I’ve recently had the chance to put the new Lumion 9 through it’s paces.

Why Lumion

At Virtual Built Technology amongst the many BIM services we offer, we also create construction visualisations and animations.

Virtual Built Construction Animations

This video is a mashup of various Construction Animations we’ve done over time. Contact us for more information: virtualbuilt.com.au

A Demo Reel / Mashup of some recent work…

Over the years we’ve played with many software solutions to get the kind of results our clients are after. Each time we do this kind of work it’s slightly different, either a client will require something different, there’s all sorts of budgets, a client might want to focus on a specific area, and what we can get our hands on in terms of models etc, is always different. In the past we’d model in Revit and Sketchup, federate and visualise in Navisworks or 3DS Max, animate in Navisworks or 3DS Max and then post production in iMovie or Motion and Final Cut. A complex high end animation, might see us jump in and out of several different applications several times over before completion.

However, since Lumion has come along, we’ve been able to significantly increase our output by simplifying the often many different steps we’d need to take. And whilst it isn’t quite a one stop shop, it is definitely made life a lot easier.

How we use Lumion

Firstly we define the clients requirements. Is it just images, or is it an animation? Then we define what are we trying to show in the images or the animation –  Is it the different stages of construction, the site setup, the greater site context (say a busy city street), the architectural finish? The animation might become more complex if there’s something specific that the client wants to demonstrate in detail (say safety, traffic, or a lifting sequence) In this case, we’re not just rigging up a camera, we might also be keying and animating objects.

Lumion is more then capable of all of the above, but more importantly it’s able to do it all with ease. The software is intuitive and simple. And since this type of work is very susceptible to ‘scope creep’, and client whims, this kind of simplicity and ease adds up to hours and hours of time saved.

Building a model (a typical example)

We primarily use Revit for developing a lot of our initial model content. Often we’re able to get our hands on the consultants models (or we build up our own), then we add some context like neighbouring buildings, streets, pathways etc. (Lumion can also do this with OpenStreetMap data) Then we add other content like cranes, concrete pumps, people, fences etc. This particular part requires some thought, because there’s a couple of ways we can arrive at the end result. Firstly Lumion provides a lot of really good content (People, cars, trees, cats, etc) and we can add this in Lumion (saving a few steps in the process), however, there isn’t a lot of “Construction” content or the right content, so we often need to get that elsewhere. Sketchup Warehouse is an example of a good source. Getting content from Sketchup Warehouse, we can either bring it directly into Lumion, or go via Revit into Lumion.

Back in Revit however, we can utilise the LiveSync option to quickly generate content and see it populating Lumion. I’ve created a tutorial of the LiveSync tool below.

Lumion Live Sync

This video is about Lumion Live Sync

In the more complex projects, we will use many 3D views to export different ‘scenes’ to Lumion. With each 3D view’s content being controlled by Worksets or Phases. Lumion has layer control (20 max) that can control the visibility of content. So, the different views in Revit might then correspond with different layers in Lumion.

The layer manager is pretty limited however, and one area Lumion could improve on.

Lumion Layer Manager

Lumion also has a feature called Variation Control that allows another layer of management to model variations

This particular feature is great for different phases of the same model. (ie construction phasing) You bring this feature into play particularly when you’re animating a sequence where you want a model to change over time. It is limited a little in its fine tune control, for example you cannot “fade” the different phases in, it’s just one at a time.

Images and Animations

Once my model is sufficiently built up and materials applied we can now begin composing images and animations. Lumion provides three different outputs. Photo, Movie, and feature called 360 Panorama.

Photo

In the Photo tool, you simply navigate your viewing window to a desired location and Store the camera. Then it’s simply a matter of adding a Style or adding various effects. Then hit Render and you’re done… It’s really that simple!

The camera location and Effect is stored, so, as you change your content (at your clients whims) you can very quickly fire off an updated rendering that reflects the changes.

Movie

I’ve created a tutorial on how to create an animation in Lumion.

360 Panorama

This tool is great and is something we’re doing more of. It provides something that is a more interactive.

Here’s an example of how it can be used

Summary

Lumion is a certainly a fixture in our animation and image rendering workflow. It’s a great tool that has significantly increased our speed and output.

Because the visualisation is so good even in the building/editing environment, we’ve been using it live in client presentations and meetings.

A great product.

What technology stack should you use when managing and collaborating on a significant and complicated design-build infrastructure project?

Stantec recently shared their workflow on their Ideas website – and it has Revizto right in the middle of it.

