”Jim your a go….” 2:40 PM, New Years Eve 2012. Text from our client; Mark at Looney & Associates
Our work window was January 3rd through January 9 2013. Travel arrangements and team needed to be assembled for flights in two days. The only thread holding this together was PKNail Pro.
Team members included individuals from Langan Engineering, Turis, TrueScan3d, LandAir Surveying and my company Interioreview. The Job: Survey and Document Floors 2-7 of the Royal Sonesta Hotel, 300 Bourbon Street. Include structure, electrical objects (Duplex, Com Ports, Thermostats, Wall Lights, etc) and Fire Protection. 450+ Rooms, Common Spaces, Administrative Spaces, +200,000 SF. 1 Week. From Blank Screen to Floorplans and RCP.
“This is innovative stuff…”, Greg Jensen, Langan Engineering
“…Boom, your done.” Brady O’Brien, Turis Systems
“This certainly opens the door for future teaming efforts, and we’ve already begun to push PK Nail on some of our interior projects – integrating it with scanning and traditional survey.” – Paul Fisher, VP Langan Engineering.
This project could not have happened without the participating firms willingness to deal with such a tight deployment deadline and with the excellent individuals that arrived in New Orleans. It also could not have happened, and I do have a horse in this race, without PKNail Pro and Revit. There was simply no other way to coordinate multiple personnel field surveying without both. We were able to deploy resources as needed since everything was being surveyed and modeled in real time. 4th Floor, South Wing, Greg get on it. Brian, 2nd Floor with Nico etc. This also allowed us to create a punch list in real time. Reflected Ceiling on 3rd Floor, etc. as all the files were compiled daily, if not more often into a central file. Although the deliverable will eventually be in 2D Autocad, all the initial documentation will be in Revit, so even though it was not part of the scope, we will be able to deliver a typical section through the building with only a small post processing effort.
Lastly, thank you to the good folks at The Royal Sonesta, New Orleans for treating us so well. They understand hospitality and have a great team.
More and more firms are relying on PKNail Pro for documenting buildings whether they need the final deliverable in Revit or 2D Autocad. PKNail Pro can deliver.
Autodesk announced the release of 123D Catch for the iPad. I have not yet tried the iPad version, but assume it’s mostly the same since before you chose the photographs to be sent to the cloud, and now it is sending photos you are taking from the iPad. One of the criticisms I had with it before is that you had to follow a very particular way of taking photos, which apparently I was not very good at because all my results came back looking like a kaleidoscope. However, everybody is looking for an iPad app/strategy these days and this helps. And if you get good at framing the pictures, using this on site to get basic 3D geometry, most likely for massing purposes or some initial energy analysis, well that’s very cool.
Autodesk digging into the Built Environment : Augments ‘Reality Capture’ Stable by acquiring Alice Labs
80/20, the amount of construction projects that happen in the built environment vs. new construction, at least here in Boston and this is usually the case across the globe, maybe not 80/20 but having the majority of construction happening in the built environment. So if you’re Autodesk and you have all this great software, you can no longer presuppose the data, you are going to have to capture it somehow.
Autodesk put another arrow in their ‘built environment’, ‘as built’ or soon to be trademarked “reality capture’ quiver by acquiring Alice Labs. As reported in Graphic Speak, Autodesk Scoops up 3D point cloud innovator Alice Labs. And if you go to the Alice Labs website, all you get is a splash page saying they have been acquired by Autodesk, and no press releases from Autodesk either. Why not? Autodesk is like the borg, well I can’t comment on the assimilation part, but as far as sucking up cultures within their universe, no problem. So why not let people know.
