- Enable planners, engineers, and designers to model existing infrastructure and import detailed models in order to create realistic 3D models of the environment;
- Sketch early-stage designs directly into 3D models;
- Create and manage multiple alternatives;
- Communicate visually rich infrastructure proposals; and generate preliminary design models which can be used to create submittal documentation in civil engineering software, such as AutoCAD Civil 3D.
In the following post we’ll describe how to use existing information to create compelling 3D design visualizations with MAP-21 (Moving Ahead for Progress in the 21st Century Act) requirements in mind.
If you are installing Autodesk Infrastructure Modeler for the first time, review the hardware requirements to ensure your hardware will run the software efficiently. (For more advice on the best hardware configuration for Autodesk software, review our series on AutoCAD 2013. Much of the same advice applies to other Autodesk products.)
Once installed, to create a realistic 3D model using Autodesk Infrastructure Modeler:
- Start Autodesk Infrastructure Modeler and click new from the start page.
- Choose a directory and name for your project. If you know the extents of your project you can also enter them in here.
- With the project started, data is imported and used as the basis for your 3D model. Autodesk Infrastructure Modeler allows you to combine 3D and 2D data in order to create a full 3D scene. For this post, we will use a terrain model (DEM) as our base 3D layer, and all of the other contextual data, like imagery, roads, and buildings come in 2D formats. Click on ‘Data Sources’ from the ribbon; on the ‘add file data sources’ dropdown, select ‘Raster’. After import this data source shows up in the ‘Data Sources’ panel. Double-clicking the data source allows you to modify the viewing properties of this data source. Click the ‘Close & Refresh’ button at the bottom of the configuration window to generate a 3D visualization in Autodesk Infrastructure Modeler.
- Add imagery using the same procedure.
- Use the same process to add roads, but use SHP as the Source Type. In this example, roads are stored in a 2D Shapefile. After import, double-click on the newly imported data source to configure it. Select ‘Roads’ as the ‘Type’ in the dropdown list. With ‘Roads’ selected you can now configure the roads style and other properties based on the metadata that comes with the Shapefile. For instance, you can choose a style rule to match the 3D road style (striping, sidewalks, median, number of lanes, etc.) based on existing metadata. Click the ‘Close & Refresh’ button on again to generate the 3D visualization.
- Lastly, we’ll add buildings to our scenes using the same procedure outlined in step 5. Select ‘Buildings’ as the ‘Type’ in the dropdown list. Since the buildings in this case are 2D footprints, we’ll select an attribute with a Z-value (elevation or height) from the ‘roof height’ dropdown. Once again click the ‘Close & Refresh’ button.
Voila! You have just created a 3D model using Autodesk Infrastructure Modeler. You can use this model to sketch preliminary designs of new infrastructure which includes roads, railways, city furniture, water areas, and even buildings. You can also exchange information with Civil 3D – using the IMX file type – to maintain consistent data and context as the project is further developed. This 3D model-based approach enables you to deliver on MAP-21 requirements for 3D modeling and visualization, on infrastructure projects of varying scales.

In Part 3 of this series, I showed you some of the collaboration functionality of Autodesk 360. We are now going to look at how we can synchronize our documents and drawings using Autodesk 360, using a fixed location (PC on a network) and a mobile location (iPad on a remote site with Wi-Fi), like in Part 3.
Your Documents Are Ready To Go, What Happens Now?
In Part 3 of this series, I mentioned that your documents were already synced. The synchronization tools you get with Autodesk 360, either in your fixed location or your mobile location, give you great flexibility. Especially if you are mobile on a tablet such as an iPad. Any changes you make using AutoCAD WS (for example) can be synced up to Autodesk 360. Be aware, though, that you can store ANY kind of document on Autodesk 360. We are talking MS Word or Excel docs, not just drawings and models.
So like in Part 3, you’re logged in with your Autodesk ID and you have synced your existing documents from your fixed location (PC on the network) to the cloud (Autodesk 360).
Making And Syncing Changes In A Fixed Location
I have selected one of the Word docs I have uploaded, which are the three previous parts of this series. The selected document is “Intro to Autodesk 360.” You will notice I have control over comments (right-hand side) and I have commented “This document needs to be archived.” Currently, this document is NOT set to be shared. Public sharing is switched OFF (bottom). If sharing was on, the comments function is a great way to add “unofficial” comments on any document, drawing or otherwise, almost like you would talk to each other on social media, a bit like Windows Live Messenger, for example. It is a superb way of working in a fixed location and letting the staff on a site know what needs to be done, aiding productivity. There is also the facility to download the document, which I will discuss in a moment.
