I have covered using FBX to access Navisworks data for downstream use. What about KMZ? This format contains lightweight geometry as well as some model structure. It is actually quite difficult to find an easy way to go from KMZ to IFC, or KML to IFC. But, it can be done!

Here’s one method:

  1. Export desired view from Navisworks to KML with “collapse” set to None. This will bring the full model hierarchy with the KML file (see help for more info)
  2. Install ArchiCAD 16 and the Google Earth import / export plugin
  3. File Special – Merge, select the KMZ (this part could take a while)
  4. File Special – IFC 2×3 – Merge to IFC Model…
  5. Select an IFC file (maybe make an empty one to merge with first, like this one)
  6. You will get geometry and some basic data, but the main thing is that the object segregation is still present
  7. From here you can import the IFC file to Revit as usual

Note: you can use 7-zip to extract a KMZ and you will see the KML file inside.

When working with multiple linked files, you can utilize the ability of Revit to close Worksets in Linked Files, and in some cases this is a good visibility shortcut. Along these lines Simon over at BIM42 has written “a few line of code for set up every Scope Box, and Reference plane to the correct workset…”

See the code at:

Managing linked worksets | BIM 42

In Revit 2015, you can use the IfcOpeningElement subcategory of Generic Models (and possibly other categories) for a Linked IFC to hide the orange “void” elements that appear in certain situations, as per this image:

Just use the Revit Links Display Settings to “override” settings in Visibility / Graphics (choose custom, and Model Categories tab also custom) to access this subcategory.

This video shows how Autodesk Vault interacts with Revit server and how to configure them both across different sites connected through a WAN. The demo at the end shows the workflow between different sites.
You will also notice the handling of a referenced DWG in a Revit shared project through Autodesk Vault Professional. The demo shows how and why the combination of Vault and Revit server is the perfect solution for cross-site collaboration.

Tekla have released a viewer app for iOS that can read IFC files. You will probably use Dropbox to get any large IFC files onto your phone or tablet, but you can also open from email or web.

Download at:
https://itunes.apple.com/gb/app/tekla-field3d/id868034113?mt=8

Free version features
• View 3D models in multiple formats: .ifc, .3ds, .obj
• Very large models load in mere seconds, tested to more than 2 GB
• Zoom, pan and rotate 3D models
• Object Outlines and dynamic Shadows to better visualize model geometry and depth
• Open files from email, file-share or web
• Sample files included and more can be downloaded
• Orthogonal view of 3D models – as an alternative to Perspective view
• Imperial units display option for Property values (feet &inches)

Of course, you could also append the IFC to Navisworks, then Glue it, and use the BIM 360 Glue app to do something very similar 🙂

Mehmet Polat Diker has been busy doing some interesting Revit things over at Red Hot BIM. Like this little family that takes two dates and checks if the “deadline” has past or not. Some pretty detailed formulas here – nice work.

Download:
D_GEN_DEADLINE.rfa (Revit 2015)

The deadline family has 2 data entry parameters:
DateA and DateB. Family expects DateA to be earlier than DateB by default.

It has 2 check parameters:
DateAcheck and DateBcheck. These parameters show how the family interprets the dates we’ve entered.