The small team, closely related to ongoing research at technical universities in Delft, Netherlands and Ghent, Belgium, has previously released Studio Clouds, an innovative 3D laser point cloud editing technology that offers plug-ins for Autodesk’s 3ds Max and Maya modelers, and uses a proprietary game engine for fast manipulation of point cloud data…Behind the application is the Mirage Nova Engine (MNE), said to be capable of handling billions of points with ray-trace visualization quality. NME also offers a photogrammetric tool, offering an affordable way to generating high fidelity point cloud models from photographs. MNE is designed for 64-bit multi-core architectures and can take advantage of graphic card acceleration for maximum speed. -Randall – Graphic Speak
Either way, Autodesk is interested in getting you working in their software whether it’s for new construction or the the built environment, designing retrofits or modeling New York for gameplay. If it’s a 3D environment they want to put you in it, and Autodesk wants to be the transporter…Kirk Out <end cheesy Star Trek word play>
Autodesk has been concentrating on incorporating their energy modeling tools into their workflow, so much so, they are now calling it Rapid Energy Modeling and have outlined a variety of ways to capture a building’s geometry digitally so you can run it through their energy modeling engines. They outlined the following techniques/methods as the most cost effective for capturing exisitng conditions. Full paper available here: rem_white_paper_2011
These are photographs of your building taken specifically for rapid energy modeling.
You can download oblique aerial images from Internet sites such as Google Earth or Microsoft®Bing™ mapping services. Alternatively, you can use images from commercial providers of geo-referenced aerial and oblique image libraries such as Pictometry.
Like aerial images, you can download orthogonal images of your building from sites such as Google Earth. RAPID ENERGY MODELING FOR EXISTING BUILDINGS
Laser distance meters
These low-cost laser meters are common surveying tools, and you can also use them onsite to capture key measurements of your building.
PointKnown was cited as the software to use when utilzing laser range finders and capturing a building in revit.
If you plan to capture existing conditions using a laser distance meter, you can use PKNail software from PointKnown (www.pointknown.com) to process those measurements and create a Revit model of your building. By inputting a few simple field measurements PKNail will build a Revit model of the existing structure, in the field, in real time.
This approach involves trained survey personnel that walk around the perimeter of a building and measure key points on the building. The PKNail software utilizes Bluetooth®-enabled laser distance meters to capture dimensional data in the field and send it directly to a laptop loaded with the Revit Architecture or Revit MEP. By capturing data in a specific sequence, the PKNail software creates a Revit model representing the skin of your building as it is being measured.
While we wait for the ‘magic wand’ that digitizes existing buildings while you walk through it, and when I mean digitize, I mean scaled, architectural objects that can be scheduled, processed, etc. more and more technologies are being developed to speed the ‘realty capture’ of buildings. The argument for using PKNail is that the exterior model you build is natively in Revit Architecture and if you want to move inside for interior wall partitioning, etc. for adaptive reuse, etc. you can do that all by utilizing the key pad interface and the laser meter.
Not changing the world just making your day to day a little easier, increase productivity, get more accurate, teeing it up so you can knock it out of the park.
I cannot pronounce much more than it exists as I have not had my hands on one, and the video included below seems to use it mostly for layouts, not for data capture. NAFTA Leica_3D_Disto_Word-Flyer1.0 . However, when Pointclouds seem excessive from a data and price perspective, and one needs to determine points on inaccessible or complex geometry, this could be the aspirin (does anyone take aspirin anymore) to that headache, or for that matter doing complex ceiling systems or even reflected ceiling.
So what’s on board besides the laser? Camera with 8x Zoom so you can see far off points and DXF input and output and while there is some more stuff that seems to be the most important and data transfer to anything else is via USB stick. Why not include bluetooth as almost every laptop, netbook and the new iPad comes with it and seems a glaring omission. How about if it came with an ‘app’ for iPad and Android instead that could drive instead of its own proprietary piece of hardware.
I wonder if you can move it around in the same room because most rooms I know of are not completely open with shots available to every point you needs, and how you would coordinate points for integrated output? There is some software available called ‘Room Scan’ but have not seen enough of it to know.
MSRP is set at $7995 so up to surveyors, etc to think if it is worth the price tag.
Thanks for Bruce Lang for bringing this to my attention. Browser Plug In to Navigate the Earth, many cities are in 3D, I quickly browsed the East Coast and both Boston and New York look pretty sweet. Utilizing technology from C3 and from their blog:
C3 uses modern camera equipment to capture as many as one image per second of the same object from up to 100 different angles. The images are then used to automatically reproduce the shape of the objects with very high accuracy. After that, an image processing software automatically drapes each shape with the texture chosen from the pictures of each object. The same process is being applied for all objects – buildings, houses, trees, and hills – the result is a seamless canvas of 3D-data where the resolution (8 to 12 centimeters per pixel) and quality is consistent over the entire model. This is the secret to C3 maps’ realistic look compared to competitors’ hand-made and cartoonish appearance.