So, if I clicked on DOWNLOAD now, Internet Explorer (IE9 in this case) prompts me to Open or Save the document.
I am going to OPEN the document and as I have MS Office on my laptop at my fixed location, Windows will open the file for me and I can then get on working, regardless of where that document came from, which could have been a remote site on the other side of the world, again aiding productivity.
If I go back to my overall list of Autodesk 360 documents (just click on Documents at the top of the Autodesk 360 screen), and I hover over the document, you will see small icons highlighting that I have made a comment on the document.
When I click on the Actions icon (arrowed) and click on Versions on the sub-menu, Autodesk 360 give me a chronological order of the versions of the same document, allowing tracking of the document and its various versions.
The versions of the document are displayed on the browser screen as shown below:
I can upload a new version of the document, or if I click on the small clock icon, I can revert to a PREVIOUS version if required. Autodesk 360 prompts you about this if you decide to do it.
Making And Syncing Changes In A Mobile Location
So let’s look now at our mobile location. I am running Autodesk 360 and AutoCAD WS on my iPad, and I am going to change a drawing using AutoCAD WS.
Upon logging in to Autodesk 360 on my iPad, I see the recent history of the MS Word document. So, my changes have already been synced live in the cloud in Autodesk 360. This speeds up collaboration time, especially when working together as a team on project drawings where the masters are stored on Autodesk 360.
Using the same process as above to find a drawing this time, but using the iPad remotely on a Wi-Fi connection, I have downloaded the drawing A3 Training.dwg in to AutoCAD WS for the iPad.
If some changes are made to the drawing on AutoCAD WS REMOTELY, these changes will be synced to Autodesk 360 immediately when the drawing is saved. I have added two red circles to the drawing, as shown below.
After selecting Done in AutoCAD WS, the drawing is saved. I then need to select Sync in the drawing list and the new revisions to the drawing (the red circles) are then saved to that version of the drawing in Autodesk 360 as well.
Once the remote sync is complete (on AutoCAD WS), the fixed location can then check the changes on their Autodesk 360 back at the office.
By clicking on the Actions icon like we did before, and selecting Document Activity, you can see that the drawing was synced in Autodesk 360 only minutes before.
If you refer back to Part 2 of this series, I showed you how to use Autodesk 360 to work with updated drawings and how you can collaborate with your stored documents in Autodesk 360. With the addition of AutoCAD WS on a mobile device (in this case, the iPad), you now have the ability not only to collaborate, but design on the fly, using a mobile device and show the document changes in Autodesk 360 as you go. I stated that this leads to faster implementation of your design on site or on the factory shop floor.
Faster implementation and, as you now see, easy remote syncing of both drawings and regular documents makes for a much slicker workflow. The remote location using Wi-Fi and any kind of enabled tablet (not just an iPad, it could be an Android device, even a Kindle Fire) allows any organization to work GLOBALLY and almost anywhere.
The cloud is here and it is being used in many ways already. Autodesk are providing some superb tools that can be used with some of the cutting edge devices that are out there, such as the iPad, the Motorola Xoom (amongst many others). This technology WILL (and already is) revolutionizing the way we work with not only CAD, but with all the documents used in the design process such as specifications, OEM manuals and the like. A typical example was the MS Word document in this part of the series.
This is Part 4 of 4 for this series, so I bid you farewell for now but keep an eye for further blogs about tablet devices and mobile workflows!

Here at CADspeed, we get a lot of questions about buying new hardware for CAD applications. While the answer to, “What CAD hardware should I buy?” varies widely based on the person asking the question, it always starts in the same place: with the requirements of the CAD software you plan to use.
Yet a list of minimum requirements can be, well, only minimally helpful in the quest for the right CAD workstation. Most CAD users need hardware that will not just meet the minimum specifications, but enable them to maximize their productivity.
CAD software developers know this, and they have a vested interest in making sure you get the bang for your software buck. So this series will explore recommended hardware for a variety of common CAD applications from the makers of the applications themselves.
We start this series with Autodesk, creator of 3D design, engineering and entertainment software that includes some of the most commonly used applications in the industry. Autodesk has developed a web site to help users find certified or recommended software for Autodesk applications.
The truth is, however, many CAD users don’t use just one CAD software application. It’s very common to use both AutoCAD and Revit on the same system, for example. The intriguing part of the Autodesk hardware site is you can select multiple products and find the common driver and hardware configurations that will work best for your system.
Certified vs. Recommended
On the Autodesk website, you’ll see two terms that you need to understand: certified and recommended. “Certified” hardware meets Autodesk’s minimum hardware requirements for the applicable Autodesk software product. At least one configuration (e.g., GPU + driver, or CPU + GPU + RAM + HD + BIOS) has passed tests designed to verify that the hardware supports the product’s features.