Here are a few quotes to get you started:

“The team decided to implement Revizto early in the design phase. It’s an easy-to-use, secure, file-neutral, cloud-based, model-review solution. Model files were published to Revizto, unattended, every night. Each day, the design-build team and Sound Transit could visualize the current design in all areas of the facility. We saw a vast improvement in collaboration and engagement because the model was accessible to anyone, from anywhere, at any time.

Revizto’s issue tracker became a one-stop shop for model-issue and clash management. Typically, a team might use Revitzo to coordinate a single building model. But our team took that a step further by using it for the entire site—multiple buildings, the site, the tracks, and the underground utilities.

This is a process we intend to implement across our suite of transit projects going forward, changing the way we do work by building it into our mindset from the start. By using Revitzo at the very early stages of design, we were able to facilitate a level of teamwork and collaboration that was instrumental in helping us to meet deadlines, stay on track, and stay in lock-step as a project team.

the ability to visualize and identify issues early and across the entire facility saves thousands of dollars in change orders and construction delays.”

It is extremely easy to reduce the size of a point cloud dataset using Recap. “Decimation” is the process of discarding points from the data to improve performance and reduce disk usage.

With the release of point cloud support in Revizto, you can now bring a point cloud into the Revizto platform in a number of ways:

  • Export from Navisworks
  • Export from Revit
  • Import points directly in RCP or RCS format

Once the reality capture model has been added to Revizto, you sync it to the cloud. From there, you can download and view the point cloud on your iPad, and of course you can start creating issues that relate to the captured condition on site. You can even overlay 2D drawings onto the reality capture data.

The decimation process is very easy :

  1. Open your Recap file (add scans and index first if necessary)
  2. Click Export
  3. Give your file a name

  4. Click the settings button
  5. Move the slider to adjust your point decimation – you might use around 50mm decimation for a lot of site applications.

  6. Save the file

There are other considerations, such as:

  • How can you set up coordinate systems to work with Revit, Navisworks and Revizto?

These will be considered in more detail in another post.

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.

We have been using HoloBuilder to capture as-built conditions on a huge hospital project, in order to maintain the federated BIM dataset (BIM to FM / Asset Information Management). 360 photos are a very quick and easy way to capture the context of building elements, but not their geometry.

 

This tip comes from one of our local HoloBuilder experts, Lisa Verschoor:

How to move across an updated drawing/sheet in HoloBuilder and have the already existing waypoints attached to the earlier version carry over automatically

    • Open HoloBuilder
    • Select sheet you want to replace (in example pic below I’m replacing sheet 020-H-003)
    • Click on the “Exchange this sheet” button (two opposing arrows)

 

    • Prompt will ask “Do you really want to replace the current Sheet with a new one?”
    • Click Ok
    • Now drag and drop updated sheet
    • Select High Res option
    • Ok
    • All done! 🙂

You may have noticed that Revizto notifications now provide a direct link to Open that issue in Revizto. This special hyperlink will prompt to open Revizto, and it will jump to the correct issue in the Issue Tracker.

The special link is made of a few parts, notice the project number and issue ID in bold below:

https://api.sydney.revizto.com/v4/region/redirect?url=revizto%3A//viewer/50789/issue_tracker/44

Using the predictable syntax above, you can use your own Revizto regional server, project number and issue ID to create these hyperlinks yourself, either in Excel or programmatically.

You can leverage this mini-api in a number of ways:

  • you can paste these links into the Revizto Issue Tracker to allow you to jump between issues in Revizto
  • paste the links into Word or Excel or other emails as part of a larger report or conversation
  • inject these links into another BIM platform such as a Revit URL field, so that you can jump from a specific item in Revit to the related Revizto issue
  • use these special links in a project portal or project management system

This is just the beginning for a new era of connectedness between the Revizto Issue Tracker and other platforms… watch this space!

Revizto continues to improve its very powerful web Dashboard features. The web Dashboard gives a live view of issues for your team, and can be completely customised to give the most focused overview of your current project Status.

To create a web Dashboard and Group by Tag, just follow these easy steps:

      1. Open https://ws.revizto.com and access the Project you want to work on
      2. Click on Dashboard
      3. Click “Add New Dashboard”
      4. In the Dashboard view, click “Add New Chart”
      5. Customise the chart to include only certain tags, and enable the Grouping by Tags function. Below is an example:

In the above example, you can see how I included only the high level tags that are used (on this project) to keep track of the construction zone of specific issues. Then, the Grouping function slices those issues and gives us quick insight into the Zones requiring immediate action by the project management team.