You can get the plug in here. Understand that the photo is screen shot from the product, you can spin it around change perspective, go around the building to the other side, sweet.
However, Why? Think of it this way, how many times do you use google maps, or live maps, in a week, in a day, to navigate, to check something out and then think of all the ways I can sell you stuff if you are using/looking at my map? So if I have better eye candy to get you in my store, so be it. Not like Nokia is a small company but certainly like to see people swinging at the hegemony. And did you notice the comment ‘competitors handmade cartoonish appearance.’ Who you talkin about Nokia.
Interestingly enough, while at Autodesk University, Pointools announced their plug in available for SketchUp. Make the jump to read all about it, but I guess with this announcement maybe the next thing we’ll see is the Google car with a scanner on top instead of just a camera. Google and Autodesk are now squarely in the same ring.
As reported by Matt Ball, Brian Mathews, the Autodesk VP in charge of Autodesk Labs, gave a media briefing updating ‘his Seven Technology Trends lecture with example projects.’ Reality capture or as otherwise stated, turning analog into digital, being #2 on the hit list. So capturing the Built Environment is starting to get serious traction, and while I hesitate to use the word traction, well, that’s what its getting.
Previously in the conversation people would talk about all the wonderful things software can do for buildings, then you realize the majority of construction is in the built environment and it becomes, well just give me the building, or at lest the digital equivalent of the building and look at the wonderful things software can do, however, most presupposed the digital equivalent of the building. Not anymore, more and more companies are releasing software and tools to capture the built environment, or call it reality capture if you like, but soon there are going to be a lot more tools on your shelf.
Autodesk has released, Project Photofly . and will soon release Project Galileo which according to its splash page, “is an easy-to-use planning tool for creating 3D city models from civil, geospatial and building data, and 3D models.” Plus Autodesk has release shape extraction tools from PointClouds directly inside of AutoCAD. Rand Technology/Avatech/Imaginit hybrid has released PointCloud manipulation tools inside of Revit and we are in the final beta of PKNail, a PPLT (Point to Point Laser Technology) system that allows a user to drive Revit commands and enter dimensional data directly from a range finder allowing a user to build a Revit model in the field. Plus we recently saw the beautiful kinect hack allowing a user to capture and even measure 3D video. I can’t say which technology or mixture of technologies will work best for you, but your job is going to get easier.
Is it fair to continually compare Revit and SketchUp as essentially they were doing two different things, Conceptual Modeling as compared to Building Modeling, not anymore with the release of Project Vasari, alive and available for download. It is available as a preview and free until May 15, 2011. I will be downloading it shortly, and from the looks of it and as posted by other bloggers, like the Revit Kid and David Light here are some of the features:
- Stripped Down Revit User Interface
- Built in Energy Modeling
- Produce conceptual models using both geometric and parametric modeling functionality
- Cross Compatibility between Revit 2011 and Vasari files.
In fact, I even suggest to jump over to David’s post to get a more in depth look at Vasari and its features. However, what has been apparent to me and others was for Autodesk to round out their line up with a conceptual modeling tool, and with something that had the ease of SketchUp. Why? Because I would speak to architects who had never even fired up any CAD package who said they are now using SketchUp, plus with idea of a Revit Light you can create an easy entry point for users rather than be bamboozled by full Revit UI/Ribbon/Feature smorgasbord. In addition to the easy entry point models created in Vasari can be opened in Revit 2011 and visa-versa so going from concept to modeling in Revit Architecture should be easier, conceivably, although I have not seen that work flow.
I imagine pricing, when the free release ends, has to be somewhere within the SketchPro version which is at $495. But not sure how that would work through the VAR channel, maybe it’ll be free as an entry point or lead generation tool. SketchUp also allows you to trace photos to try and recreate real world elements, plus validation and analysis. There’s a battle going on for building design and life cycle management; makes you wonder what Google produces or buys next – a BIM authoring tool, or possibly model integration a’la Horizontal Glue. The global AEC industry is $4.6 Trillion, and if you think of buildings as customers, energy customers, retail customers, services customers, why wouldn’t you want to be a part of that. Score one for Autodesk.
