Experienced Navisworks Coordinators typically have a very solid workflow in place for grouping clashes into clash groups. Some prefer to do that part manually (with selection and filters), so they can observe and determine which items should be grouped together. Others will use an auto-grouping tool, like bim42 Group Clashes, or iConstruct.

If you are using iConstruct and you wish to use the Navisworks clash group data downstream, you may wish to preserve existing clash groups at each subsequent clash run, and only group the ‘new ungrouped’ clashes. The bim42 Group Clashes tool has a tickbox for this, and iConstruct 2019 provides a filter. If you are using iConstruct 2018 or older, you may be wondering how to preserve existing clash groups and only “push” the grouping rules for clashes that are currently not grouped.

 

Here’s how:

  1. Run the Clash Manager from iConstruct
  2. Find the list entry without a name
  3. Versions:
    • iConstruct 2019 has a filter for “Show Ungrouped Clashes”
    • iConstruct 2018 – select only the ‘unnamed’ Clash Group: ,
  4. Then click “Create Clash Detective Group”
  5. iConstruct will immediately create the relevant groups from only the ungrouped clashes
  6. You can then go ahead and Sync to Revizto, or use the data downstream in some other workflow

 

Here’s a video from Robert Gadbaw that clearly demonstrates this workflow:

This workflow will allow you to use iConstruct to group your clashes, and preserve those groups when Syncing with Revizto. Revizto has a very solid and customisable connection to Navisworks that includes the ability to sync the clash results with Revizto Issues in both directions.

The first point release of Revit 2019 is now available… Let the deployments begin. Your projects are now running out of excuses as to why they shouldn’t upgrade 🙂

Here are some direct links to the Revit and Navisworks update files.

Update: From Purvi Irwin on Twitter:

In the new homepage for #Revit 2019.1 when you hover over a recent project, you get the path of the central, your local, and the file size! If it’s not workshared, then you get the filepath and size. Pretty sweet.

Interesting little release by Dimitar Venkov on Github a few months ago. It is essentially a Python shell for Navisworks 2016. You install by unzipping as per instructions below. You may have heard about RevitPythonShell, but obviously this one is for Navis.

To install, simply extract the zip archive in the below folder:

%APPDATA%\Autodesk Navisworks Manage 2016\Plugins

Downloads

You can read more about the features at the main page here.

  • interactive IronPython interpreter for exploring the API
    • with syntax highlighting and autocompletion (in the console only)
    • based on the IronLab project
  • batteries included! (Python standard library is bundled as a resource in the RpsRuntime.dll)
  • full access to the .NET framework and the Navis API
  • configurable “environment” variables that can be used in your scripts
  • save “external scripts” for reuse and start collecting your awesome hacks!
  • run scripts at Navisworks startup

And some example/s are in a GitHub folder:

If you have a Navisworks crashing or Navisworks not starting up problem, you might try resetting Navisworks settings.

Here’s how:

  1. Open Windows Explorer
  2. Type %appdata% in the address bar
  3. Rename the relevant Navisworks folder here with a .bak extension
  4. Start Navisworks

Note: You can actually get to the options from the start menu, even if Navis won’t launch…

 

There are other places that Navis may stash some settings. You may also want to check out:

Here is a few quick tips that I had sitting in draft post:

  • To delete lots of views quickly, select and then press Delete key. Do not try to right-click.
  • To combine multiple Clash Groups in the Clash Detective, select the groups, Ungroup (sub-clashes will be selected by default), then Re-group..
  • To delete multiple empty clash groups, drag a clash into one of them. Then, Select All the Groups and you can Explode Group
  • If you Append an NWD, the views with saved Hide/Required and Material Overrides will import “correctly” with these settings (but a Viewpoints XML cannot import these element hide and colour settings)
  •  Use Properties+ … it is simply the fastest way to test and build Search Sets

This recent post on Dynamo Nodes shows how a simple Navisworks Search Set can be built by Dynamo running inside of Revit:
Create Navisworks Search Set XML for Element Ids | Dynamo Nodes

In the first release, this node just uses Element Ids to build a long ‘orsearch set, but this basic idea could easily be extended and adapted to more closely connect Revit to Navisworks search workflows through Dynamo.