“Recommended” hardware meets Autodesk’s recommended system requirements for the applicable Autodesk product. At least one configuration has passed tests designed to verify that the hardware supports the product’s features.
A “Recommended” or “Certified” rating is based on the test results for a graphics card and driver or a complete system. Clicking the link for a card or system will reveal the results of each individual component tests.
|Recommended – Meets Autodesk’s recommended system requirements and has passed all Autodesk certification tests.|
|Certified – Meets Autodesk’s minimum system requirements and has passed all Autodesk certification tests.|
|Icon||Component Test Results*|
|Passed – When tested with this configuration, the hardware passed testing.|
|Passed with issues – When tested with this configuration, the hardware has some minor problems or features that are not supported.|
|Failed – When tested with this configuration, the hardware does not adequately support the product’s features.|
|No Results – This configuration has not been tested by the associated product.|
* Test results are valid only for the tested combination of hardware and driver. Certified or Recommended status does not guarantee that the graphics hardware will operate acceptably with other drivers or configurations. Driver-specific test results are available for some hardware and can be found by clicking on a product name in the Hardware List.
Other Terms to Understand
Before using the Autodesk Certified Hardware site, you should understand a few other common terms to make sure you are getting the right results.
- Workstation—Graphics hardware designated by the manufacturer as workstation-grade, typically meaning it is designed to work with 3D CAD applications
- Consumer—Graphics hardware designated by the manufacturer for desktop or gaming level use, typically meaning it is not designed or recommended for use with 3D CAD applications
- Mobile—Integrated hardware normally found in laptops.
- Workstation Desktop—Desktop system designated by the manufacturer as workstation-grade, typically meaning it is designed to work with 3D CAD applications
- Workstation Laptop—Laptop designated by the manufacturer as workstation-grade, typically meaning it is designed to work with 3D CAD applications
- Consumer Desktop—Desktop system designated by the manufacturer for desktop or gaming level use, typically meaning it is not designed or recommended for use with 3D CAD applications
- Consumer Laptop—Laptop designated by the manufacturer for desktop or gaming level use, typically meaning it is not designed or recommended for use with 3D CAD applications.
- Tablet—Touch-screen device with integrated components.
The Hardware List page contains only the hardware products that Autodesk has tested for use with certain Autodesk applications. Autodesk tests a variety of hardware, but focuses primarily on hardware the manufacturer has indicated is workstation-grade and designed to work with 3D CAD applications.
Unless otherwise noted, Autodesk hardware certification tests are run on systems containing a single video card with a single monitor attached. Autodesk does not currently run certification tests on systems with multiple graphics cards installed or multiple monitors.

Where do you begin your quest for the right workstation? This particular hardware search should start with your software.
Let’s be real: Nobody relies on just one application over the course of a day. We’re all bouncing between disparate tasks and windows. But for the majority of CAD professionals, there is one application — or maybe a couple — that consumes the bulk of your hours at the desk. What’s the app that dominates your day? Got it? Now hit the web site of the software developer and find the minimum and recommended system requirements for your killer app. AutoCAD users can find this information at http://usa.autodesk.com/autocad/system-requirements.
Minimum is the Starting Point Only
In most cases, an application’s minimum requirements set an extremely low standard, as the software vendors begrudgingly must address the least common denominator of the installed base. We don’t recommend you follow these guidelines, but it’s worth making a note of the minimum graphics, system memory and CPU requirements. On the other hand, it’s highly likely that any new workstation on the market today will meet or exceed these numbers.
More interesting is the list of recommended or certified hardware. For SolidWorks, Dassault Systèmes (as of this writing) specifies a minimum of 1 GB RAM, but suggests 6 GB. Well, if you go with 1 GB, you’ll be sorry — even 6 GB isn’t necessarily the best choice, depending on your budget, and especially given the incredible amount of gigabytes/dollar that can be had today.
Similarly, Autodesk isn’t going to stop you from running a PC gamer graphics card, but the company will tell you which cards are optimized for performance and built for reliability when it comes to supporting AutoCAD or Autodesk Inventor.
Increasingly, the only CAD-certified graphics cards are professional-brand NVIDIA Quadro and AMD FirePro. That’s because software developers have consistently seen the fewest bugs and problems with cards that, like the system overall, have been exhaustively tested and tuned for professional workstation applications. In fact, the major CAD software developers will help you address issues related to running a Quadro or FirePro card, but they dedicate no support cycles to fixing bugs on consumer-class hardware.