I’m sure you can see how easy it is to setup powerful and focused dashboards to successfully manage your BIM and Construction team with these new web features in Revizto.

Here are the other currently supported Grouping categories in Revizto:

Models change rapidly at various stages of the project, and it can be useful to review model status between different revisions of the models.  What changed? Why?

There are a number of Model Compare tools out there, Navisworks has one built-in and there are addins for Revit. But what if you just want a quick visual check?

Here is one method using Revizto…

Using Two Instances of Revizto and the Issue Tracker to Compare Models

  1. Open two instances of Revizto and put them side by side on your screen (large monitor will help)
  2. On one of the instances, go to Project -> Revisions and open a previous version of your model

  3. You can now navigate between two different versions in these two instances
  4. The issue tracker data is always up to date, so you can use the Issue Tracker to co-locate yourself in each file and check the differences. Just click on the same issue in the Issue Tracker, and then click on 3D to visually compare the models. Obviously, you can also enter data and snapshots into the Issue Tracker as per usual, perhaps to comment on why a particular model changed between versions.

Another Idea…

Essentially, this idea was to launch two instances of Revizto and use the Camera Share tool to navigate the same model between them.  It was a bit more involved, and it requires you to have access to two different login accounts for Revizto, and two different login accounts for the current machine, and Revizto is installed ‘For Everybody’.

  1. Ensure you have psexec available
  2. Make a CMD with this text:
     psexec -u OtherWindowsUsername -p OtherWindowsUserPassword -d -i "C:\Program Files\Vizerra LLC\Revizto4\Viewer\Revizto.exe" /language ENU

    (needless to say that you should be careful to protect the password above)

  3. Open Revizto normally and login
  4. Run this CMD file, and in the new instance of Revizto you can login to a different Revizto account
  5. Open the same Revizto project in each
  6. You can now use the Camera Share tool to ‘drive’ both instances simultaneously. Pretty cool!
  7. In one of the instances, open a previous Revision of the model
  8. *This is where the idea fell down, as Camera Share no longer offered to share camera between two different versions of the model :)*  Evidently, it won’t let you navigate non-similar models at the same time.

I re-tooled the steps above from my previous post about logging into multiple Autodesk logins at the same time:

How to Workaround A360 SSO issues by Running another Instance of Revit in Same Windows Session as different User

Aerial imagery and 3D models are extremely powerful visual tools. Often, these are used primarily in early design and master planning. Some software tools connect directly to aerial imagery and 3D data providers. Unfortunately, Google has not really opened up the connection to their base 3D data. But we can capture imagery from it, and then rebuild in another photo-to-mesh tool, like Recap Photo. Keep in mind that you will be creating a 3D mesh, from an isometric 3D world view, which was created only from aerial images. Basically, your output will vary, and will probably not be high quality. But for the intended use in early design and master planning, the below workflow may be useful…

Note: Please investigate the license and copyright of this data for such use.

Here’s how:

  1. Open your desired 3D isometric aerial imagery in desired application (such as Google Earth, Google Maps or similar)

    *Note: User to be aware of relevant copyright restrictions
  2. Open ScreenToGif (downloads here). This is used to create snapshot images of the screen very quickly.
  3. Setup the scene, so that you have the ScreenToGif window appropriately overlaid onto your actual imagery
  4. Start recording, and slowly orbit at least 360 degrees as shown
    here
  5. In ScreenToGif, open the image folder
  6. Convert the images from PNG to JPG (I used Irfanview Batch Convert)
  7. Load into Recap Photo, make new Object project, spend 12 cloud credits and start the mesh creation
  8. After meshing, in Recap use the measurement scale tool to scale the model based on the distance between two known points

  9. Export the 3D Model from Recap. Various formats are available. In this case, I exported directly to FBX with Y-Up and imported straight to Revizto. You could also import FBX to AutoCAD and then to Revit, or you could bring it into Meshmixer first to delete some parts of the model via OBJ.

In Revizto, the direct FBX import looks like this:

Sheet overlay in Revizto. Simply with a PDF and some freely available aerial imagery, we now have a 3D collaboration workspace ready to go:

In the latest Revizto update (version 4.6.3, build 41736) you are able to change the UI scale in the General settings. This is very useful for 4K screen resolutions:

You can also set the Default Launch Screen as shown above.

The ability to update existing viewpoints is also present. You navigate to a Viewpoint, then as you move away from it a update icon will appear next to the viewpoint name. Just click that icon to update the Viewpoint. The video below shows this in action:
