BIM Collaboration

28 Apr

Coordination guidelines

This content is published to provide advance information to parties collaborating with TKA

This approach considers the modeled information to be the primary source of truth; therefore, it is expected that content contributed by consultants follow this same logic:

 

Two-dimensional documentation is to be extracted from the 3D model – the 3D model is NOT to be generated as a parallel effort to 2D drawings.

 

In general, all content that is depicted on document deliverables according to the acceptable standard of care is to be modeled in an agreed BIM platforms documented in a Project Execution Plan or BxP. For design development and construction documents, modeled elements are to be created to a design level of detail – either generic [LOD200] or specific [LOD300], depending on the requirements of the project.

 

Collaboration

Consultants are expected to share BIM data with TKA and other members of the design team. Models must be uploaded to a project collaboration system on an agreed schedule, set forth in the BxP.

Naming of models will not change during the project lifecyle. (Versions will update through the transferring system)

 

Model Element Authoring Table

The Model Element Authoring Table (MEA) is a more detailed specification of the modeling responsibilities throughout a project team. In other words, who will model what, and when. This will become a critical roadmap by which to measure each team member’s compliance with the modeling plan.

LOD’s

More information about level of development can be found in the LOD Specification BIMForum 2013

 

LOD100 “Estimate it.”

LOD200 “Specify it.”

LOD300 “Bid it.”

LOD350 “Buy it.”

LOD400 “Build it.”

LOD500 “Operate/maintain it.”

Model-Based (3D) Coordination

At specific project stages (depending on the details of the BxP), it will be the responsibility of a multi-discipline firm to be self-coordinated BEFORE transmitting the models to the team. For example, mechanical, electrical and plumbing models being prepared by one engineering firm must be coordinated with each other before integration with the architecture and structure models.

Sub consultants using Revit will be responsible for creating a Navisworks export, to be delivered with the original Revit files, according to the collaboration schedule set forth in the BxP. This requirement ensures that the Sub consultant retains responsibility for the model content exchanged from one platform to another.

Template clash tests

 

TKA team has developed a series of template interference tests in Navisworks to facilitate 3D Coordination during design phases. 

Within the BxP template, the design team will agree to the clash tests to be conducted during the design phases. This will set the expectations for any other recipient of the design models, such as the builder or client.

Clash Resolution

It is the responsibility of the Architect to supervise the 3D Coordination process; however, each Sub consultant must participate in the resolution of clashes in order to achieve the stated quality control goals of the project.

In addition to participation in inter-disciplinary clash resolution, Subconsultants are responsible for performing self-checks (intra-discipline) on model content BEFORE the models are distributed to the team. This means that there should be no interference clashes in testing structure versus structure; and HVAC versus HVAC; and so on.

 

 

Collaboration Technology

TKA employs several technologies to support an advanced level of collaboration with our extended design teams as well the owners and builders to whom we provide services.


WebEx

TKA’s enterprise solution for web-based conferencing is WebEx by Cisco. Project meetings can be conducted with many constituents with the options to use toll free phone access or the microphone and headset connected to the computer. Meetings can be recorded for future reference and played back with a free player available from the WebEx website.

 

Newforma Project Center

TKA utilizes Newforma Project Center and InfoExchange for all project management and collaboration. All design data artifacts are transmitted via the TKA InfoExchange site. 
If your firm also utilizes Newforma Project Center, there may be opportunities to streamline the connection with an TKA project team via automatically synchronized project folders. Please contact the TKA IT Department  for more information.

Citrix XenApp

 

TKA’s major projects maintain hardware that supports Citrix XenApp – a system that offers extended design team members on-demand secure access to enterprise applications. This tool eliminates the need to send large design files over the Internet. Instead, remote users can run software such as Revit via a web-browser without ever moving a file off the project server.

While this platform is not used on every project, it has proven to be extremely effective on large projects with design team members in various remote locations.

Recording a Scene Animation to convert to a Viewpoint Animation in Navisworks

7 Apr

What Revit Wants: Recording a Scene Animation to convert to a Viewpoint Animation in Navisworks.

You probably know that you can import a Viewpoint animation into a Scene animation in Navisworks, like this:

Animation Ribbon – Animator

Add Scene

Right click on the Scene, Add Camera, From Current Viewpoint Animation

 

 

Ok, that’s fine. But what if you do some work on the Scene Animation, add keyframes, adjust pacing, and then you want to convert it back into a Viewpoint Animation? Here’s how you do it:

Open Animator and get a Scene animation ready to press “Play”

Animation Ribbon – Click the Record button

Click the Scene name, and the Play button will activate in Animator

Press Play in Animator, and wait for your animation to complete

Press Stop in the Ribbon

 

Press the Record button again to toggle it “off”. Navisworks will now save the Animation into your Saved Viewpoints

Delete any unnecessary Cuts etc

 

 

With this tip, you can now convert to and from a Scene and Viewpoint animations as needed. Viewpoint animations are a bit easier to put together, but it might be easier to adjust the pacing in the Animator. Obviously, the Animator has more power and control if you intend to actually animate objects in your scene.

 

On a related note…

I’ve come across a bit of a bug in Navisworks 2015 with Viewpoint animations and huge models (like 2gb huge). If you have a Home view with Hide/Required and Materials set, and all your Animation views have those options unticked, then you should be able to flick to your animation without losing your colours, right? Well, in some cases it seems to work, but in others it seems to reset the appearance whenever I switch to the animation, meaning I lose colour overrides.

 

I tried working around the color issue like this:

Open project

Make a new folder

In the folder make a new animation

Drag all of the views from previous animation to the new one

Collapse the Animation

Switch to a view with Hide/Required and Color applied (ie. Home view)

Click on the new animation name (OK, doesn’t seem to reset colours)

Expand and click a view (sometimes works, maybe, but can also fail)

Another workaround is to switch to your coloured Home view, save a 2013 version NWD and work in Navisworks 2013. Sometimes the downgrade bakes the colours into the elements, meaning you don’t lose them when you switch to and from the Viewpoint Animation.

To Compare Two Versions of the Model

24 Dec

In-Product View

To compare two versions of the model

  1. Open the first file that you want to compare in Autodesk Navisworks.
  2. Click Home tab >Project panel >Append drop-down >Append , locate the second file, and click Open.
  3. Hold down CTRL key, and select both files in the Selection tree .
  4. Click Home tab >Tools panel >Compare .
  5. In the Compare dialog box, the Find Differences In area, select the check boxes for all required options.
    Note: The Overridden Material and Overridden Transform check boxes relate to changing the color and transparency in Autodesk Navisworks, and changing a file’s origin, scale or rotation since loading into Autodesk Navisworks, respectively. These check boxes are clear by default. All the other criteria relate to properties of items from the original CAD model.
  6. In the Results area, select the check boxes to control how the comparison results are displayed:
    • Save as Selection Sets. Saves the items that you are comparing as a selection set. You can then use this set for later comparisons between the same items.
    • Save Each Difference As Set. Saves the resulting differences found in the comparison between the two items as a selection set for later analysis. The selection set will also have a comment attached detailing the differences in more depth.
    • Remove Old Results.Removes any selection sets resulting from a previous comparison, in order to reduce confusion when looking at the results.
    • Hide Matches. Hides all items that turn out to be the same in the comparison, when the comparison finishes.
    • Highlight Results. Highlights each resulting difference with a color override, when the comparison finishes. You can reset the colors back by clicking Home tab Project panel Reset All drop-down Appearances .

Navisworks Keyboard Shortcuts for blazing fast clash reviews using Autohotkey. Note that the Num Lock must be turned off for this to work!

Navisworks Keyboard Shortcuts Included in the zip file is the executable, the autohotkey source code if you want to customize this to your liking and a pdf that shows what the shortcuts are.

Most of the shortcuts are self explanatory but they do some very handy things.

0 – sets the clash to Reviewed and brings up the assign to dialog assign is a great tool to organize your clash reports and add comments for sending out to subs

1 – sets the clash to Reviewed and then automatically moves on to the next clash my clash reports only contain clashes set to Reviewed, in my world Active means it still needs to be reviewed

2 – moves to the next clash in the list without changing the status

3 – set the clash to Approved and moves to the next clash

4 – selects the clashing object in the left side of clash detective and zooms to that object

5 – full screen if you have 2 monitors I recommend putting Navisworks on the second monitor, this way when you use full screen it puts the full screen view on the left monitor and leaves all you tool palletes open on the right monitor

6 – selects the clashing object in the right side of clash detective and zooms to that object

7 – selects the clashing object in the left side of clash detective and turns on the select filter the select filter is a great way to quickly slim down the number of clashes, if you dont use it then go learn it now!

8 – moves to the previous clash without changing the status

9 – selects the clashing object in the right side of clash detective and turns on the select filter.

. – focus on the overall clash this is great if you get lost in your model

/ – Sets navigation to classic walk mode – sets navigation to classic orbit

– – sets the clash view to Dim other

+ – sets the clash view to Hide Other

If you use other programs while using Navisworks you can simply turn Num Lock back on and this shouldnt affect any other programs.I hope this proves to be useful for everyone and I hope it inspires others to share the tools they have developed. I believe sharing is important to move us all forward as a group. Please provide feedback and any other ideas you may have to improve the