In Part 2 of this series, I showed you some of the functionality of Autodesk 360. We are now going to look at how we collaborate using Autodesk 360, using a fixed location (PC on a network) and a mobile location (iPad on a remote site with Wi-Fi).
Your Documents Are Synced, What Happens Now?
Using AutoCAD 2013 In A Fixed Location
As mentioned in Part 2 of the series, all of the Autodesk 2013 product range now include an Autodesk 360 tab on the ribbon interface. We will be using this in a fixed location when you are already logged in. Click on the Online tab on the AutoCAD 2013 ribbon interface.
So, right now, you will have your Autodesk 360 browser window open (it works best in Microsoft IE9) and your AutoCAD 2013 is done and uploaded to Autodesk 360 ready to go. That is your fixed location all set.
Using Autodesk 360 In A Mobile Location
So now we need to think about the mobile location. I am running Autodesk 360 and AutoCAD WS on my iPad, so let’s check this out.
I first use my browser on my iPad (normally Safari by default) to logon to Autodesk 360. Once I am logged in, I can browse my documents in my Autodesk 360 folders. In this case, it is the AEC Plan Elev Sample Drawing, already loaded in Autodesk 360. I know this is a default sample drawing, but for speed’s sake, use this as the drawing you have just loaded up from AutoCAD 2013 to Autodesk 360, using the Online tab in AutoCAD.
I can click on the button shown and on the sub-menu, I can open up the drawing from Autodesk 360 using AutoCAD WS on my iPad.
Upon clicking on the Edit in AutoCAD WS option, I am prompted to install AutoCAD WS on my iPad from the App Store, if I haven’t done so already.
If AutoCAD WS is already there on the iPad, you just load up AutoCAD WS and the new drawing will be there in your drawing list, as shown below (drawing is at the bottom of the list).
You can now open the drawing in your mobile (remote) location on your iPad and edit the drawing accordingly based on whatever data you have at that location. You can now see the value of AutoCAD WS on a mobile device, as per my first series of articles about AutoCAD WS.
If you refer back to Part 2 of this series, I show you how to use Autodesk 360 to work with updated drawings and how you can collaborate with your stored documents in Autodesk 360. With the addition of AutoCAD WS on a mobile device (in this case, the iPad), you now have the ability not only to collaborate, but design on the fly, using a mobile device and show the document changes in Autodesk 360 as you go. This leads to faster implementation of your design on site or on the factory shop floor.
The cloud is here and it is now. Autodesk are moving forward fast with this technology and it WILL revolutionize the way we work with not only CAD, but all the documents used in the design process such as specifications, OEM manuals and the like.
As I said in Part 2 of this series, it will allow us to embrace the mobile CAD movement and start to mobilise the CAD office/function in ways we never thought possible.
Stay tuned for Part 4 of this series, where I will show you how changes in documents and drawings are synchronised using Autodesk 360.

Reality capture is a boom business for the building industry. With roughly 5 million existing commercial buildings in the United States alone, it’s easy to understand why. Laser-scanner-based reality capture is the dominant methodology used today to accurately capture the 3D state of an existing building. However, the typical laser-scan-based point cloud is in the hundreds of millions of 3D points, sometimes even going into the billions of points. With this additional data overhead on top of an already dense Building Information Model, it’s important to optimize your workstation hardware to deliver a productive user experience.
Finding the Bottleneck
Under the hood, Autodesk Revit utilizes the PCG point cloud engine to rapidly access the 3D points contained in point cloud and retrieve points to be displayed in the current Revit View. Since the typical point cloud dataset is so large, a workstation’s RAM is insufficient to be used as the means for access by the PCG engine in Revit. Instead, the disk drive is used for access, while a small amount of System RAM and Video RAM is used for the current Revit View. Thus, the hard drive is commonly the limiting factor for point cloud performance, rather than system RAM, CPU, or GPU.
Learn the Options
With data access a common limiting factor to the performance of the Revit point cloud experience, let’s discuss the options available to deliver the best experience. There are two primary types that are found today: spinning platter and solid-state drives.
- Spinning platter drives are the traditional hard drive technology, and are found in most computers today, as they deliver the best balance of storage capacity, read/write access speed, and cost.
- Solid-state drives (SSDs) are relatively new technology, contain no moving parts, and are generally much faster at reading and writing data than typical spinning platter drives.
In a structured comparison completed by the Revit product team, we found the following results when comparing typical versions of these Disk Drive types:
Reap the Benefits
Based upon this investigation, we would highly recommend that those looking to optimize their Revit workstations for point cloud use install an SSD for at least the local storage of the point cloud data. While you will also achieve additional benefits from running the entire OS on your SSD, a significant performance boost can be achieved through the retrofit of a ~$200 SSD to an existing workstation.
