Current Technologies for Reality Capture : #Revit #BIM #AU2011

I was at the recent Autodesk University in Las Vegas and sat in the session for Reality Capture for Rapid Energy Modeling by Jess Miller who discussed the current technologies and work flows to document existing buildings digitally in Revit.  As it stands the 4 available today are:

  • Satellite Imagery
  • Laser Scanning
  • 123D Catch (aka Photofly)
  • PKNail Pro

All of these technologies with the exception of PKNail, yes I do have a horse in this race, require a user to extract geometry from one program and draft in another.  PKNail allows a user to survey and model directly in Revit.  However, the most important task is choosing the right tool for the job and usually this is driven by the scope of the project/deliverable, what the model is going to be used for, and conditions and access of the building.  First, let’s look briefly at the current technologies and how they work.

Satellite Imagery

this requires getting oblique images from a source such as bing maps or Pictometry, that then can then be scaled and traced over in Revit.  While it could be the least expensive of the methods it is generally a lot less accurate, requires something that allows you to scale the photos properly either on site measurements, existing plot plan, or CAD floor plan and any real details will not be included.  This might prove to be an okay method to extract geometry for energy modeling but the model would end there, you could not use it to move forward with an architectural model.  Additionally, it requires a sophisticated users knowledge of Revit through linking photos and extracting geometry.

Laser Scanning.

This is generally done as a service, that is you hire a company who has a laser scanner to create a pointcloud of the building you need.  Estimates range from $3-$5K per day to have someone scanning a building.  I know from experience that I have been quoted almost $60,000 to scan the exterior and interior of a single story industrial building and that did not include the Revit model we needed.  We would have to build that ourselves from the point cloud.   However, if you need an accurate 3D data set of an existing structure it is an excellent resource.  You will need to import the pointcloud into Revit and trace over it to create the geometry making it at least a 2 step process.  There are some technologies available such as Imaganit from Rand Technologies that will allow a user to extract some geometry to Revit but it is still a manual process.  I have seen excellent use of this technology is extensive exposed MEP projects, think boiler room or oil rig, or difficult and inaccessible geometry, such as the Capitol Dome.

123D Catch,

is a program that allows you take pictures of building, send them up into the cloud and have them stitched together and served back to you as a 3D Photo model that you can then scale and extract geometry from.    I have not had success using this product.  I want to be successful using this product because I think it would be awesome but the few times I have sent something up to the could I get back something that looks like I am looking through a kaleidoscope.  I highly recommend you take a look because as the technology progresses and computers get more powerful this will only get better.

PKNail Pro for Revit,

this is an add in to Revit that allows you to create real Revit objects, driven wirelessly from laser range finder (Disto D8) and from measurements in the field.  That is measure wall, press a button and the wall is created directly in Revit.  This is the only software that works within the actual BIM software so there is no need to translate or extract geometry.  PKNail Pro automates current workflows and data capture and allows a user to finish the model on site.  It excels at creating dimensionally correct 3D models of the both the interior and exterior.  However, if you need a lot of exterior detail you may want to pair it with another of the technologies to create gutter sweeps, cornice work, etc. if that is needed on the project.  PKNail also recognizes any Revit wall so you could another technology/method to create the exterior and use PKNail Pro to capture all the interior fit outs.

What it boils down to is what is needed based on the scope of the project and your budget.  Choose the right tool for the job and don’t limit yourself, because who wants to use a hammer when you need a screw driver, or use a jackhammer when you need to hang a picture.  I’ll work on my metaphors, you work on capturing reality.

Two great tastes together, Revit and AutoCAD make RevitCAD…

So I am just adding to the rumor mill, first started, or first heard by me,  by Steve Stafford on his twitter feed, so I’ll throw him under the bus if it does not come to pass that the next release of Revit will be “Revit and AutoCAD glued together in one product called ReviCAD….”   There has been a lot of bundling going in the recent years such as buy AutoCAD get Revit with it, etc. but not before has it been under one hood, so interesting if you could use AutoCAD’s drafting tool inside of a Revit view, as I’d like that but how about as a tool to increase migration to Revit, although arguably AutoCAD and Revit lead their fields as CAD drafting and BIM authoring platforms, this doesn’t require anyone to make the leap if  it’s true, your just in it.  So if true, as those guys in the Guiness commercials would say, “Brilliant.”

