Download, then select the IFC file that Jon provided today (see below)
  6. Click ‘Proceed’ then wait a bit
  7. The IFC will now appear as a bunch of Adaptive Component instances that you can select and modify!

Here’s the Grasshopper model, and here’s the IFC file.

In fact, there is some serious 3rd party development happening on the Grasshopper to Revit front – check out:

Something Revit 2012 can do better than 2013 (at the moment) is…

Luke Johnson

importing IFC2x4.  Thanks to Geometry Gym, and Jon Mirtschin in particular, an IFC importer add-on for Revit 2012 is under development that aims to support IFC2x4 with nurbs profile / perimeter exchange.

Jon says:
I’m developing the Revit addon to import these files as the functionality is not available in the native importers. I haven’t built for Revit 2013 yet, but if you have Revit 2012 and want to try, the installer is available from http://www.geometrygym.com/downloads

Note, Revit 2012 64 bit Addon to import IFC files.
This is an early public release for initial feedback and comment. Addon undergoing rapid development. Please use with care and send suggestions and observations.

Here is an excerpt showing how IFC2X4 RC2 improves geometry capability:

Geometry
Additional entities are added to the geometry resources. (1) The definition of manifold boundary representation has been enhanced to include advanced B-reps, based on NURBS. Therefore b-spline surfaces and b-spline curves are added. (2) The curve bounded surface based on bounding p-curves (curves defined in the parametric space of a surface) is added to allow any surface to be bound; it was restricted to only planar surfaces before. (3) Tapered solid of extrusion and tapered solid of revolution are now included to define simple taper, restricted to one section and to topological similarity of the start and end profile. (4) A fixed reference swept area solid is added to define an advance sweep along a directrix with a fixed orientation of the profile. The swept disk solid has been simplified by implicit start and end points on the directrix. (5) Elementary surfaces have been enhanced by incorporation or cylindrical surfaces.