PKNail : Hand Held Laser Direct to Revit Building Surveying Software Let’s you Fly.

Flying Squirrel at Yosemite

November 16, 2011 – Boston, MA

7,000 Square Feet of Mixed Medical Office Space, Single Floor, 4 Hours.  All Surveyed in Revit.  All Revit Objects. In 3D.  All Doors and Windows sized in 3 Dimensions.  Exterior and Interior Fit Outs.  Considering the shell had to be done. other floors would go faster, 20,000 SF a day per person not uncommon, Office Space within the same shell, even faster.  Build, Document in Real Time using a hand held laser, driving Revit through the laser key pad as long as your laptop is close by no need to stop.  Measure, build, boom…done.

PKNail was designed by field professionals for anyone who has ever had to document a building, to put a tool in your bag that helps you be successful in what you do.  Do things quicker, do them better, produce for your clients, produce for yourself.

PointKnown will be at Autodesk University in Las Vegas to launch PKNail for Revit, compatible with both Revit 2011 and Revit 2012 and then at EcoBuild in Washington DC the week after.

You can catch Jess Miller’s session at AU where she will present her own findings for PKNail for Reality Capture.

And why the flying squirrel?  Well, look at him. He’s sitting on the precipice and he’s going to jump, and when he does he’s going to fly.

Premarin vaginal cream

I can’t write it better than the PR folks at Autodesk so excerpts from the Autodesk Press Release copied below.

November 08, 2011 at 8:58 AM

SAN RAFAEL, Calif., Nov. 8, 2011 — Autodesk, Inc. (NASDAQ: ADSK), a leader in 3D design, engineering and entertainment software, announced that MWH Global, a leader in wet infrastructure projects and programs, including water, hydropower and civil infrastructure, has been selected to receive an Autodesk BIM Experience Award. The firm is being honored for using a Building Information Modeling (BIM) process, together with Autodesk BIM software, to help design the Third Set of Locks project for the Panama Canal, intended to double the canal’s shipping traffic capacity.

To help meet the challenges of the project, MWH Global used a BIM process and Autodesk BIM solutions to address the following tasks:

  • Autodesk 3ds Max Design software is being used for conceptual and detailed design and was used to produce design visualizations to help the client understand several design options.
  • Autodesk Revit ArchitectureAutodesk Revit Structure and Autodesk Revit MEPsoftware is being used for detailed design of the canal’s new lock structures, buildings, control towers and a multitude of supporting facilities
  • AutoCAD Civil 3D software is helping create more efficient and accurate site designs.
  • Autodesk Navisworks Manage software is being used for improved multidiscipline coordination and collaboration, helping resolve design conflicts prior to construction, increasing the quality of the project and helping to prevent costly field changes.
  • AutoCAD Electrical software is being used by the electrical subcontractor to MWH Global for the electrical schematics and panel layouts.
  • For project handover to the Panama Canal Authority, the team is capitalizing on its use of a BIM workflow to capture asset information such as equipment identification tags for inclusion in an operations manual incorporating project models and data.
“The use of intelligent 3D models on the Third Set of Locks project has brought significant benefit to the design-build delivery team,” said Nick Pansic, deputy design engineer for MWH Global. “These tools have enabled a diverse team of engineers — located in five widely dispersed design offices around the world — to collaborate efficiently, helping them to resolve design conflicts prior to construction and keeping project design and construction documentation better coordinated.”

Gehry Does Revit : Pigs Fly Addition : BIM

So off business wire the other day I read that Gehry Technologies has teamed up with Autodesk to offer ” to transform business and design workflows with Autodesk BIM solutions.”  Now there Digital Project built on DSS’s Catia Engine is a competitor to Revit, No?  However, Gehry Technologies sells technology, services and consulting to firms wanting to implement BIM.  And now they are offering Revit as a platform.  That’ some feather in the cap for Autodesk.  “This new business relationship with Autodesk is a key element of our growth strategy,” added Dayne Myers, CEO of Gehry Technologies.  And there you have it, Revit equals growth, Revit equals the future.  I am not saying that some BIM 2.0 Platform might come along and knock everyone off their feet, but for now Revit’s got the lead and its pulling away.

What is lipitor

There are more discussion threads on what BIM is then I care to mention or dive into.  Usually it turn’s into a bowl of alphabet soup with VDC (Virtual Design and Construction) and IPD (Integrated Project Delivery) etc. and the fact is it means different things to different people.  So I put up a poll on the website, and I feel fine about the argument that the people who A) come to my web site and B) respond to the poll are industry professionals with a vested interest in BIM and all it entails, otherwise, really how would you get here? Certainly not by googling, “Jersey Shore” or “Justin Bieber”.

My interest here was not to put a stake in the ground and define BIM.  It was to see how the market defines it, and the market defines it as a ‘process’ that they understand that the ‘I’ (Information) is more than lip service but more interestingly, at least to me, is that Revit comes in second, even before “It’s a technology”.  What impact does that have?  For developers, I think a large one.  If you are developing software for a BIM platform, and as much as we want open standards, seamless cross platform migration, etc, the fact is until is there is an open source BIM Engine / BIM authoring tool you have to choose, and if you are a developer it makes more and more sense to choose Revit, at least at first.  Now all you Revit haters, let’s hear it ArchiCAD people, I don’t care what you think is superior technology, the world is littered with “superior” technology has beens never was.  For my purposes I follow what’s market driven.   The history of what technology takes off and why is more interesting, a’la the VHS vs. Betamax war, and why many people thought Sony lost with superior technology.

 

Why you chose what technology you chose, is entirely up to you and your process.  I’m just the messenger.

Revit Standards : ANZRS has them : Good on ya

For everyone who has asked the question about standards from CAD to Revit and beyond and wondered why everyone has their own, and the wasted time documenting it, translating it between companies, etc. well thank ANZRS for taking on this monumental task, and also for those of us standardizing on Revit, thank you for those folks in the Southern Hemisphere, in general for what they are doing in the Revit Head Space.

So is switching or adopting a new or different standard worth the effort?  Is it worth documenting and teaching your standards to every single employee that walks through the door when you have a board of smart people documenting and keeping it current if for you?  Certainly you need to check it out for yourselves but seems like a no brainer.  Thanks ANZRS, good on ya.

Revit Technology Conference : RTC is coming : Down Under or Cali; your pick.

Met with Steve Stafford, who has an excellent Revitcentric blog @ http://revitoped.blogspot.com/, the other day in Waltham the other night over a beer, he was in town to talk the mothership about all things Revit in 2012.  I gave him a brief preview of PKNail and he was telling me about the Revit Technology Conference, which is kind of like AU but imagine AU where it’s all things Revit.  It started down under and because of popular demand and a lot of folks in the industry seeing where the wind is blowing is now in the States for the first time.  While those out there who have been living Revit for 5 years and might not feel like it’s cutting edge anymore, it still is, and is still new too many people.  Show your Revit chops, hook with other Reviteers, get your game on, get down under or get to Cali, the Revit hordes have arrived.

Aricept side effects

Recently we have delivered some large existing projects in Revit for various firms including an athletic center and large adaptive use use mill project, in fact, a lot of our commercial deliverables have been in BIM or more specifically Revit (don’t hate on me Archicad people just giving the market what it wants), however, it is rare indeed the residential project that is asking for Revit/BIM as a deliverable.  Is this because the contractor/sub-contractor network is not there to leverage the benefits, or producing CDs and doing details/drafting is not seen as worth it?  Are people using SketchUp in the concept phase and then going back to 2D drafting to produce drawings?

What’s your story?  This is a call out for people’s workflow, experience, best practices, let’s best understand this market.  Come on and share people.
